Embodiment Construction

[0036] Below in conjunction with specific embodiments, the present invention will be further illustrated, and it should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. The modifications all fall within the scope defined by the appended claims of this application.

[0037] like figure 1 As shown, the Chinese text verification system based on Chinese fuzzy pronunciation and speech recognition consists of a speech acquisition and processing module, a speech recognition module and a text verification and sharing module.

[0038] The speech acquisition and processing module includes an audio acquisition unit, an audio coding processing unit and a speech noise reduction unit. The audio collection unit collects the user's recording content by calling the microphone of the mobile phone. The higher the audio sampling frequency, the smaller the interval between sampling points and the larger the...

Abstract

The invention discloses a Chinese text verification system and method based on Chinese vague pronunciation and voice recognition. The system comprises a voice collecting and processing module, a voice recognition module and a text verifying and sharing module, wherein the voice collecting and processing module is used for collecting an audio and compressing and denoising the audio, the voice recognition module is used for recognizing voices into a text, and the text verifying and sharing module is used for achieving text verification and meanwhile supports text editing and sharing. The method comprises the steps that Chinese error judgment rules based on parts of speech are defined; word segmentation is carried out on the Chinese text obtained after voice recognition; the segmented words are scanned according to the Chinese error judgment rules to find out wrong Chinese words; a vogue pronunciation table is defined based on Chinese vogue pronunciation rules; all vogue pinyin of the wrong words is found out through a Cartesian product mode; a dictionary table is inquired to obtain a candidate word set of all the vogue pinyin; a candidate error correction set is selected out of words of the candidate set of all the vogue pinyin according to a word frequency rank. By means of the Chinese text verification system and method based on Chinese vague pronunciation and voice recognition, Chinese errors, caused by Chinese vogue pronunciation, in voice recognition are eliminated, and the error correction accuracy rate of a verification algorithm is effectively increased.

Description

technical field [0001] The invention relates to a Chinese text verification system and method based on Chinese fuzzy pronunciation and speech recognition, and belongs to the technical field of intelligent speech recognition. Background technique [0002] As an important research field in the field of intelligent recognition, speech recognition technology has a development history of more than 60 years. Speech recognition is the process of recognizing sound into text, and Chinese speech recognition is to convert speech into Chinese text according to the speaker's pronunciation. However, due to individual differences in pronunciation, irregular Chinese pinyin pronunciation will greatly reduce the accuracy of speech recognition. If we can intelligently analyze the Chinese text after speech recognition, find and correct the wrong words, it will greatly improve speech recognition. degree of precision. [0003] In recent years, solutions to text after speech recognition have eme...
