Sound source positioning method of intelligent sound box, intelligent sound box and computer readable medium

Abstract

The present invention provides a sound source positioning method of an intelligent sound box, the intelligent sound box and a computer readable medium, wherein the method comprises the steps of obtaining a first voice signal carrying a preset awakening word, sent by a target sound source and received by at least two sets of signal reception modules on the intelligent sound box if the situation ofneeding to acquire the voice signal sent out by the target sound source is determined; obtaining the time difference of the two signal reception modules in each signal reception module pair for receiving the first voice signal; according to the first voice signal and the time difference of each signal reception module pair for receiving the first voice signal, determining the orientation of the target sound source sending out the first voice signal. According to the technical scheme of the present invention, the target sound source can be positioned on a scene of more sound sources, so that the intelligent sound box can only acquire the voice signal of the target sound source in the positioned direction, and further provide the services to a user corresponding to the target sound source. Moreover, the functions of the intelligent sound box also can be enriched effectively, so that the intelligent sound box is more flexible and convenient to use.

Description

【Technical field】 [0001] The invention relates to the technical field of computer applications, in particular to a sound source localization method for a smart speaker, a smart speaker and a computer-readable medium. 【Background technique】 [0002] With the development of science and technology, smart devices gradually enter users' homes, forming an intelligent furniture environment. For example, smart speakers, as an intelligent device in smart homes, can help users check music, weather, chat, dialogue, etc., so smart speakers need to have voice recognition, semantic analysis, content services, speech generation, voice TTS ( TextToSpeech; TTS) broadcast feedback and other functions. [0003] In the prior art, the smart speakers are all provided with a default wake-up word, and the smart speakers can be in a dormant state when not working. When the user needs to start the smart speaker, he can call the wake-up word of the smart speaker through voice, and the smart speaker ...

Problems solved by technology

[0004] However, in the prior art, the smart speaker cannot locate the sound source. If multiple users around the smart speaker call the smart speaker at the same time, the multiple users are equivalent to multiple sound sources, which will cause confusion in the work of the smart speaker and cannot be realized.
