Avaliação do tratamento de aspectos gramaticais de tradutores automáticos do português brasileiro para libras

Abstract

The development of Assistive Technologies (TA), as resources to enable access to information, provides new forms of interaction, socialization and accessibility for deaf people. In this way, the use of automatic translators between oral languages and sign languages has been widely disseminated. Considering the complexity of the process of translation between oral and sign languages, its automatic realization may not include all the grammatical aspects of Libras, such as the treatment of homonymous words, denial adverbs and directional verbs. The inadequate handling of these aspects may compromise the user's understanding of the translation presented by the translators and consequently interfere with the communication making the deaf user experience with these tools inadequate. Thus, this study analyzes the automatic translation of the Portuguese Language (LP) into the Libras by three automatic ranslators, ProDeaf, HandTalk and VLibras, based on evaluations of 16 interpreters in Libras to the treatment of sentences that have these grammatical aspects. Signi cant weaknesses were observed in the evaluation of the adequacy treatment of homonymous words, adverbs of negation and directional verbs in the translations performed by the applications, which indicates the need to improve these tools in the treatment of these grammatical aspects.
