Speech control method and system based on multiple microphones, microphones and server

Abstract

The invention discloses a speech control method and system based on multiple microphones, the microphones and a server. The method comprises following steps that the server receives sound informationin a region collected by the multiple microphones in different position of the same region; the server analyzes the sound information of the microphones so as to extract speech instruction informationof a user; the server determines to-be-controlled household electrical appliances and instruction information corresponding to the household electrical appliances according to the speech instructioninformation of the user; and the server sends the instruction information of the household electrical appliances to the household electrical appliances so as to control the household electrical appliances to execute corresponding operation. According to the invention, by collecting sound information in the same region through the microphones, and analyzing the sound information of the microphonesso as to extract effective speech instruction information, interfering noise is effectively restrained, speech recognition rate is increased, there is no need to set specific parameters according to specific environments and following maintenance cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular to a multi-microphone-based voice control method and system, a microphone and a server. Background technique [0002] With the development of the smart product industry, voice command control is familiar to people. Voice command control can provide users with a more humanized experience. [0003] Most of the existing solutions for voice command control of smart products on the market are to embed a microphone on the smart product and then perform voice recognition. The technology generally used is near-field or far-field voice recognition technology. However, speech recognition has higher requirements on the environment, and environmental noise and echoes in the regional space will affect the quality of speech recognition. [0004] In related technologies, configuring specific parameters for a specific environment alleviates the problem of low speech recognition rate t...

Problems solved by technology

However, speech recognition has high requirements on the environment. Environmental noise and echo in the regional space will affect the quality of speech recognition.

[0004] In related technologies, configuring specific parameters for a specific environment alleviates the problem of low speech recognition rate to a certain extent, but at the same time it also brings a technical problem of "the environment changes, and the parameters must change at any time", which leads to later maintenance. greatly increased cost
