Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for enhancing speech recognition accuracy. In one aspect, a method includes receiving an audio signal that corresponds to an utterance recorded by a mobile device, determining a geographic location associated with the mobile device, adapting one or more acoustic models for the geographic location, and performing speech recognition on the audio signal using the one or more acoustic models model that are adapted for the geographic location.
Claims20
A system comprising:
- one or more computers;
- and
- one or more computer-readable media coupled to the one or more computers having instructions stored thereon which, when executed by the one or more computers, cause the one or more computers to perform operations comprising:
- receiving an audio signal that corresponds to an utterance recorded by a mobile device,
- determining a geographic location associated with the mobile device,
- adapting one or more acoustic models for the geographic location, and
- performing speech recognition on the audio signal using the one or more acoustic models model that are adapted for the geographic location.
One or more computer storage media encoded with a computer program, the program comprising instructions that when executed by one or more computers cause the one or more computers to perform operations comprising:
- receiving an audio signal that corresponds to an utterance recorded by a mobile device;
- determining a geographic location associated with the mobile device;
- adapting one or more acoustic models for the geographic location;
- and
- performing speech recognition on the audio signal using the one or more acoustic models model that are adapted for the geographic location.
A computer-implemented method comprising:
- receiving an audio signal that corresponds to an utterance recorded by a mobile device;
- determining a geographic location associated with the mobile device;
- adapting one or more acoustic models for the geographic location;
- and
- performing speech recognition on the audio signal using the one or more acoustic models model that are adapted for the geographic location.
