Beam information arrival direction determination method and device, and storage medium

Abstract

The invention provides a beam information arrival direction determination method and a device and a storage medium, and the method comprises the steps: determining the target beam information of a to-be-tracked object according to an array formed by a plurality of microphones and the target voice information of the to-be-tracked object; determining direction response power of the target beam information in each preset direction according to the target beam information, an array structure formed by a plurality of microphones and a wave velocity forming algorithm; and determining the preset direction corresponding to the maximum direction response power as the direction of arrival. The direction response power is determined through the array structure formed by the microphones, the wave velocity forming algorithm and the target wave beam information determined according to the target voice information, the arrival direction is determined according to the maximum direction response power,and the direction of the speaker can be automatically tracked according to the arrival direction. The accuracy of determining the position of the sound source is improved, so that a speaker can stillkeep the output effect of the microphone sound under the condition of changing the speaking direction.

Description

technical field [0001] The present application relates to the technical field of voice information, in particular to a method, device and storage medium for determining the direction of arrival of beam information. Background technique [0002] The microphone is a widely used sound collection device, and the microphone array is a sound collection system formed by arranging and combining multiple microphones in a certain shape. The microphone array can collect multi-channel speech with spatial information, and then carry out speech enhancement. The beamforming can only process the direction where the steering vector is located, and the effect in other directions will be attenuated to a certain extent or even the voice cannot be collected. If the speaker is constantly moving, the current microphone arrays on the market cannot accurately query the position of the speaker according to the change of the speaker's speaking position, which greatly reduces the accuracy of determinin...

[0002] The microphone is a widely used sound collection device, and the microphone array is a sound collection system formed by arranging and combining multiple microphones in a certain shape. The microphone array can collect multi-channel speech with spatial information, and then carry out speech enhancement. The beamforming can only process the direction where the steering vector is located, and the effect in other directions will be attenuated to a certain extent or even the voice cannot be collected

If the speaker is constantly moving, the current microphone arrays on the market cannot accurately query the position of the speaker according to the change of the speaker's speaking position, which greatly reduces the accuracy of determining the position of the sound source. Resulting in a poorer effect of enhancing the voice of the speaker's position
