Phonation - Voicing
A voiced sound is produced when air expelled from the lungs causes the vocal cords to vibrate. This produces a fundamental tone accompanied by several non-harmonic overtones. The resulting sound is modified by movements in the vocal tract, by the volume of the airflow and by the degree of constriction of the vocal cords. (During speech the flow of air is relatively small because of constrictions of the vocal cords.) Vowels are usually voiced, as are many consonants. (see voiced consonant.)
If the vocal cords are lax and do not vibrate, then the sound (usually a consonant) is voiceless.
The vocal vibration is varied to produce intonation and tone. This is accomplished by varying the pressure of the air column under the glottis as well as the tension in the vocal cords themselves. These cause changes in the frequency of vocal-cord vibration, which generates the fundamental pitch of the voice. Tone and intonation are not conveyed well by voiceless sounds, with their lax vocal cords, but the changes in airflow are still audible.
