Abstract

The embodiment of the invention relates to a method and apparatus for determining the position of a microphone array, a device and a computer readable storage medium. The method comprises the following steps: determining a candidate position set of the microphone array at a voice interaction device; determining signal transmission characteristics between the microphone array arranged at a candidate position in the candidate position set and a loudspeaker of the voice interaction device; and based on the signal transmission characteristics, determining a target position for arranging the microphone array in the candidate position set. Therefore, the target position of the microphone array is determined according to the signal transmission characteristics between the microphone array and theloudspeaker, so that when the microphone array is arranged at the target position, the signal transmission characteristics with the loudspeaker are the optimal, the voice wake-up and voice recognition effects can be improved, and better user experience can also be brought.

Description

technical field [0001] Embodiments of the present disclosure relate to the field of intelligent interaction, and more particularly to a method, device, device and computer-readable storage medium for determining the position of a microphone array of a voice interaction device. Background technique [0002] Intelligent interactive devices, especially voice interactive devices, have been widely used in people's daily life, work, and even production processes. For example, as an important application in voice interaction devices, smart speakers with voice interaction functions greatly facilitate people's lives due to their wide range of applications. [0003] A voice interaction device includes a microphone array (or a single microphone) and a loudspeaker. When the voice interaction device is working, the signal transmission characteristics (such as distortion, frequency response fluctuation, etc.) between its microphone array and the speaker will affect the effect of voice wa...
