EXTRACTING FEATURES FROM SPEECH SIGNAL |
摘要 |
A polyphase digital filterbank extracts a spectral envelope composed of thirty-two bands, having uniform bandwidths, from a speech signal. The spectral envelope is then compressed into a predetermined number of bands having uniform bandwidths. Spectral energy features are extracted from the compressed envelope and are utilized to form templates representing the speech signal. |
