Speech sounds production

Speech sounds production

1. Three main groups

   • The Lungs
     • - it acts as power supply
     • - it provides airflow
     • -Rib cage, -Diaphragm, -Trachea
   • Larynx
     • It modulates airflow from the lungs
       • -Tongue, -False vocal cords, -Esophagus -True vocal cords
     • Sound are produced by muscles contracting.
       • Larynx Muscles produce many different modifications in the flow of air from the chest to the mouth
         • In the vocal tract the air goes through and leaves the body through the mouth and the nosetrils. the parts of the vocal tract are called ARTICULATORS.
           • ARTICULATORS
             • -Nose, -upper and lower teeth -upper and lower lips, -alveolar ridge-, hard and soft palate, -tongue, -pharynx
   • Vocal Tract
     • Oral, nasal and pharynx cavities.
     • Nasal Cavity, Palate, Lips, Epiglotis, Pharyns, Velum, Oral Cavity
     • It gives the Color to the source

2. Phonoarticulator apparatus

3. Three Categories of the sources

   • -Periodic, -Noisy, -Impulsive

4. Phone features

   • Phonetically and phonologically
     • Loudness
     • Pitch
     • Tone of voice
     • Duration and Lenght
     • Air stream mechanism
   • Physical aspects of sounds
     • Spectogram
     • Time-Waveform
