phonation

n. production of vocal sounds

In phonetics, phonation is the "use of the laryngeal system to generate an audible source of acoustic energy, i.e., sound, which can then be modified by the articulatory actions of the rest of the vocal apparatus." Phonation has traditionally been seen as one dimension of phonetic voicing, the degree of glottal tension. (A second dimension of voicing is timing, called voice onset time, or "VOT". When a sound is described as "half voiced", it may not be clear whether it is quality (phonation) or quantity (VOT) that is referred to.)
