Estimation of excitation parameters. |
摘要 |
<p>Speech is encoded by analyzing a digitized speech signal to determine excitation parameters for the digitized speech signal. The digitized speech signal is divided into at least two frequency bands. A nonlinear operation is performed on at least one of the frequency bands to produce a modified frequency band. A determination is made as to whether the modified frequency band is voiced or unvoiced.</p> |
