Coding/decoding a sampled speech signal |
摘要 |
The present invention relates to a method and to relative equipment for coding and decoding a sampled speech signal. It belongs to systems used in speech processing, in particular for compression of information. The invented method is based upon a time-frequency description and on a representation of the prototype as a fundamental period of a periodic waveform; moreover the excitation of the synthesis filter is carried out through a single, phase-adapted pulse. <IMAGE> |
