Abstract
This invention provides a system that implements high-accuracy speech recognition while suppressing the data transfer amount between the client and server. For this purpose, the client compression-encodes speech parameters by a speech processing unit, and sends the compression-encoded speech parameters to the server. The server receives the compression-encoded speech parameters, a speech processing unit makes speech recognition of the compression-encoded speech parameters, and sends information corresponding to the speech recognition result to the client.
Claims46
A speech processing system in which speech information is input at a client side, and speech recognition is done at a server 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 compressed-encoded speech parameters, and
- said server comprising:
- reception means for receiving the compression-encoded speech parameters;
- and
- speech recognition means for making speech recognition using the speech parameters received by said reception means.
A speech processing apparatus 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 speech parameters compressed-encoded by said encoding means.
A speech processing apparatus comprising:
- reception means for receiving compression-encoded speech parameters;
- and
- speech recognition means for making speech recognition using the speech parameters received by said reception means.
A speech processing method in which speech information is input at a client side, and speech recognition is done at a server side,
- said client comprising:
- the acoustic analysis step of generating speech parameters by acoustically analyzing speech information;
- the encoding step of compression-encoding the speech parameters;
- and
- the transmission step of transmitting the compressed-encoded speech parameters, and
- said server comprising:
- the reception step of receiving the compression-encoded speech parameters;
- and
- the speech recognition step of making speech recognition using the speech parameters received in the reception step.
A speech processing method comprising:
- the acoustic analysis step of generating speech parameters by acoustically analyzing speech information;
- the encoding step of compression-encoding the speech parameters;
- and
- the transmission step of transmitting the speech parameters compressed-encoded in the encoding step.
A speech processing method comprising:
- the reception step of receiving compression-encoded speech parameters;
- and
- the speech recognition step of making speech recognition using the speech parameters received in the reception step.
