The embodiment of the invention provides a voice recognition model acquisition method and device. The method comprises the steps: determining a rhythm word according to a sample word, and obtaining atarget preset word; labeling position information for the phoneme corresponding to the target preset word according to the position of each character in the target preset word to obtain a target phoneme, the position information used for representing the position of the phoneme in target preset word pronunciation; and performing training to obtain a target speech recognition model according to thetarget phoneme and the target preset word. According to the embodiment of the invention, the position information is labeled based on the rhythm words, so that the position information can truly reflect the rhythm of actual pronunciation; therefore, the speech recognition model is trained based on the target preset words and the labeled target phonemes, so that the speech recognition model can bemore accurate, and the recognition rate of speech recognition can be improved.
Description
technical field [0001] The invention relates to the field of speech recognition, in particular to a method and device for acquiring a speech recognition model. Background technique [0002] Automatic Speech Recognition (ASR) is a technology that studies how to convert human speech recognition into text. It is widely used in voice dialing, voice navigation, indoor device control, voice document retrieval, simple dictation data entry, etc. in service. [0003] In order to implement speech recognition, it is often necessary to obtain a speech recognition model. Therefore, there is an urgent need for a method for acquiring a speech recognition model. Contents of the invention [0004] Embodiments of the present invention provide a method and device for acquiring a speech recognition model to solve the problem of low speech recognition accuracy in the prior art. [0005] In order to solve the above problems, the embodiment of the present invention is implemented as follows: ...
