Research on Input Sign Information Based on Braille Speech Recognition

Abstract

This article is about the software design method of Braille cross platform editing. First, we design Braille Chinese characters dot coding. And then we use Nondeterministic Finite Automaton (NFA) to describe the conversion process between Braille and Chinese words dot coding and use Reverse Order-Splitting-Sets(ROSS) to determine the NFA. Finally, the phonetic sequence of Braille Chinese characters point position coding is used as the phonetic notation of the Braille, in which case the algorithm of speech recognition. The software can enhance the blind human-computer interaction.
