Abstract

The invention discloses a speech recognition method. The method comprises: acquiring first speech data and a corresponding first lip video, and segmenting the first speech data to obtain correspondinginitials and finals; recognizing the initials and finals through a trained speech recognition model to obtain a corresponding speech recognition result, and detecting whether the speech recognition result has a small probability initial and / or a small probability final of which the recognition probability is smaller than a preset threshold; if yes, acquiring a first lip image sequence corresponding to the small probability initial and / or the small probability final from the first lip video, and recognizing the first lip image sequence through a trained lip recognition model to obtain a lip recognition result; and obtaining a final recognition result according to the speech recognition result and the lip recognition result through a preset speech search tree and a preset lip search tree. The invention also discloses a speech recognition device and a computer readable storage medium. The invention can improve the accuracy of recognition results.

Description

technical field [0001] The invention relates to the technical field of speech recognition, in particular to a speech recognition method, device and computer-readable storage medium. Background technique [0002] Speech recognition technology converts speech signals into corresponding text or commands through machine recognition and understanding, and is the main technology of human-computer interactive communication. At present, speech recognition technology has been applied in various fields, such as communication, automotive electronics, medical treatment, home service, etc., and is playing an increasingly important role. [0003] Although the development of speech recognition technology is very rapid and various speech recognition products emerge in an endless stream, there is still a long way to go before the effect of free human-computer interaction that the field of speech recognition ultimately wants to achieve. For example, the existing speech recognizer is mainly f...
