D.Ed. Special Education (HI) Notes – Paper No 5 FUNDAMENTALS OF SPEECH AND SPEECH TEACHING, Unit 2: Description of speech sounds

2.1 Non segmental: Intensity, pitch and quality

Non-Segmental Features of Speech: Intensity, Pitch and Quality

Speech is not only made up of separate sound units like vowels and consonants. These sound units are called segmental features. But beyond these, there are certain features that spread over several sounds or syllables and give speech its natural rhythm, flow, melody, and emotion. These are called non-segmental or suprasegmental features.

The main non-segmental features of speech include:

• Intensity (Loudness)
• Pitch (Highness or Lowness of sound)
• Quality (Timbre or texture of voice)

These features help in:

• Communicating emotions
• Giving meaning to speech beyond the words
• Making speech sound natural and pleasant
• Helping the listener understand the speaker’s intent

Let us now understand each feature in detail.

Intensity

Meaning of Intensity

Intensity is the loudness or softness of speech. It is the amount of energy or force with which air is pushed through the vocal cords. It plays an important role in making speech audible and clear.

Intensity is measured in decibels (dB).

• More air pressure = Louder sound (High intensity)
• Less air pressure = Softer sound (Low intensity)

How intensity is produced

The respiratory system controls the amount of air that goes through the vocal cords. The stronger the air pressure, the more forcefully the vocal cords vibrate, and this produces greater intensity or loudness.

The phonatory system, which includes the vocal cords, helps to control the volume of speech through tension and vibration speed.

Functions of intensity in speech

• To stress or emphasize a word or part of a word (e.g., “I DID it”, “I did IT”)
• To express emotions like anger (loud) or fear (soft)
• To adjust speech according to the environment (e.g., loud in a noisy place, soft in a quiet room)
• To support natural rhythm and stress patterns of language

Examples in daily life

• A teacher may raise intensity to get students’ attention.
• A person may lower intensity to whisper a secret.
• In storytelling, intensity may increase during exciting parts and decrease during sad moments.

Variations in intensity

Intensity can vary based on:

• Physical condition (fatigue, illness may reduce intensity)
• Emotional state (anger increases intensity)
• Social situations (formal vs. informal speech)
• Speech purpose (conversation, announcement, storytelling)

Disorders related to intensity

• Hearing impairment: The person may not hear themselves properly and may speak too loudly or too softly.
• Voice disorders like vocal nodules or polyps can reduce the ability to produce strong sounds.
• Neurological disorders like Parkinson’s disease can cause weak, low-intensity voice.
• Psychological issues like anxiety may lead to soft or shaky speech.

Impact on communication

• Incorrect intensity can cause misunderstanding.
• Low intensity may make the speaker sound unconfident or tired.
• Very high intensity may be perceived as rude or aggressive.
• Balanced intensity improves clarity, emotional expression, and engagement.

Role of speech therapist

• Teach the child/client how to control loudness using exercises.
• Use tools like voice meters and auditory feedback systems.
• Teach breathing techniques to support stronger vocal output.
• Guide on vocal hygiene to avoid misuse or overuse of voice.

---

Pitch

Meaning of Pitch

Pitch is the highness or lowness of a person’s voice. It is based on the frequency of vibration of the vocal cords.

• High frequency = High pitch (e.g., a child’s voice)
• Low frequency = Low pitch (e.g., a man’s deep voice)

Pitch is measured in Hertz (Hz).

It is a very important element in making speech musical, meaningful, and expressive.

How pitch is produced

Pitch is controlled by the tension and length of the vocal cords:

• Tight and thin vocal cords = Faster vibration = Higher pitch
• Loose and thick vocal cords = Slower vibration = Lower pitch

Pitch also depends on:

• Gender (females generally have higher pitch)
• Age (children have higher pitch than adults)
• Hormonal changes (especially during puberty)
• Emotional states (nervousness, excitement)

Functions of pitch in speech

• To express different emotions (e.g., sadness, excitement, surprise)
• To distinguish between types of sentences (question vs. statement)
• To emphasize certain words or ideas
• To make speech lively and musical

Examples in daily life

• Rising pitch in “Are you okay?” signals a question.
• Falling pitch in “I am okay.” signals a statement.
• Varying pitch helps make storytelling more engaging.
• Monotone (same pitch) makes speech boring or robotic.

