Abstract

The invention discloses a voice recognition method and device, and relates to the technical field of computers. One specific embodiment of the method comprises the following steps: respectively setting initial values of a Chinese character coefficient and a pinyin coefficient, generating a Chinese character mapping function according to the initial value of the Chinese character coefficient, and generating a pinyin mapping function according to the initial value of the pinyin coefficient; training the Chinese character mapping function and the pinyin mapping function by using a plurality of preset training samples, performing calculating by taking a training result as a parameter of a joint loss function, and generating a target mapping function according to a calculation result; and recognizing to-be-recognized voice according to the target mapping function to obtain a Chinese character recognition result and a pinyin recognition result of the to-be-recognized voice. According to theembodiment, the recognition cost is reduced while the recognition accuracy is ensured.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for recognizing speech. Background technique [0002] At present, using the existing Chinese character recognition method to recognize speech can only recognize the result of Chinese character recognition, and using the existing pinyin recognition method to recognize speech can only recognize the result of pinyin recognition. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] For speech recognition that contains homophones, polyphonic characters, or ambiguous pronunciation, if only the recognition results of Chinese characters or only the recognition results of pinyin are recognized, the recognition accuracy is not high. In order to ensure the recognition accuracy of speech containing homophones, polyphonic characters or ambiguous pronunciation, those skille...
