Voice recognition control method and device

Abstract

The invention relates to a voice recognition control method and device. The voice recognition control method is applied to a voice recognition control device. The method comprises the following stepsof sensing current sound vibration information and / or motion behavior information of a user through a sensing unit; carrying out calculation processing on the sensed current sound vibration information and / or the motion behavior information by adopting a preset algorithm; obtaining the characteristic information corresponding to the current sound vibration information based on the calculation processing result; outputting a command control signal according to the characteristic information. According to the method and the device, under the condition that the content of the sound or the voiceprint waveform is not required to be judged, only the sound vibration information sensed by the sensing unit and the motion behavior information are processed, and the characteristic information of starting to speak of the user is identified according to the processing result; the technical difficulty, the cost and the power consumption are reduced, and the stability is improved; the other differentnoise eliminating mode is adopted to the maximum degree, the voice other than the user is completely isolated and filtered, and the capability of accurately judging the voice of the user is improved.

Therefore, this patent is quite different from the sound wave recognition master. Apple's patent uses an acceleration sensor for detection. Recognizing voice users with microphone voice information is the closest technology at present. It is complete and comprehensive, but the identification technology is complicated, and it is not easy to popularize and promote.