Disorders related to pitch

• Monotone speech seen in autism or Parkinson’s disease.
• Abnormal pitch like too high or too low due to vocal cord issues.
• Pitch breaks in teenagers due to puberty.
• Pitch instability in people with anxiety or neurological conditions.

Impact on communication

• Lack of pitch variation can make speech sound dull or emotionless.
• Incorrect pitch can lead to misinterpretation of feelings.
• Proper pitch helps in clarity, emotion, and listener interest.

Role of speech therapist

• Teach intonation patterns and pitch variation.
• Use musical exercises, humming, or reading with varied pitch.
• Use apps or pitch tracking tools to give visual feedback.
• Strengthen vocal cord control through regular practice.

Quality of Speech

Meaning of Speech Quality

Speech quality refers to the overall sound, texture, or tone of a person’s voice. It is what makes one voice different from another. Even if two people say the same word at the same pitch and loudness, their voice quality may still sound different.

Voice quality is shaped by:

• The vocal cords and how they vibrate
• The vocal tract (mouth, nose, throat, pharynx) and how it resonates
• The way air flows and is controlled during speech

This combination gives each person a unique vocal signature or voice print.

Characteristics of normal voice quality

A normal voice quality is:

• Clear
• Pleasant to hear
• Smooth and natural
• Free from strain, breathiness, or harshness
• Consistent in sound (not shaky or hoarse)

Types of voice quality

There are different voice qualities that can be normal variations or signs of a disorder. Some of the most common types include:

1. Breathy voice
   • Too much air escapes with the voice
   • The voice sounds soft and airy
   • May occur due to weak vocal cord closure
   • Example: a tired or emotional person speaking gently
2. Harsh voice
   • The voice sounds rough, tight, or strained
   • Caused by excessive tension in vocal cords
   • May happen due to shouting, overuse of voice, or stress
3. Hoarse voice
   • A combination of breathy and harsh voice
   • Sounds rough and unclear
   • Common during throat infections or after excessive talking or shouting
4. Nasal voice
   • Caused by abnormal air flow through the nasal cavity
   • Hypernasal: Too much air escapes through the nose
   • Hyponasal: Not enough air passes through the nose
   • Hypernasality may occur in cleft palate
   • Hyponasality may occur during a cold or nasal blockage

Factors that affect voice quality

• Physical structure of vocal cords and vocal tract
• Health of the larynx (voice box)
• Use or misuse of the voice
• Nasal and oral cavity conditions
• Emotional state (e.g., stress can make the voice sound tight)
• Hydration level and lifestyle habits (e.g., smoking, alcohol)

Importance of voice quality in communication

• Voice quality affects how pleasant or unpleasant a voice sounds
• It can show personality traits or emotions
• It makes speech clear, attractive, and easy to understand
• Poor quality may distract listeners or make speech hard to follow

Disorders related to voice quality

1. Voice disorders (dysphonia)
   • Includes problems like nodules, polyps, cysts on vocal cords
   • Can make voice sound hoarse, strained, or breathy
2. Cleft palate
   • Causes abnormal nasal resonance
   • Leads to hypernasal voice
3. Neurological disorders
   • Conditions like vocal cord paralysis or Parkinson’s disease may affect voice quality
4. Muscle tension dysphonia
   • Caused by excess tension in the muscles of the voice box
   • Leads to rough or strained voice
5. Laryngitis
   • Inflammation of the vocal cords
   • Leads to hoarseness or loss of voice

Impact on communication

• Affects clarity and effectiveness of speech
• May reduce confidence and social participation
• Can lead to misunderstandings or people avoiding communication
• May affect speech intelligibility, especially in classroom or public settings

Role of speech therapist

• Voice evaluation to identify the type of disorder
• Teaching healthy voice habits (e.g., proper hydration, avoiding shouting)
• Training in relaxation and breathing techniques
• Resonance therapy to correct nasal voice
• Use of amplification devices if needed
• Working on vocal cord strength and control

2.2 Segmental aspects of speech: Definition of consonants, vowels, diphthong and blends

Segmental Aspects of Speech

Segmental aspects of speech refer to the individual sounds or phonemes that are produced in spoken language. These sounds are the smallest units of speech that can change the meaning of a word. Segmental speech sounds are divided mainly into consonants and vowels, along with special combinations like diphthongs and blends. These are essential in speech development, articulation, and speech correction.

