Method and Apparatus for Determining a Motion Environment Profile to Adapt Voice Recognition Processing
First Claim
1. A method performed by a device for adapting 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;
determining a motion profile for the device;
determining a temperature profile for the device;
determining a noise profile for the acoustic signal;
determining, from the motion, temperature, and noise profiles, a motion environment profile for the device; and
adapting voice recognition processing for the speech signal based on the motion environment profile.

Abstract
A method and apparatus for determining a motion environment profile to adapt voice recognition processing includes a device receiving an acoustic signal including a speech signal, which is provided to a voice recognition module. The method also includes determining a motion profile for the device, determining a temperature profile for the device, and determining a noise profile for the acoustic signal. The method further includes determining, from the motion, temperature, and noise profiles, a motion environment profile for the device and adapting voice recognition processing for the speech signal based on the motion environment profile.
