Abstract:
A speech processing system in which speech information is input at a client side, and speech recognition is done at a serve side,said client comprising: acoustic analysis means for generating speech parameters by acoustically analyzing speech information; encoding means for compression-encoding the speech parameters; and transmission means for transmitting the compression-encoded speech parameters, and said server comprising: reception means for receiving the compression-encoded speech parameters; first computation means for computing output probabilities of states of acoustic models, as first likelihood, using the compression-encoded speech parameters received by said reception means; selection means for selecting states of acoustic models using only the first likelihood; decoding means for decoding the compression-encoded speech parameters received by said reception means; second computation means for computing output probabilities of states of acoustic models selected by said selection means, as second likelihood, using the decoded speech parameters; and speech recognition means for making speech recognition using the second likelihood obtained by said second computation means.
