Automatic translation of Chinese text to Chinese Braille is important for blind people in China to
acquire information using computers or smart phones. In this paper, a novel scheme of Chinese-Braille translation
is proposed. Under the scheme, a Braille word segmentation model based on statistical machine learning is trained
on a Braille corpus, and Braille word segmentation is carried out using the statistical model directly without the
stage of Chinese word segmentation. This method avoids establishing rules concerning syntactic and semantic
information and uses statistical model to learn the rules stealthily and automatically. To further improve the
performance, an algorithm of fusing the results of Chinese word segmentation and Braille word segmentation
is also proposed. Our results show that the proposed method achieves accuracy of 92.81% for Braille word
segmentation and considerably outperforms current approaches using the segmentation-merging scheme.
