Abstract

The invention discloses a distributed microphone array pickup system and method. The voice assistant is used for picking up voice information to control equipment, the problems that an existing voiceassistant is poor in pickup effect, and resources are wasted due to the fact that the equipment is bound with a microphone pickup module and the voice assistant are solved, and the system comprises adistributed microphone array used for collecting the voice information indoors; a sound source positioning processing module which is used for positioning a sound source position where a speaker sendsout sound information; a voice processing module which is used for processing according to the sound source position and the sound information collected by the distributed microphone array; and a microphone data acquisition module which is used for acquiring signals transmitted by the distributed microphone array and synchronizing the signals transmitted by the distributed microphone array to a data acquisition terminal; The system has a good pickup effect, can control a plurality of devices through the voice information, and does not need to install an independent voice pickup module and anindependent voice assistant for each device in a matched manner, thereby reducing the resource waste.

Description

technical field [0001] The invention relates to the technical field of speech recognition, in particular to a distributed microphone array sound pickup system and method. Background technique [0002] With the development of artificial intelligence technology, the technology of controlling equipment through human-computer interaction is becoming more and more common. In human-computer interaction technology, the technology of controlling equipment through voice has been widely used. In smart homes, etc. In application scenarios, voice assistants have almost become a standard configuration for future development. [0003] However, it is not easy for a device to have a human-like hearing ability. In addition to the back-end speech recognition, semantic understanding and many other links, the first step is to allow the device to obtain clear voice signals, that is, to allow the device to hear more clearly. [0004] The existing devices are equipped with voice assistants, the i...
