Abstract

The invention discloses a far-field speech recognition model training method and device and a far-field speech recognition method and device. The far-field speech recognition model training method comprises the following steps: enabling single-channel original voice data to be subjected to multi-channel data simulation so as to obtain simulated multichannel far-field voice data; carrying out splitting and noise reduction processing on the simulated multi-channel far-field voice data; and respectively obtaining first single-channel far-field voice data and second single-channel far-field voicedata under different noise reduction parameters, and training a far-field voice recognition model by taking the first single-channel far-field voice data and the second single-channel far-field voicedata under different noise reduction parameters as training samples. The far-field speech recognition model obtained by adopting the training method provided by the invention can solve the problem ofrelatively low speech recognition rate caused by relatively long distance in a human-computer interaction process, and improves the efficiency and accuracy of far-field speech recognition in a complexenvironment.

Description

technical field [0001] The invention relates to the field of far-field speech recognition, in particular to a far-field speech recognition model training method, device, electronic equipment and storage device. The invention also relates to a far-field voice recognition method, device, electronic equipment and storage equipment. Background technique [0002] With the continuous development of artificial intelligence technology, people are more and more committed to making machines understand human speech instructions, and hope to realize the control of machines through voice, which will greatly facilitate people's production and life. In the research and exploration of voice In the process of recognition technology, various attempts and modifications have been made for the various processes of speech recognition. As a key technology of human-computer interaction, speech recognition has achieved rapid development in the past few decades, and the far-field speech recognition ...
