Abstract
System and techniques for automatic speech recognition de-reverberation are described herein. A portion of an audio stream may be obtained. here, the portion of the audio stream is a proper subset of the audio stream. A filter may be created by applying Generalized Weighted Prediction Error (GWPE) to the portion of the audio stream. The filter may be applied to the audio stream to remove reverberation. The filtered version of the audio stream may then be provided to an audio stream consumer.
Claims24
A system for automatic speech recognition de-reverberation, the system comprising:
- a sampler to obtain a portion of an audio stream, the portion of the audio stream being a proper subset of the audio stream;
- a signal processor to create a filter by applying Generalized Weighted Prediction Error (GWPE) to the portion of the audio stream;
- a multiplexer to apply the filter to the audio stream to remove reverberation;
- and
- an interlink to provide a filtered version of the audio stream to an audio stream consumer.
At least one machine readable medium including instructions for automatic speech recognition de-reverberation, the instructions, when executed by a machine, cause the machine to perform operations comprising:
- obtaining a portion of an audio stream, the portion of the audio stream being a proper subset of the audio stream;
- creating a filter by applying Generalized Weighted Prediction Error (GWPE) to the portion of the audio stream;
- applying the filter to the audio stream to remove reverberation;
- and
- providing a filtered version of the audio stream to an audio stream consumer.
A method for automatic speech recognition de-reverberation, the method comprising:
- obtaining a portion of an audio stream, the portion of the audio stream being a proper subset of the audio stream;
- creating a filter by applying Generalized Weighted Prediction Error (GWPE) to the portion of the audio stream;
- applying the filter to the audio stream to remove reverberation;
- and
- providing a filtered version of the audio stream to an audio stream consumer.
