Abstract

The invention provides a voice recognition method, and the method comprises the steps: recognizing a projection device with a similar environment at a current moment, and starting two projection devices at the same time during voice recognition, one projection device being used for collecting an audio signal containing a user audio, and the other projection device being used for collecting a voice signal containing the user audio; the other delivery device is used for collecting mixed audio of audio and noise in the environment, performing audio separation on an audio signal containing user audio through the mixed audio to obtain the user audio which is less influenced by the environment, performing voice recognition on the user audio to obtain a voice instruction of the user, and sending the voice instruction to the other delivery device. Through the method, the accuracy of the voice recognition result can be improved, and the accuracy of obtaining the voice instruction can be improved.

Description

technical field [0001] The present application relates to the technical field of speech recognition, and in particular, to a speech recognition method. Background technique [0002] With the development of science and technology, speech recognition technology is applied to more and more fields in order to assist users in using devices. [0003] For the medical testing equipment put on the market, in order to facilitate the self-service use of patients, a voice recognition function is installed on the medical testing equipment, and the patient can enable the corresponding function through voice commands (that is: start the corresponding function on the medical testing equipment), For example: the patient's voice can be "I want to check blood pressure", then the medical testing equipment recognizes the text information through the speech recognition function, and then determines the function that the patient wants to enable through the semantics of the text information, and th...
