The invention discloses a meeting window call
system based on a voice sensor, and relates to the technical field of communication. Comprising a full-space voice acquisition module, a dynamic confidence evaluation module, a
phase coupling enhancement module, a multi-dimensional speech mode recognition module, a dynamic
gain adjustment and tone
quality enhancement module and a full-link voice integrity
verification module, an array type voice sensing unit is deployed based on audio reflection characteristics, a multi-band full-space acquisition matrix is constructed, voice signals of two parties meeting are acquired, and a basic audio
data stream with a high
signal-to-
noise ratio is output. According to the invention, through array sensing acquisition, dynamic confidence evaluation,
phase coupling and
harmonic enhancement, multi-dimensional
speech recognition and dynamic
gain adjustment, accurate recognition and fidelity enhancement of low-volume speech are realized, and through combination of full-link integrity
verification and mistaken killing
backtracking, weak signals are ensured not to be missed and distorted, so that the accuracy of
speech recognition is improved. And the privacy, the security and the information integrity of the meeting call are improved.
