Abstract: Methods are disclosed for identifying possible errors made by a speech recognition system without using a transcript of words input to the system. A method for model adaptation for a speech recognition system includes determining an error rate, corresponding to either recognition of instances of a word or recognition of instances of various words, without using a transcript of words input to the system. The method may further include adjusting an adaptation, of the model for the word or various models for the various words, based on the error rate. Apparatus are disclosed for identifying possible errors made by a speech recognition system without using a transcript of words input to the system. An apparatus for model adaptation for a speech recognition system includes a processor adapted to estimate an error rate, corresponding to either recognition of instances of a word or recognition of instances of various words, without using a transcript of words input to the system. The apparatus may further include a controller adapted to adjust an adaptation of the model for the word or various models for the various words, based on the error rate.

Abstract: A system directs boom microphone placement. A microphone is configured to capture speech audio from a user and output corresponding electrical signals. A proximity sensor is situated adjacent the microphone and configured to produce output signals representative of a distance from the microphone to the user's face or mouth. A headset assembly includes a boom carrying the microphone and the proximity sensor, where the boom can be adjusted to a plurality of positions adjacent the user's face or mouth. Processing circuitry is coupled to receive the output signals from the proximity sensor and produce an output indicative that the microphone is outside a prescribed distance or range of distances from the user's face or mouth.
