Method and Apparatus for Adjusting Trigger Parameters for Voice Recognition Processing Based on Noise Characteristics
First Claim
1. A method performed by a device for adjusting a trigger parameter related to voice recognition processing, the method comprising:
- receiving into the device an acoustic signal comprising a speech signal, which is provided to a voice recognition module, and comprising noise;
determining a noise profile for the acoustic signal, wherein the noise profile identifies a noise level for the noise and identifies a noise type for the noise; and
adjusting the voice recognition module based on the noise profile by adjusting a trigger parameter related to voice recognition processing.

Abstract
A method and apparatus for adjusting a trigger parameter related to voice recognition processing includes receiving into the device an acoustic signal comprising a speech signal, which is provided to a voice recognition module, and comprising noise. The method further includes determining a noise profile for the acoustic signal, wherein the noise profile identifies a noise level for the noise and identifies a noise type for the noise based on a frequency spectrum for the noise, and adjusting the voice recognition module based on the noise profile by adjusting a trigger parameter related to voice recognition processing.

22. A device configured to perform voice recognition, the device comprising:
-
at least one acoustic transducer configured to receive an acoustic signal comprising a speech signal and noise; a voice-recognition module configured to perform voice recognition processing on the speech signal; and a processing element configured to; determine a noise profile for the acoustic signal, wherein the noise profile identifies a level and stationarity of the noise; and adjust the voice recognition module by adjusting a trigger threshold related to voice recognition based on the noise profile, wherein the trigger threshold comprises at least one of a trigger threshold for phoneme detection, a trigger threshold for phrase matching, or a trigger for speaker verification. - View Dependent Claims (23)
