The voice recognition device applied to the robot comprises distributed microphone arrays and a voice processor, wherein the distributed microphone arrays include a first microphone array located on the front surface of the robot and a second microphone array located on the back surface of the robot, and are used for acquiring a first voice signal and a second voice signal respectively; and the voice processor is used for fusing the first voice signal and the second voice signal to perform voice recognition.

Description

technical field [0001] The present disclosure relates to the field of speech processing, and in particular, to a robot and its speech recognition device and method. Background technique [0002] Currently, a single-mic, linear microphone is usually mounted on a robot for speech recognition. However, when the robot is applied to environments such as exhibitions and business halls, the accuracy of speech recognition is poor because the environment is noisy and the robot is constantly moving. Contents of the invention [0003] The purpose of the present disclosure is to provide a robot and its voice recognition device and method, which can accurately perform voice recognition in various scenarios. [0004] According to a first embodiment of the present disclosure, there is provided a speech recognition device applied to a robot, comprising: a distributed microphone array, the distributed microphone array includes a first microphone array located on the front of the robot and...
