The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.



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.
