Description

technical field

[0001] Embodiments of the present invention relate to the technical field of speech processing, and in particular, to a speech recognition method and device. Background technique

[0002] Users generally use voice assistant software for voice recognition on terminal devices such as mobile phones. The process of voice recognition with software such as voice assistants is that the user starts the voice assistant software to obtain voice data; the voice data is sent to the noise reduction module for noise reduction processing; the voice data after noise reduction processing is sent to the voice recognition engine; the voice recognition engine Return the recognition result to the voice assistant; in order to reduce misjudgment, the voice assistant judges the correctness of the recognition result according to the confidence threshold, and then presents it.

[0003] At present, voice assistant software usually works relatively well in quiet environments such as of...