Understanding these elements is very important in the teaching of speech, especially for children with hearing impairment, because these are the building blocks of spoken language.

---

Definition of Consonants

Consonants are speech sounds that are produced when the airflow from the lungs is partly or completely blocked by the tongue, lips, teeth, or other parts of the vocal tract.

Consonants are not produced by a free flow of air. Instead, there is some obstruction or closure in the vocal tract which gives each consonant its unique sound.

Examples:
/b/ in “bat”, /k/ in “kite”, /t/ in “top”

Key Features of Consonants:

• Place of Articulation: Where the sound is produced in the mouth (e.g., lips, teeth, back of the mouth).
  Examples:
  • /p/ and /b/ are bilabial (produced using both lips)
  • /t/ and /d/ are alveolar (produced using the tongue and the alveolar ridge)
• Manner of Articulation: How the sound is produced, or how the airflow is restricted.
  Examples:
  • /s/ and /z/ are fricatives (air passes through a narrow space causing friction)
  • /m/ and /n/ are nasals (air passes through the nose)
• Voicing: Whether the vocal cords vibrate during the sound.
  • Voiced consonants: /b/, /d/, /g/ (vocal cords vibrate)
  • Voiceless consonants: /p/, /t/, /k/ (vocal cords do not vibrate)

Consonants usually appear at the beginning, middle, or end of syllables and words. They help to give shape and structure to words in spoken language.

---

Definition of Vowels

Vowels are speech sounds that are produced without any blockage or restriction of airflow in the vocal tract. The air flows freely through the mouth when we say vowel sounds.

Vowels are always voiced, meaning the vocal cords vibrate when producing them.

Examples:
/a/ as in “apple”, /e/ as in “elephant”, /i/ as in “ink”, /o/ as in “orange”, /u/ as in “umbrella”

Key Features of Vowels:

• Tongue Position: The height (high, mid, low) and front-back position (front, central, back) of the tongue determines the vowel sound.
  Examples:
  • /i/ in “see” is a high front vowel
  • /a/ in “father” is a low back vowel
• Lip Rounding: Some vowels are made with rounded lips, others with unrounded lips.
  Examples:
  • /u/ as in “boot” – lips are rounded
  • /i/ as in “bit” – lips are not rounded
• Length: Vowels can be short or long in duration.
  • Short: /i/ as in “bit”
  • Long: /i:/ as in “beet”

Vowels are the core of a syllable. Every syllable in a word contains at least one vowel sound.

Definition of Diphthongs

Diphthongs are complex vowel sounds that begin with one vowel sound and glide into another within the same syllable. The tongue moves during the articulation of diphthongs, unlike pure vowels where the tongue stays in one position.

They are also known as gliding vowels because of this movement from one vowel position to another.

Examples:

• /aɪ/ as in “ice”
• /aʊ/ as in “cow”
• /ɔɪ/ as in “boy”
• /eɪ/ as in “day”
• /oʊ/ as in “go”

Key Features of Diphthongs:

• A diphthong is made up of two vowel sounds joined together in a single syllable.
• The first vowel is the starting point, and the second vowel is the glide.
• They are always voiced and carry the main stress in a syllable.
• The tongue and jaw both shift during the pronunciation.

Diphthongs are important in understanding variations in pronunciation across different regions and accents. Teaching diphthongs helps learners recognize natural transitions in spoken language.

---

Definition of Blends

Blends are two or more consonant sounds that appear together in a word, but each sound can still be heard. In blends, the sounds are not combined into one like in digraphs (e.g., /sh/, /ch/), but instead, each sound is pronounced distinctly.

Blends typically appear at the beginning or end of words.

