US 8,135,589 B1 · Performing speech recognition over a network and using speech recognition results

Abstract

Systems, methods and apparatus for generating, distributing, and using speech recognition models. A shared speech processing facility is used to support speech recognition for a wide variety of devices with limited capabilities including business computer systems, personal data assistants, etc., which are coupled to the speech processing facility via a communications channel, e.g., the Internet. Devices with audio capture capability record and transmit to the speech processing facility, via the Internet, digitized speech and receive speech processing services, e.g., speech recognition model generation and/or speech recognition services, in response. The Internet is used to return speech recognition models and/or information identifying recognized words or phrases. The speech processing facility can be used to provide speech recognition capabilities to devices without such capabilities and/or to augment a device's speech processing capability. Voice dialing, telephone control and/or other services are provided by the speech processing facility in response to speech recognition results.

Dependent claims

A system comprising:

one or more computers;
and
one or more non-transitory storage devices storing instructions that, when executed by the one or more computers cause the one or more computers to perform operations comprising
receiving service requests comprising new model generation requests and model update requests, wherein each service request is associated with speech data;
for each service request, generating a speech recognition model corresponding to the service request in response to receiving the service request and associated speech data;
maintaining a training database of speech samples, wherein maintaining the training database comprises augmenting the training database with speech data associated with each received service request;
and
maintaining a model store of generated speech recognition models, wherein maintaining the model store comprises storing generated speech recognition models.

5 more elements

A computer program product, stored on a non-transitory computer readable medium, comprising instructions that when executed on one or more computers cause the one or more computers to perform operations implementing a speech recognition model training service, the operations comprising:

receiving service requests comprising new model generation requests and model update requests, wherein each service request is associated with speech data;
for each received service request, generating a speech recognition model corresponding to the service request in response to receiving the service request and associated speech data;
maintaining a training database of speech samples, wherein maintaining the training database comprises augmenting the training database with speech data associated with each received service request;
and
maintaining a model store of generated speech recognition models, wherein maintaining the model store comprises storing generated speech recognition models.
