Problems solved by technology

[0002] In the prior art, when generating a dictionary containing word fragments based on an English dictionary, the dictionary is usually generated based on the adjacent sequence with the highest co-occurrence frequency of English words, but the word fragments generated in this way cannot be guaranteed to be consistent with English words. Corresponding pronunciation, which leads to the problem of large amount of calculation, high delay, and inability to be uploaded to the screen in real time when recognizing English words based on dictionaries

Abstract

The invention discloses a dictionary generation and speech recognition method, and relates to the technical field of natural language processing and speech processing. The dictionary generation method comprises the following steps: acquiring an English dictionary; segmenting each English word according to the pronunciation of each English word in the English dictionary so that the number of word segments obtained by segmenting each English word is equal to the number of pronunciation segments of each English word; and generating a dictionary according to the word segments of the English words. The speech recognition method comprises the following steps: acquiring an input audio; and searching a target word segment corresponding to the pronunciation segment of the input audio in a dictionary, and generating a recognition result of the input audio according to the searched target word segment. The word segments in the generated dictionary are in one-to-one correspondence with the pronunciation segments of the English words so that the accuracy and efficiency of speech recognition can be improved.
