(engineering acoustics)
Production of speech sounds.
Any sound mace during speech.



in phonetics, the physical process of forming audible speech sounds. Phonation, the combined activity of the vocal apparatus, results in articulation. The term also designates the acoustic features of a sound that result in its aural perception and analysis. The production and perception of sounds interact in accordance with the principle of feedback. In the formation of a sound, the speaker’s acoustic regulation plays an important role, and in the perception of a sound, acoustic (sensory) analysis is supplemented by the listener’s internal articulatory (motor) regulation; that is, by analysis through synthesis.

No inspiratory abduction on either side was observed, but there was phonatory adduction of the left vocal fold, and with deep inspiration there was some paradoxic adduction of the right vocal fold.
A phonatory gap could be seen on adduction; this gap was reflective of poor vocal fold movement secondary to an increase in vocal fold mass and stiffness.
