Abstract

In accordance with various embodiments of the disclosed subject matter, a speech detection method and a related apparatus are provided. The speech detection method includes the steps of switching a speech acquisition system from a non-trigger mode into a trigger mode according to a the first preset condition, recording a trigger mode operating reference time starting from zero, and setting a non-trigger mode operating reference time to zero; acquiring speech signals by using the speech acquisition system in the trigger mode to obtain first pulse-code modulation data; extracting the first pulse-code modulation data during the trigger mode operating reference time according to a second preset condition; and matching the first pulse-code modulation data during the trigger mode operating reference time with a speech model to obtain speech data.

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 implemented through hardware detection methods such as digital signal processing (Digital Signal Processing, DSP) chips, etc., but 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, w...
