Embodiment Construction
[0039] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0040] In the embodiment of the present invention, the execution subject of the process may be a mobile terminal that performs human-computer interaction through voice recognition, for example, a smart speaker. Generally, the mobile terminal includes the following four modules: a microphone array, a main control module, a loudspeaker module and a radio frequency communication module.

The invention belongs to the technical field of smart loudspeakers and provides a voice interaction method and device. According to the voice interaction method and device, a microphone array is controlled to pick up voice in all directions in a real-time manner; the sound source directions of each sound source in the voice are acquired according to a microphone array algorithm, whether a certainsound source direction is a noise direction is judged; if the sound source direction is the noise direction, noise signals in the direction are filtered out; and the voice from which the noise signalsare filtered out is further recognized; corresponding operation is performed based on a recognition result; and therefore, the problem of voice interference which is brought about during the coexistence of a smart device and other voice playback devices in the prior art can be solved, a signal-to-noise ratio and a wake-up success rate are improved, system power consumption can be reduced, and theeffect of human-machine voice interaction can be improved.
Description
technical field [0001] The invention belongs to the technical field of intelligent speakers, and in particular relates to a voice interaction method and device. Background technique [0002] With the popularity of speakers, users have higher and higher requirements for the intelligence of speakers. Traditional speakers can only play sound, and smart speakers add a recording module to the traditional speakers, thus realizing human-computer voice interaction. Users can control the smart speaker through voice to realize functions such as ordering songs, checking the weather, and turning on the air conditioner. Smart speakers have gradually entered the living room of ordinary people, becoming an important part of the living room together with the TV. [0003] In daily life, there may always be sound sources from other voice playback devices during the use of smart speakers. However, the existing technology of smart speakers can only collect all the sounds, and cannot shield ot...
