音声認識方法、装置、機器及びコンピュータ読み取り可能な記憶媒体
Document Type and Number:
Japanese Patent JP7434137
Kind Code:
B2
Abstract:
The disclosure provides a speech recognition method, a device and a computer-readable storage medium. The method includes obtaining a first voice signal collected from a first microphone in a microphone array and a second voice signal collected from a second microphone in the microphone array, the microphone array including at least two microphones, such as two, three or six microphones. The method further includes extracting enhanced features associated with the first voice signal and the second voice signal through a neural network, and obtaining a speech recognition result based on the enhanced features extracted.
