System and method for updating an adaptive speech recognition model
First Claim
1. A machine-implemented method, comprising:
- determining that a first user of a first mobile communication device is engaged in a call over a communications network;
providing an adaptive speech recognition model comprising a speaker-dependent speech recognition model;
after providing the adaptive speech recognition model, analyzing an outbound audio channel of a baseband unit of the first mobile communication device to obtain a call audio signal corresponding to audio input from one or more microphones of the first mobile communication device; and
updating the adaptive speech recognition model with training data derived from the call audio signal.

Abstract
A method for updating an adaptive speech recognition model is provided. In some implementations, the method is performed at a communications device including one or more processors and memory storing instructions for execution by the one or more processors. The method includes determining that a first user of a first mobile communication device is engaged in a call over a communications network and providing an adaptive speech recognition model The method also includes analyzing an outbound audio channel of the first mobile communication device to obtain a call audio signal corresponding to audio input from one or more microphones of the first mobile communication device and updating the adaptive speech recognition model with training data derived from the call audio signal.

25. An electronic device, comprising:
-
one or more microphones; one or more processors; and memory storing one or more programs, the one or more programs comprising instructions, which when executed by the one or more processors, cause the one or more processors to; determine that a user is engaged in a call over a communications network; analyze an outbound audio channel of a baseband unit of the electronic device to obtain a call audio signal corresponding to audio input from the one or more microphones; determine whether a speaker-dependent speech recognition model corresponding to the user is stored in the memory; and in response to determining that a speaker-dependent speech recognition model corresponding to the user is stored in the memory, update the speaker-dependent speech recognition model with training data derived from the call audio signal. - View Dependent Claims (26)