Examples:

• Beginning blends:
  • /bl/ as in “black”
  • /tr/ as in “tree”
  • /sp/ as in “spoon”
• Ending blends:
  • /nd/ as in “sand”
  • /mp/ as in “lamp”
  • /st/ as in “fast”

Key Features of Blends:

• Consist of 2 or 3 consonants.
• Each consonant keeps its own sound, even though they are spoken together quickly.
• Blends help to form syllables and are common in many words in English.
• Teaching blends is essential for reading, spelling, and pronunciation skills, especially in children with speech or language difficulties.

Blends help build fluency and decoding skills in early reading and speech training. For learners with hearing loss, clear teaching of blends helps avoid common speech errors.

2.3 Classification of consonants – place, manner, voicing

Classification of Consonants – Place, Manner, Voicing

Consonants are speech sounds that are produced by obstructing the airflow in some way using the speech organs. They are classified based on three major features:

• Place of Articulation – where the sound is produced in the vocal tract
• Manner of Articulation – how the airflow is shaped or blocked
• Voicing – whether the vocal cords vibrate or not during sound production

Let us understand each of these in detail.

---

Place of Articulation

Place of articulation refers to the point in the mouth or throat where the speech organs come together or near each other to block or restrict airflow and produce sound.

1. Bilabial

• Both lips come together.
• Examples: /p/, /b/, /m/
• Sounds: pat, bat, mat

2. Labiodental

• The lower lip touches the upper front teeth.
• Examples: /f/, /v/
• Sounds: fan, van

3. Dental (or Interdental)

• The tongue tip is placed between the upper and lower teeth.
• Examples: /θ/ as in think, /ð/ as in this

4. Alveolar

• The tongue touches or gets close to the alveolar ridge (just behind the upper front teeth).
• Examples: /t/, /d/, /s/, /z/, /n/, /l/
• Sounds: top, dip, sip, zip, nap, lip

5. Post-Alveolar

• The tongue is placed slightly behind the alveolar ridge.
• Examples: /ʃ/ as in shoe, /ʒ/ as in measure, /tʃ/ as in chop, /dʒ/ as in judge

6. Retroflex

• The tongue tip curls back slightly toward the palate.
• Common in Indian languages like Hindi and Tamil.
• Examples: /ʈ/, /ɖ/, /ɳ/

7. Palatal

• The middle part of the tongue rises to touch or come close to the hard palate.
• Example: /j/ as in yes

8. Velar

• The back of the tongue touches the soft palate (velum).
• Examples: /k/, /g/, /ŋ/ as in king

9. Glottal

• The sound is made by using the vocal cords or the glottis.
• Examples: /h/, glottal stop [ʔ] as in uh-oh

Manner of Articulation

Manner of articulation describes how the airstream is modified when it passes through the vocal tract during the production of a consonant. It explains the type of closure or narrowing involved in sound production.

1. Plosive (Stop Sounds)

• The airflow is completely blocked and then suddenly released.
• Examples: /p/, /b/, /t/, /d/, /k/, /g/
• Sounds: pen, bat, top, dog, cat, go

2. Nasal

• The airflow is completely blocked in the mouth, but allowed to pass through the nose.
• Examples: /m/, /n/, /ŋ/
• Sounds: man, nice, sing

3. Fricative

• The airflow is only partially blocked, creating friction as it passes through a narrow gap.
• Examples: /f/, /v/, /s/, /z/, /ʃ/, /ʒ/, /θ/, /ð/
• Sounds: fan, van, sip, zip, shoe, treasure, think, this

4. Affricate

• A combination of plosive and fricative: air is first stopped and then released with friction.
• Examples: /tʃ/, /dʒ/
• Sounds: chair, judge

5. Lateral

• The airflow is blocked at the centre of the mouth, but allowed to pass along the sides of the tongue.
• Example: /l/
• Sound: lip

6. Approximant (Glide)

• The articulators come close together, but not enough to create a turbulent airstream.
• Examples: /w/, /j/, /r/
• Sounds: we, yes, run

7. Flap or Tap

• A single, quick contact between articulators.
• Common in Indian languages and in American English as the soft ‘t’ in butter.
• Example: /ɾ/

---

Voicing

Voicing refers to whether the vocal cords vibrate during the production of a consonant sound.

