Problems solved by technology

The current existing methods generally adjust the Chinese word segmentation results based on the Braille word segmentation rules to obtain the Braille after word segmentation. However, because the Braille word segmentation rules are generally related to semantics and have a certain degree of subjectivity, the accuracy of word segmentation when automatically completed by a computer Low, after using these methods for conversion, a lot of manual correction work is required, resulting in low efficiency, and also makes the acquisition of Braille text resources take a long time and cost high

Embodiment Construction

[0052] In order to make the purpose, technical solution and advantages of the present invention clearer, the method for reading Chinese characters for the blind of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used To explain the present invention, not to limit the present invention.

[0053] The main flow of the method for the blind to read Chinese characters of the present invention is as attached figure 1 As shown, the input is a Chinese sentence, that is, a Chinese character string, and the output is the corresponding Braille, which is displayed on a dot display for the blind.

[0054] Step 1. Chinese word segmentation. That is, the Chinese word segmentation system is used to divide the input Chinese character string into a sequence of Chinese words, and the Chinese character string after word segmentation is obtain...

Abstract

The invention provides a method and a system for blind people to read Chinese characters, and relates to the technical field of natural language processing and the technical field of disabled-oriented human-computer interaction. The method comprises the following steps: obtaining a Chinese language text, carrying out a word segmentation operation on the Chinese language text to generate a Chinese character string, converting each word in the Chinese character string into corresponding Pinyin by referring to part-of-speech tagging obtained by word segmentation through a pronouncing dictionary, a polyphone dictionary and word frequency information, and connecting the Pinyin into a Pinyin string; looking up a Pinyin and blind character contrast dictionary, converting the Pinyin string into a blind character string, carrying out braille word segmentation on the blind character string through a word segmentation model to generate initial braille segmentation words, fusing the Chinese character string with the initial braille segmentation words to generate new braille segmentation words, and regulating the new braille segmentation words according to a braille segmentation word ligature rule; and carrying out braille tone marking on the new braille segmentation words regulated according to the braille segmentation word ligature rule to generate final braille segmentation words, and displaying the final braille segmentation words.

Description

technical field [0001] The invention relates to the technical field of natural language processing and the technical field of human-computer interaction for the disabled, in particular to a method and system for blind people to read Chinese characters. Background technique [0002] In today's information society, the level of informatization is constantly improving, information technology has been widely used in people's work, study and life, and the Internet has become an important part of people's daily life. Provides a wealth of information resources. In China, various digital and network text resources are mostly stored in the form of Chinese text, and these resources are difficult to be used by the 12 million blind people in our country. This prevents blind people from enjoying massive information resources like normal people, widens the information gap between blind people and normal people, and further restricts blind people's ability to survive and develop in an inf...
