Abstract

The invention relates to a voice recognition method and device for digital strings. The method comprises: establishing a pronunciation dictionary of digital strings; establishing a multi-category digital string entry based on the pronunciation dictionary; constructing a domain language model according to the multi-category digital string entry; voice recognition. Through the technical solution of the invention, the domain language model established by the number string can be used to quickly recognize the voice number, so as to improve the recognition efficiency and recognition accuracy of the voice containing the number string.

Description

technical field [0001] The invention relates to the technical field of terminals, in particular to a method and device for voice recognition of digital strings. Background technique [0002] At present, when recognizing speech, the speech recognition rate of digit strings is low, especially in some specific scenarios (such as phone number recognition, ID number recognition, bank card number recognition, etc.), the digit recognition rate is far from meeting business needs . [0003] For example: "one", "four", "five", "seven" and other numbers are prone to insertion and deletion errors; ", "Nine Eight" is easily confused as words with similar or identical pronunciations such as "bar". Contents of the invention [0004] The embodiment of the present invention provides a voice recognition method and device for a number string. Described technical scheme is as follows: [0005] According to a first aspect of an embodiment of the present invention, a method for speech recog...
