| Abstract(in English) | Computational models of speech production are explained with the electrical equivalent circuit representation. One-dimensional acoustic tube is well-known approximation of vocal tracts under the assumption of the plane wave propagation, and is electrically represented by transmission line. For the purpose of the extension of the vocal-tract models, three-dimensional acoustic field is represented in terms of both plane waves and higher-order modes in tubes which can be also represented by electrical circuits. This model is constructed using an asymmetrically connected structure of rectangular acoustic tubes, and can parametrically represent acoustic characteristics in higher frequencies where the assumption of the plane wave propagation does not hold. Computational results show the appearance of zeros in the transfer characteristics even the vocal tract does not include any branch in its geometrical configuration. |
