Abstract:

Applying the theory of CI-NLU (comprehensive information based natural language understanding, which protests that natural language could be understood through analyzing comprehensive information, the entirety of syntactic, semantic and pragmatic information.) into the research of reliable Speech Recognition, a new method of adding a text post-processing function of CI-NLU is put forward. The syntactic information of words (location and Speech Recognition stability), semantic information (meaning of sentence) and pragmatic information (harmony of word and its environment) are analyzed to check the sentence reliability of Speech Recognition result. Testing results have shown that the accuracy could be improved to a good extent.

Key words: comprehensive information, natural language processing, asr post-processing, reliability
