摘要

PROBLEM TO BE SOLVED: To provide a method for transmitting and receiving a speech feature quantity vector between a client and a server without generating a code book again by changing a compressing method for the speech feature quantity vector according to parameters of a sound model in use and, further, change in kind of the speech feature quantity in use.;SOLUTION: In the client/server speech recognizing method, a speech compression coefficient is calculated from the sound model used by a server computer 200 for speech recognition, and the speech compression coefficient and a speech analysis condition for extracting a speech feature quantity vector are transmitted to a client computer 100. The client computer extracts a speech feature quantity vector from an input speech based upon the received speech analysis condition, compresses the speech feature quantity vector based upon the speech compression coefficient, and transmits the compressed speech feature quantity vector to the server computer. The server computer restores the compressed speech feature quantity vector received from the client computer based upon the speech compression coefficient and performs speech recognition by using the restored speech feature quantity vector.;COPYRIGHT: (C)2007,JPO&INPIT
