| 摘要 |
A linear predictive speech synthesis apparatus which receives a pitch parameter and linear predictive coefficients. The synthesis apparatus includes a device for producing an exciting source signal in response to the pitch parameter, and a device for filtering the exciting source signal in response to the linear predictive coefficients to produce a synthesized speech signal. A cascade frequency characteristic between spectral envelope frequency characteristics of the producing device and the filtering device is designated such as to correspond to a spectral envelope characteristic of an input speech signal. |
