Spanish Sign Language Interpreter for Mexican Linguistics

Pérez A.

Journal of Applied Computer Science Methods

2012

Vol. 4 No. 1

75--85

We present here the first visual interface for a Mexican Spanish Sign Language translator on its first development stage: sign-writing recognition. The software was developed for the unique characteristics of Mexican linguistics and was designed in order to use sentences or a sequence of signs in sign-writing system which are decoded by the program and converted into a series of images with movement that correspond to the Mexican sign language system. Using a lexical, syntactic and semantic algorithms plus free software such as APIss from Java, video converter software, data base manager like MySQL, Postgres and SQlite, was possible to read and interpret the rich and complex Mexican language. Our application for visual interface showed to be capable of reading and reconstruct each sentence used for the interpreter and translate it into a high definition video. The average time of video display vs number of sentences to interpret, probed to be in linear relation with an average time of two seconds per sentence. The software has overcome the problem of homonym words frequently used in Spanish language and verb tense relation for each sentence, special symbols such as #, %, $, etc. are still not recognized into the software.
