10. What is “Visual Phonics”?

Answers:

1. Resonance is the balance of sound between the oral and nasal cavities and the amplification of sound in those spaces.
2. Egressive airflow is air that travels outwards from the lungs, which is the basis for almost all speech sounds.
3. The three components are Physical Property (Frequency/Amplitude), Auditory Perception (Pitch/Loudness), and Spectrum (Quality).
4. It is a 3-step technique: Listen (no cues) $\rightarrow$ Look & Listen (visual cues) $\rightarrow$ Listen (no cues) to reinforce auditory pathways.
5. Prosody refers to the melody of speech, including rhythm, stress, and intonation.
6. Its primary function is to prevent food from entering the nasal cavity during swallowing.
7. Examples include Cleft Palate, Cerebral Palsy, or Hearing Impairment.
8. Signal-to-Noise Ratio.
9. Intelligibility is the degree to which a speaker’s message can be understood by a listener.

Short Answer Type Questions:

1. Explain why speech is called an “overlaid function.”
2. Briefly describe the three layers of speech training.
3. Differentiate between Speech and Language.
4. What are the common error patterns in the “HI Speech Profile”?
5. Describe the role of the Regulatory system in speech production.
6. What is “Acoustic Highlighting” and give two examples of its use.
7. Explain the “Place, Manner, and Voicing” classification of consonants.
8. Why is “Vegetative Function” training important for speech therapy?
9. Describe the “Ling Six Sound Test” and its purpose.
10. What are the secondary impacts of a speech disability on a child’s development?

Answers:

1. Overlaid Function: Speech organs (lungs, tongue, larynx) have primary biological roles (breathing, eating) necessary for survival. Speech is a “borrowed” function that evolved to use these same structures secondarily.
2. Three Layers: (1) Suprasegmentals (melody/pitch), (2) Segmentals (vowels/consonants), and (3) Secondary Parameters (quality/resonance).
3. Speech vs. Language: Speech is the physical motor act of sound production (Articulation/Voice). Language is the mental symbolic system of rules (Syntax/Semantics).
4. HI Profile: Omissions (dropping ends of words), Substitutions (using visible sounds for hidden ones), Nasality issues, and Vowel Neutralization.
5. Regulatory System: Acting as the “mastermind,” it handles motor planning in Broca’s area, comprehension in Wernicke’s, and uses auditory/tactile feedback to correct speech in real-time.
6. Acoustic Highlighting: Making sounds stand out by whispering to show breath, elongating a sound (“ssss-un”), or pausing before a word to create focus.
7. Consonant Classification: Place (where the obstruction is), Manner (how air is released, e.g., stops/fricatives), and Voicing (vibration or no vibration of vocal folds).
8. Vegetative Functions: Since speech is overlaid on eating/breathing, a child must master sucking, chewing, and swallowing to have the muscle strength and coordination required for clear articulation.
9. Ling Six: Uses sounds /a, u, i, m, sh, s/ to check if a child’s hearing aid/CI is working across low to high frequencies essential for speech.
10. Impacts: Includes academic struggles (reading/writing), social isolation, low self-esteem, and behavioral issues due to communication frustration.

Long Answer Type Questions:

1. Describe the five systems involved in the mechanism of speech production, including their key structures and functions.
2. Detail the pre-requisites and best practices for teaching speech to a child with a hearing impairment.
3. Classify and explain the various types of Speech and Language disorders (Articulation, Fluency, Voice, and Language).
4. Discuss the “Clinical Significance” of understanding the primary vs. secondary functions of speech organs in the context of Special Education.
5. Explain the Suprasegmental and Segmental parameters of speech and how they are specifically affected by hearing loss.

Answers:

1. Five Systems: * Respiratory: (Lungs/Diaphragm) Provides power via egressive airflow.
   • Phonatory: (Larynx) Converts air to sound via vocal fold vibration.
   • Resonatory: (Pharynx/Oral/Nasal cavities) Amplifies and colors the sound.
   • Articulatory: (Tongue/Lips/Teeth) Shapes sound into specific phonemes.
   • Regulatory: (Brain/Nerves) Coordinates and monitors the entire process.
2. Pre-requisites & Best Practices: Pre-requisites include optimal amplification (hearing aids/CI) and a quiet acoustic environment. Practices include following developmental sequences (easier sounds first), using functional vocabulary (words they need daily), and providing positive reinforcement for effort rather than just accuracy.
3. Disorder Classifications: * Articulation: Motor production issues (SODA).
   • Fluency: Flow issues (Stuttering/Cluttering).
   • Voice: Pitch/Loudness/Quality issues.
   • Language: Receptive (understanding) vs. Expressive (producing) vs. Mixed.
4. Clinical Significance: In Special Education, professionals prioritize vegetative functions first because speech is overlaid. They also understand that under physical stress (illness), the body will prioritize breathing over speaking, causing speech quality to drop.
5. Parameters & Hearing Loss: * Suprasegmentals: HI children often have flat intonation or inappropriate pitch/volume.
   • Segmentals: HI children struggle with high-frequency consonants (/s/, /f/) and often neutralize vowels into an “uh” sound because they cannot hear the subtle shifts in tongue placement.
