Abstract
Mobile phones are now popular in current society for its portability and intelligence, but excluded from life of the hearing-impaired because sounds are unavailable for them. This paper provides a framework of speech based Chinese Sign Language (CSL) Animation System on Smart Phones, which combines speech recognition and sign language animation to make phones convenient for the hearing-impaired. This paper recognizes the Chinese speech into text first, and then proposes a HMMSVM model to judge interrogative expression from the speech and rewrites the plain text as mark-up text according to the rules of Chinese Sign Language Mark-up Language (CSLML) which provides signs for recording expressive context in the text, the corresponding animation is finally synthesized using key-frame technology. The prototype system based on the framework provided in this paper gives plausible Sign Language animation.

A sign language is a language that uses manual communication and body language to convey meaning, instead of acoustically conveyed sound patterns
In the common society, spoken languages, which depend primarily on sound, are the main carrier through the media or long-distance communication, which makes an enormous barrier to the deaf people from obtaining information and getting along with hearing people
Summary
A sign language ( named as signed language or signing) is a language that uses manual communication and body language to convey meaning, instead of acoustically conveyed sound patterns. This can involve simultaneously combining hand shapes, orientation and movement of the hands, arms or body, and facial expressions to fluidly express a speaker's thoughts [1]. According to the data from World Federation of the Deaf, there are around 70 million people with hearing deficiencies all over the world. The amount of sign language interpreters is far from what we really need. Users can get transcripts and corresponding speech simultaneously from the incoming call, which will fulfil deaf people’s expectation of communicating through phones
