Finding the shape of a human vocal tract from speech sounds.

Ponente(s): Tuncay Aktosun .

The elementary units for human speech are known as phonemes, and the utterance of each phoneme is governed by a particular shape of the human vocal tract. In this talk, a mathematical description is presented for the shape of the vocal tract during the creation of each phoneme, which corresponds to a direct problem. Then, a corresponding inverse problem is analyzed; namely, the determination of the shape of the human vocal tract from the measurement of sound pressure associated with an uttered phoneme.
