Abstract

The present invention provides a speech detection method and a device. According to a preset judgment condition, the speech capture and speech extraction are carried out, the existence of speech data input triggering can be judged through a software algorithm, and after speech data input and output triggering is detected, the ending of speech input is judged through the software algorithm. According to the method, the form of software is used to substitute a e traditional hardware DSP chip to realize the speech detection, the hardware cost can be effectively reduced while the detection performance is not reduced, and the system consumption is decreased for some extent.

Description

technical field [0001] The invention relates to voice detection technology, in particular to a voice detection method and device. Background technique [0002] With the continuous development of smart home technology, voice control is increasingly used in people's home life, for example, controlling household appliances by voice. Accurate voice detection is an important prerequisite for effective voice control. [0003] At present, voice detection is generally realized through hardware detection methods such as digital signal processing (Digital Signal Processing, DSP for short) chips. The implementation cost of this hardware detection method is relatively large, and the system power consumption of the entire control system is also relatively large. Contents of the invention [0004] The embodiment of the present invention provides a voice detection method and device, which replaces the traditional hardware DSP chip to realize voice detection in the form of software, whic...
