Problems solved by technology

[0003] However, the higher accuracy of speech recognition depends on the speaker being able to speak clearly. For people who cannot speak clearly, such as patients with sequelae of cerebral apoplexy, the accuracy of speech recognition will be lower due to their ambiguous pronunciation. High, making them unable to use speech recognition technology normally, which greatly affects the user experience and limits the application of speech recognition technology

Abstract

The invention discloses a speech recognition method, electronic equipment and a storage device. The method comprises the following steps: acquiring to-be-recognized data when a user speaks, wherein the to-be-recognized data comprises audio data and video data of the mouth of the user; extracting a first feature representation by using the video data, and extracting a second feature representation by using the audio data; performing the following identification steps on the to-be-recognized data for several times: acquiring a fused context representation of the video data and the audio data by using the first feature representation, the second feature representation and the predicted text identified last time, and performing prediction by using the fused context representation to obtain the predicted text identified this time; and taking a combination of the predicted characters identified for several times as a final identification text of the to-be-recognized data. According to the scheme, the accuracy of speech recognition can be improved.

Description

technical field [0001] The present application relates to the technical field of voice recognition, in particular to a voice recognition method, electronic equipment and a storage device. Background technique [0002] Voice recognition is to recognize the input voice data to obtain the recognized text content corresponding to the voice. The application of speech recognition technology has greatly promoted people's input efficiency, making it more convenient and faster for people to input information. [0003] However, the higher accuracy of speech recognition depends on the speaker being able to speak clearly. For people who cannot speak clearly, such as patients with sequelae of cerebral apoplexy, the accuracy of speech recognition will be lower due to their ambiguous pronunciation. High, making them unable to use speech recognition technology normally, greatly affecting the user experience, and also limiting the application of speech recognition technology. In view of th...
