| Popis: | A pulse train of primary pulses is estimated from an inverse LPC analysis of a frame of voiced speech. From this estimated pulse train a pole-zero filter is estimated. The estimated pulse train is used to excite the estimated pole-zero filter to produce a synthesized speech signal. The synthesized speech signal is compared to the original frame of speech to determine the error in the original speech signal. Both the pulse amplitude and filter are adjusted to compensate for the error and another synthesized speech signal is produced. The process may be repeated until the synthesized speech signal and original speech signal converge. |
