Adapting to adverse acoustic environment in speech processing using playback training data
First Claim
Patent Images
1. A method for adapting a speech processing system with speech models trained in a first acoustic environment to a second acoustic environment, comprising:
- selecting at least a portion of original training data and playing back the selected data in the second acoustic environment to generate playback data, when the speech processing system is used in the second environment, the original training data being collected in the first acoustic environment and used to train the speech models;
recording the playback data in the second acoustic environment to generate recorded playback data; and
adapting the speech models from the first acoustic environment to the second acoustic environment based at least in part on the recorded playback data.

Abstract
An arrangement is provided for an automatic speech recognition mechanism to adapt to an adverse acoustic environment. Some of the original training data, collected from an original acoustic environment, is played back in an adverse acoustic environment. The playback data is recorded in the adverse acoustic environment to generate recorded playback data. An existing speech model is then adapted with respect to the adverse acoustic environment based on the recorded playback data and/or the original training data.
