Tone-character conversion method

Abstract

The invention discloses a sound-character conversion method, belonging to the field of Chinese information processing technology. The method comprises the following steps of: syncopating an input pinyin string, converting syllables into Chinese characters by utilizing a word tree layer, and simultaneously calling an ambiguity processing module to determine the ambiguity for the syncopated syllables; if the ambiguity exits, syncopating is carried out again, and the ambiguity comprises an I type ambiguity and / or an II type ambiguity; and by utilizing a trained language module, the method sorts the probability scores of alternative words of the syllables and obtains word hybrid grids and text strings in a universal decoding layer according to the scores. Compared with the prior art, the method covers all possible syncopations, solves the problem of most syncopation ambiguities, ensures definite efficiency, can not generate combined explosion based on code element syncopation, saves memory storage space, reduces the restrictions on the storage space, and can be used for Chinese information processing, comprising Chinese character input, voice input and the like.

Description

A method of phonetic conversion technical field The present invention relates to Chinese character input, in particular, the present invention relates to a method for converting pinyin strings into Chinese character strings, which is mainly used in the post-processing stage of internal decoding and speech recognition of the Chinese pinyin input method. It belongs to the technical field of Chinese information processing. Background technique Phonetic character conversion refers to the conversion of Chinese syllable strings (pinyin strings) into Chinese character strings automatically by a computer. Phonetic-to-character conversion technology is an important foundation in Chinese information processing and has a wide range of applications. For example, the Chinese Pinyin keyboard input method and speech recognition system will be used. Chinese character input is the basis of Chinese information processing, and phonetic-to-character conversion is the core algorithm of Chine...

Problems solved by technology

4. The multiple ambiguities mentioned above are adjacent to each other, resulting in more complex combination ambiguities

Its disadvantage is that it requires a considerable amount of training text to determine the parameters of the model
