Methods and apparatus for generating, updating and distributing speech recognition models
First Claim
1. A computer-implemented method comprising:
- receiving, by a speech recognition model training system and from a first computing device, (i) a request for an update to a speaker-dependent speech recognition model associated with the first computing device, and (ii) recorded speech;
generating, based on processing the recorded speech from the first computing device and by the speech recognition model training system, the update to the speaker-dependent speech recognition model associated with the first computing device;
generating, based on processing the recorded speech from the first computing device and by the speech recognition model training system, an update for a speaker-independent speech recognition model associated with a second computing device;
transmitting, based on receiving the request and by the speech recognition model training system, the update to the speaker-dependent speech recognition model to the first computing device;
determining, by the speech recognition model training system, that a predetermined period of time has elapsed since the speaker-independent speech recognition model associated with the second computing device was last updated; and
transmitting, based on determining that the predetermined period of time has elapsed since the speaker-independent speech recognition model associated with the second computing device was last updated and by the speech recognition model training system, the update to the speaker-independent speech recognition model to the second computing device.

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.
