Patent ID: 7058580

Claim:
A speech processing system in which speech information is input at a client side, and speech recognition is performed at a server side, said client comprising: encoding means for compression-encoding the speech information; and transmission means for transmitting the compressed-encoded speech information, and said server comprising: reception means for receiving the compression-encoded speech information; first computation means for computing output probabilities of states of acoustic models, as first likelihood, using the compression-encoded speech information received by said reception means; selection means for selecting states of acoustic models using the first likelihood; decoding means for decoding the compression-encoded speech information 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 information; speech recognition means for accomplishing speech recognition using the second likelihood obtained by said second computation means; execution means for executing a predetermined application program based on a recognition result of said speech recognition means; and transmission means for transmitting, to said client, a result obtained from the predetermined application program executed by said execution means.
