Articulatory

In the case of oral languages there are three basic areas of study: * Articulatory phonetics : the study of the production of speech sounds by the articulatory and vocal tract by the speaker.

Phonetics deals with the articulatory and acoustic properties of speech sounds, how they are produced, and how they are perceived.

Place of articulation (active) The articulatory gesture of the active place of articulation involves the more mobile part of the vocal tract, typically some part of the tongue or lips.

Semivowels main Some approximants resemble vowels in acoustic and articulatory properties and the terms semivowel and glide are often used for these non-syllabic vowel-like segments.

There is evidence that people who stutter activate motor programs before the articulatory or linguistic processing is initiated.

The system, first marketed in 1994, provides full articulatory-based text-to-speech conversion using a waveguide or transmission-line analog of the human oral and nasal tracts controlled by Carré's "distinctive region model".

Until recently, articulatory synthesis models have not been incorporated into commercial speech synthesis systems.