1. Voiced Consonants

• The vocal cords vibrate while making the sound.
• Examples: /b/, /d/, /g/, /v/, /z/, /ʒ/, /dʒ/, /m/, /n/, /ŋ/, /l/, /r/, /j/, /w/
• Try placing fingers on your throat while saying “zoo” – you will feel vibration.

2. Voiceless Consonants

• The vocal cords do not vibrate.
• Examples: /p/, /t/, /k/, /f/, /s/, /ʃ/, /θ/, /tʃ/, /h/
• No vibration is felt in the throat when you say “sock”.

---

Together, these three characteristics—Place, Manner, and Voicing—help in the clear classification and understanding of consonants. This knowledge is very important in the field of speech-language therapy, phonetics, and speech teaching, especially for children with hearing impairment.

2.4 Classification of vowels

Classification of Vowels

What are Vowels?

Vowels are speech sounds produced when the air flows out freely through the mouth without being blocked by any part of the vocal tract. While pronouncing vowels, the tongue, lips, and jaw may change their position, but the airstream is never stopped. In contrast to consonants, vowels are continuous sounds. Every syllable in a word must contain a vowel sound, which makes vowels the core of speech production.

Vowels are voiced sounds, meaning the vocal cords vibrate when they are spoken. The sound of each vowel depends on how high or low the tongue is, how far forward or backward it is placed in the mouth, whether the lips are rounded or not, and other physical features of articulation.

To better understand how vowel sounds are produced, they are classified based on different features. These features include:

1. Height of the tongue
2. Part of the tongue used
3. Shape of the lips
4. Length or duration of the vowel
5. Tenseness of the muscles
6. Movement of speech organs (monophthong or diphthong)

Each of these features will now be explained in detail.

---

1. Height of the Tongue (Vertical Tongue Position)

This refers to how high or low the tongue is in the mouth during the production of the vowel sound.

• High vowels (also called close vowels)
  In these vowels, the tongue is raised high, close to the roof of the mouth.
  Examples:
  /iː/ as in seat
  /uː/ as in goose
• Mid vowels
  The tongue is placed halfway between a high and a low position.
  Examples:
  /e/ as in bed
  /ə/ as in about
• Low vowels (also called open vowels)
  The tongue is positioned low in the mouth, away from the roof.
  Examples:
  /æ/ as in cat
  /ɑː/ as in car

This classification is essential because tongue height affects how open the mouth is during the sound. High vowels have a smaller mouth opening, while low vowels have a wider mouth opening.

---

2. Tongue Position (Front, Central, and Back)

This refers to how forward or backward the tongue is placed in the mouth when the vowel is spoken.

• Front vowels
  The tongue is pushed forward in the mouth. These vowels sound bright.
  Examples:
  /iː/ as in machine
  /ɪ/ as in bit
  /e/ as in bed
  /æ/ as in cat
• Central vowels
  The tongue stays in the centre of the mouth. These vowels are neutral and common in unstressed syllables.
  Examples:
  /ʌ/ as in cup
  /ə/ as in sofa
• Back vowels
  The tongue is pulled back in the mouth. These vowels sound deep and full.
  Examples:
  /uː/ as in boot
  /ʊ/ as in book
  /ɔː/ as in law
  /ɑː/ as in father

Tongue position plays a major role in vowel quality, and it also affects accent and pronunciation.

---

3. Lip Shape (Rounded and Unrounded)

The position of the lips during vowel production also helps in classifying vowels.

• Rounded vowels
  The lips form a circular shape or are pushed forward. Rounded vowels are usually back vowels.
  Examples:
  /uː/ as in blue
  /ʊ/ as in book
  /ɔː/ as in thought
• Unrounded vowels
  The lips are relaxed or spread. These are often front vowels.
  Examples:
  /iː/ as in see
  /ɪ/ as in bit
  /e/ as in pen

The shape of the lips changes the resonance of the sound and helps distinguish similar vowel sounds.

---

4. Length of Vowel Sound (Short and Long Vowels)

Vowel sounds can be classified based on how long they are held during pronunciation.

