Methods and apparatus for generating, updating and distributing speech recognition models
First Claim
1. A computer-implemented method comprising:
- receiving a request to update an existing speech recognition model for recognizing a particular term by a speech recognizer on a mobile device, wherein the request references a textual representation of the particular term and includes a recording of a user of the mobile device speaking the particular term or a set of features extracted from the recording, wherein the request specifies an updated speech recognition model type to be generated, and wherein the updated speech recognition type is a different speech recognition model type than the speech recognition model type of the existing speech recognition model;
generating the updated speech recognition model for recognizing the particular term based on the request; and
transmitting the updated speech recognition model for recognizing the particular term to the mobile device, as a replacement for the existing speech recognition model for recognizing the particular term.

Abstract
Techniques for generating, distributing, and using speech recognition models are described. 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. Thus, 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.

17. A non-transitory computer-readable medium storing software comprising instructions executable by one or more computers which, upon such execution, cause the one or more computers to perform operations comprising:
-
receiving a request to update an existing speech recognition model for recognizing a particular term by a speech recognizer on a mobile device, wherein the request references a textual representation of the particular term and includes a recording of a user of the mobile device speaking the particular term or a set of features extracted from the recording, wherein the request specifies an updated speech recognition model type to be generated, and wherein the updated speech recognition type is a different speech recognition model type than the speech recognition model type of the existing speech recognition model; generating the updated speech recognition model for recognizing the particular term based on the request; and transmitting the updated speech recognition model for recognizing the particular term to the mobile device, as a replacement for the existing speech recognition model for recognizing the particular term. - View Dependent Claims (18, 19)
