Activated voiceprint password security control method and system under public background noises

Abstract

The invention discloses an activated voiceprint password security control method and system under public background noise. The steps of the method include: activating a recognition module to perform real-time voice monitoring in a common environment, and determining whether a voice signal needs to activate a sound source location pickup module; The sound source localization pickup module receives the sound source data of the interactive target, and estimates the time delay difference of arrival; for the time delay difference of arrival, multiple hyperboloids are constructed in combination with the position of the microphone array to determine the position of the sound source of the interactive target, and obtain the sound source of the interactive target The voice signal of the source; the preprocessing module preprocesses the voice signal of the interactive target sound source; the voiceprint password recognition module extracts the characteristic parameters of the voice signal, and matches the characteristic parameters with the instruction text of the recording library. The present invention solves the power consumption of the system, locates and picks up the increment of the voice burst under the low signal-to-noise ratio of other human voices, echoes, and reverberations, and solves the above-mentioned current problems through three safe voice recognition and control operations.

Description

Activation-type voiceprint password security control method and system under public background noise technical field The invention relates to the technical field of human-computer interaction of smart home, in particular to an activated voiceprint password security control method and system under public background noise. Background technique With the development of society, voice as a medium appears in the human-computer interaction interface, which is the trend of social development. Compared with any other communication method between people, voice communication is a fast means , Speech recognition has gradually penetrated into our daily life, and now many industry pioneers believe that the interaction between man and machine through speech will lead to a convenient people's daily life. Automatic Speech Recognition (ASR) technology has been the subject of research since the 1950s. Automatic speech recognition technology is a technology that converts human speech into t...
