Abstract
A method of operating a speech recognition system includes converting a spoken utterance by a user into an electrical voice signal by use of a local microphone associated with a local electronic device. The electrical voice signal is transmitted to a remote voice recognizer. The remote voice recognizer is used to transcribe the electrical voice signal and to produce a confidence score. The confidence score indicates a level of confidence that the transcription of the electrical voice signal substantially matches the words of the spoken utterance. The transcription of the electrical voice signal and the confidence score are transmitted from the remote voice recognizer to the local electronic device. The electrical voice signal, the transcription of the electrical voice signal, and the confidence score are used at the local device to train a local voice recognizer.
