Problems solved by technology
The invention discloses a voice recognition result error correction method which includes the steps: preprocessing voice recognition results; finding out error-prone words and sentences in the voice recognition results or semantically parsing important words and characters to be corrected for a text; performing phonetic notation on the words and characters to be corrected in a complete spelling mode and a phonetic initial spelling mode to obtain unpitched pinyin corresponding to the recognition results of voice to be corrected; determining an optimal candidate text and a sub-optimal candidatetext by the aid of an editing distance algorithm according to the complete spelling mode; determining an optimal candidate text and a sub-optimal candidate text by the aid of the editing distance algorithm according to phonetic initials; combining all the optimal candidate texts and all the sub-optimal candidate texts, and only reserving one repeated candidate item; replacing a text to be corrected by a prospective candidate text, calculating the probability of replaced statements by an n-grama language model and selecting the statement with the highest probability as a final recognition result of the voice to be corrected.
