Abstract
If an adaptation is made taking into consideration the noise produced in a specific operating mode of a device in a case where the noise environment changes, a decline in recognition rate is expected during operation of the device in a mode for which no adaptation is made. Accordingly, the present operating mode of the device is detected, the name of data for speech recognition corresponding to the operating mode of the device is retrieved from a table that describes data for speech recognition, the retrieved data for speech recognition corresponding to the operating mode of the device is set and speech recognition processing is executed based upon the set data.
Claims15
A speech recognition apparatus comprising:
- an input section arranged to input speech;
- a detector arranged to detect the present operating mode of a device;
- an instructor arranged to search a memory in which has been stored information indicating a corresponding relationship between the operating mode of the device and data for speech recognition, and to issue an instruction indicative of data for speech recognition, which has been retrieved from the memory, corresponding to the operating mode of the device;
- and
- a recognition section arranged to recognize the input speech using the data for speech recognition indicated by the instruction from said instructor.
A speech recognition method comprising the steps of:
- inputting speech;
- detecting the present operating mode of a device;
- searching a memory in which has been stored information indicating a corresponding relationship between the operating mode of the device and data for speech recognition, and issuing an instruction indicative of data for speech recognition, which has been retrieved from the memory, corresponding to the operating mode of the device;
- and
- recognizing the input speech using the data for speech recognition indicated by the instruction.
A computer program product storing a computer-readable medium comprising a computer program code for a speech recognition method, said method comprising the steps of:
- inputting speech;
- detecting the present operating mode of a device;
- searching a memory in which has been stored information indicating a corresponding relationship between the operating mode of the device and data for speech recognition, and issuing an instruction indicative of data for speech recognition, which has been retrieved from the memory, corresponding to the operating mode of the device;
- and
- recognizing the input speech using the data for speech recognition indicated by the instruction.