• Short vowels
  These vowels are produced for a short duration. They are typically used in closed syllables.
  Examples:
  /ɪ/ in sit
  /ʌ/ in cut
  /ə/ in banana
• Long vowels
  These vowels are held longer. They are often used in open syllables or stressed syllables.
  Examples:
  /iː/ in seat
  /uː/ in goose
  /ɑː/ in car

In English, vowel length can change word meanings. For example: ship (short /ɪ/) vs sheep (long /iː/).

---

5. Muscle Tension (Tense and Lax Vowels)

This classification is based on the muscular effort needed to produce the vowel.

• Tense vowels
  These vowels are produced with greater muscle effort. They are usually longer and clearer in sound.
  Examples:
  /iː/ in seen
  /uː/ in soon
• Lax vowels
  These vowels require less effort and are generally shorter.
  Examples:
  /ɪ/ in sit
  /ʊ/ in put

Tense vowels are more common in stressed syllables, while lax vowels are used in unstressed or weak syllables.

---

6. Monophthongs and Diphthongs

This classification depends on whether the sound stays the same or changes during pronunciation.

• Monophthongs
  These are pure vowel sounds. The tongue and lips stay in one position while the sound is produced.
  Examples:
  /iː/, /æ/, /ʌ/, /ɔː/, /ə/
• Diphthongs
  These are combined vowel sounds where the tongue and lips glide from one position to another.
  Diphthongs are important in English and are often used in fluent speech.
  Common diphthongs:
  /aɪ/ in my
  /eɪ/ in day
  /aʊ/ in now
  /əʊ/ in go
  /ɔɪ/ in boy

Diphthongs are longer and more complex than monophthongs.

---

7. Summary Chart of English Vowel Classification

This chart shows how vowels can be arranged based on tongue height (high to low) and tongue position (front to back):

Tongue Height	Front Vowels	Central Vowels	Back Vowels
High	/iː/, /ɪ/		/uː/, /ʊ/
Mid	/e/, /ɛ/	/ʌ/, /ə/	/ɔː/
Low	/æ/		/ɑː/

2.5 Supra-segmental: Intonation, stress, pause, etc.

Supra-segmental: Intonation, Stress, Pause, etc.

Suprasegmental features are also called prosodic features. These are speech features that go beyond the level of individual sounds (segmental sounds such as consonants and vowels). Instead, they operate at the level of syllables, words, phrases, and sentences. Suprasegmentals add meaning, rhythm, emphasis, and emotion to speech.

They play a vital role in how speech is understood, and they contribute to the natural flow and musical quality of spoken language. These features include intonation, stress, pause, rhythm, pitch, and juncture.

Let us understand the major suprasegmental features in detail.

---

Intonation

Intonation refers to the variation in the pitch level of the voice while speaking. It is the rise and fall of the voice that occurs in connected speech. It is not about how high or low the voice is in general, but how the pitch moves during speech.

Importance of Intonation:

• It helps express emotions such as anger, happiness, surprise, etc.
• It helps to differentiate types of sentences: declarative, interrogative, imperative, or exclamatory.
• It indicates whether the speaker has finished speaking or is going to continue.
• It can change the meaning or intention of the sentence.

Types of Intonation Patterns:

1. Falling Intonation
   • The pitch falls at the end of the sentence.
   • Common in statements, commands, and WH-questions.
   • Example: She is going to school. (↘)
   • Example: What is your name? (↘)
2. Rising Intonation
   • The pitch rises at the end of the sentence.
   • Common in Yes/No questions, and expressions of doubt or surprise.
   • Example: Are you coming? (↗)
3. Fall-Rise Intonation
   • The pitch falls and then rises again.
   • Often used to show uncertainty, politeness, or continuation.
   • Example: I may come later… (↘↗)
4. Rise-Fall Intonation
   • The pitch rises and then falls.
   • It may express strong feelings like admiration or surprise.
   • Example: Really! (↗↘)

---

Stress

Stress refers to the emphasis placed on certain syllables or words in speech. Stressed parts are said louder, longer, and often with a higher pitch.

