Abstract

The embodiment of the invention discloses an intelligent voice device and a control method thereof. The intelligent voice device comprises a fixed voice head and at least one movable voice head whichcan be combined with or disengaged from the intelligent voice device on the physical structure. The method includes the steps of generating a first instruction signal which makes the signal-noise ratio of voice signals picked by the movable voice heads larger than or equal to a first threshold when the movable voice heads are in an instruction input state, judging whether the signal-noise ratio ofthe voice signals picked by the movable voice heads is larger than or equal to the first threshold or not according to the first instruction signal, if yes, executing the last step, if not, executingthe next step, conducting denoising treatment on the voice signals picked by the movable voice heads so that the signal-noise ratio can be larger than or equal to the first threshold, and conductingvoice recognition on the voice signals with the signal-noise ratio larger than or equal to the first threshold. By means of the intelligent voice device, near-distance voice picking can be conducted through the movable voice heads, the voice recognition accuracy can be effectively ensured, and the intelligent voice device is simple in operation and convenient to use.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of voice control, in particular to an intelligent voice device and a control method thereof. Background technique [0002] A smart voice device is a device capable of man-machine voice interaction, including smart phones, smart home products, smart vehicle equipment, smart wearable devices, etc. For example, a smart voice device in a smart home product can interpret the picked up voice signal into a control command to control smart devices such as TVs and air conditioners. [0003] Chinese patent CN206353839U discloses a TV voice control system, including an array microphone for picking up voice signals, an audio processing chip for locating the sound source direction, and a main controller for parsing voice signals into control commands. Smart voice devices using matrix microphones such as Figure 1a As shown, the matrix microphone includes a plurality of sound heads 2, wherein th...
