5. Properties of Speech Sounds
Volume Pitch Quality Duration Degree of intensity tonal height of rate or speed at
or loudness a sound object, from which the sound are
high to low or low to high produced or articulated natural and distinctive tone of speech sounds , particular person yields a particular voice

6. Factors In Voice Control
Breathing Contraction and expansion of diaphragm muscles Vibration Vocal cords tighten when we start to speak. The air then has to be forced through them. This forcing set the vocal cords vibrating. Phonation Converting the air pressure from the lungs into audible vibrations is called phonation.

7. Factors In Voice Control
Resonance Resonance is the enrichment/amplification of sound. Cavities in our throat, nose, mouth, head and chest help amplify and enrich the sound produced by our vocal cords. These cavities are called resonance chambers. Articulation Human system stops, hinders or shapes the basic sound before it leaves the mouth into 44 distinct recognizable speech sounds called phonemes, for English. Articulation takes place. Lips, tongue, teeth, hard and soft palates are articulators.

8. Stages of Speech Development
**Crying in response to any stimulus (unaware) **Between sixth and seventh week (aware of the sounds) **4th month (repetition of the sounds made by himself/herself) **9th or 10th month (imitation of others without comprehension **12th-18th month (intentional use of sound patterns in meaningful ways)