Types of Stress:

1. Word Stress
   • Within a word, one syllable is stressed more than others.
   • Example: TAble, REcord (noun), reCORD (verb)
   • Stress can change the meaning or part of speech of a word.
2. Sentence Stress
   • Certain words in a sentence are given more emphasis.
   • Usually, content words (nouns, main verbs, adjectives, adverbs) are stressed, while function words (prepositions, articles, auxiliary verbs) are not.
   Example:
   • I want to BUY a new CAR. (content words are stressed)
3. Contrastive Stress
   • Stress is used to highlight a contrast or correct information.
   • Example:
     • I said SHE is coming, not he.
     • He is not my FRIEND, he is my BROTHER.
4. Emphatic Stress
   • Stress is used to emphasize something important.
   • Example:
     • This is REALLY important!
     • I do LOVE chocolate!

---

Pause

A pause is a break or a short stop in speech. It helps in organizing speech, creating impact, and aiding listener understanding.

Types of Pauses:

1. Breath Pause
   • Natural pause taken for breathing while speaking.
2. Sense Pause
   • A pause taken at natural breaks in meaning or sentence structure.
   • Helps in separating phrases or clauses.
   Example:
   • After the meeting, (pause) we will go for lunch.
3. Emphasis Pause
   • Used to highlight or emphasize a word or idea.
   • Example:
     • She is the winner… without a doubt.
4. Suspense Pause
   • Used to create interest or suspense.
   • Often used in storytelling or drama.
   • Example:
     • And the winner is… Rajesh!
5. Emotional Pause
   • Reflects emotions like sadness, hesitation, or surprise.
   • Example:
     • I… I don’t know what to say.

Rhythm

Rhythm in speech refers to the pattern of stressed and unstressed syllables. It gives a musical flow or beat to spoken language, just like in music. In English, rhythm is stress-timed, meaning the stressed syllables occur at regular intervals, and unstressed syllables are shortened to fit in between.

Features of Rhythm:

• It helps to make speech clear and understandable.
• It adds natural flow and beauty to spoken language.
• Good rhythm improves fluency in communication.
• It helps the listener to predict and follow the speech.

Examples:

• He ‘WENT to the ‘SHOP to buy some ‘BREAD.
  (The stressed syllables are marked in capital.)

Rhythm is closely connected to stress and intonation. When these features are used correctly, speech becomes smooth and effective.

---

Pitch

Pitch is the highness or lowness of the speaker’s voice. It is determined by the frequency of vocal cord vibration. Pitch is an important feature of intonation and varies depending on the emotion, purpose, and meaning of the sentence.

Functions of Pitch:

• It helps to express emotions such as excitement, anger, sadness, etc.
• It gives structure to speech, marking beginnings, endings, and emphasis.
• It indicates the speaker’s attitude.

Types of Pitch Movements:

1. High Pitch
   • Used to show excitement, surprise, or emphasis.
   • Example: What a beautiful dress!
2. Low Pitch
   • Used to show seriousness, finality, or sadness.
   • Example: I am very tired today.
3. Rising Pitch
   • Usually occurs at the end of Yes/No questions.
   • Example: Are you coming home?
4. Falling Pitch
   • Occurs in statements and WH-questions.
   • Example: Where are you going?
5. Level Pitch
   • Indicates boredom, monotony, or lack of emotion.
   • Example: I did it yesterday.

---

Juncture

Juncture refers to the pause or transition between words or sounds in speech. It helps in separating or joining words correctly. Juncture affects the meaning of a sentence depending on how words are grouped.

Types of Juncture:

1. Close Juncture
   • No pause between words. Words are said smoothly together.
   • Example: icecream (spoken as one word)
2. Open Juncture
   • A slight pause between words.
   • Example: I scream (spoken as two separate words)
3. Terminal Juncture
   • A strong pause indicating the end of a sentence.
   • Example: She is coming. (↘)
4. Non-terminal Juncture
   • A pause indicating that more is to come.
   • Example: If he comes, (pause) we’ll go to the party.

Juncture helps avoid confusion in speech. For example:

• Let’s eat, grandma! (with pause – correct)
• Let’s eat grandma! (without pause – wrong and dangerous)
