Embodiment Construction

[0024] In order to solve the problems existing in the prior art, the present invention proposes a method for error detection and error correction of the text after speech recognition, that is, to detect and correct the text after speech recognition based on examples: determine the text in each text sentence An anchor word, extracting the instance of the determined anchor word, and performing error detection and error correction on the text sentence according to the extracted example, because the second grammatical knowledge base and the second semantic knowledge base adopted in the method and the second contextual knowledge base are both created for the domain of the text sentences in the text after the speech recognition, and the anchor words are obtained through the above-mentioned created domain-specific second grammar knowledge base and second semantic knowledge base, That is to say, the obtained anchor words are under the specific field, and the examples are obtained throu...

Abstract

The invention discloses a method for detecting and correcting error on the text after voice recognition, for the purpose of orderly detecting and correcting the sentence errors on the text after voice recognition. The method comprises the steps of respectively creating a second syntactic knowledge base, a second semantic knowledge base and a second contextual knowledge base belonging to the fieldof the sentence on the text after voice recognition, locating heavy duty words on the text according to the second syntactic knowledge base and the second semantic knowledge base, extracting an example of the located heavy duty words based on the second contextual knowledge base, detecting the errors in the sentence based on a first semantic knowledge base and the extracted example and correctingthe wrong words which are detected based on the first semantic knowledge base and the extracted example. The method of the invention can exactly detect and correct the errors on the text after voice recognition to promote the efficiency of voice recognition and realize the free man-machine communication.

Description

technical field [0001] The invention relates to the technical field of natural language processing, in particular to a method for detecting and correcting errors in text after speech recognition. Background technique [0002] Speech recognition technology is a technology that allows machines to convert human language into corresponding text through recognition and understanding. Its ultimate goal is to allow machines to "understand" human language and realize free communication between humans and machines. However, there are often many errors in the text after the existing speech recognition, that is, the speech recognition rate is not very high, which affects the normal communication between humans and machines. Therefore, improving the speech recognition rate has become a key issue in speech recognition technology. It is imperative. [0003] In order to improve the speech recognition rate, it is necessary to detect and correct errors in the text after speech recognition. ...
