|---|---|
| This paper describes the design, development and field evaluation of a Spanish into Spanish Sign Language (LSE: Lengua de Signos Española) translation system. The developed system focuses on helping deaf people when they want to renew their Driver?s License. The system is made up of a speech recognizer (for decoding the spoken utterance into a word sequence), a natural language translator (for converting a word sequence into a sequence of signs belonging to the sign language), and a 3D avatar animation module (for playing back the signs). For the natural language translator, three technological proposals have been implemented and evaluated: an example-based strategy, a rule-based translation method and a statistical translator. For the final version, the implemented language translator combines all the alternatives into a hierarchical structure. This paper includes a detailed description of the field evaluation carried out. This evaluation has been carried out in the Local Traffic Office in Toledo involving real government employees, and deaf people from Madrid and Toledo. The evaluation includes objective measurements from the system and subjective information from questionnaires. The paper reports a detailed analysis of the main problems found and a discussion on how to solve them (some of them specific for Spanish Sign Language). | |
