English punctuation mark adding method, system and device based on data enhancement

Abstract

The invention discloses an English punctuation mark adding method, system and device based on data enhancement. The method comprises the steps that text information is acquired and preprocessed to obtain training data, data enhancement processing is conducted on the training data, wherein the data enhancement comprises random deletion, random replacement, random syllable-similar word replacement and random insertion, and enhanced data is obtained; the method further includes integrating the original data before enhancement and the data after enhancement together to serve as a training data set; and performing model training by using the training data set to obtain a prediction model, the prediction model being used for adding English punctuation marks to the input text information. According to the invention, the real data is simulated by performing data enhancement processing on the training data, so that the prediction model obtained by training is more robust, the effect in a speechrecognition system is better, the operand is not increased, and compared with the mode of labeling a large number of real texts with punctuations, the manpower can be saved and the cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of speech recognition, in particular to a method, system and equipment for adding English punctuation marks based on data enhancement. Background technique [0002] In recent years, with the help of machine learning, the rapid development of deep learning, and the accumulation of big data corpus, speech recognition technology has developed by leaps and bounds. Nowadays, with the breakthrough of speech recognition technology research, through speech recognition technology, people's language is converted into text recognition results as instructions and added to related products or as the final result, which can greatly improve the efficiency of human-computer interaction, which has great impact on computer development and society. The importance of life has become increasingly prominent, and the application fields of products developed with speech recognition technology have become more and more extensive, su...
