1st Joint SIG-IL/Microsoft Workshop on Speech and Language Technologies for Iberian Languages
Porto Salvo, Portugal
This paper presents some preliminary issues and proposed solutions in the development of an accent-independent pronunciation lexicon for Portuguese, known as the Portuguese Unisyn Lexicon (LUPo). LUPo's objectives are presented within the context of the Portal da Língua Portuguesa knowledge base. Key considerations are addressed for encoding morphological boundaries, treating orthographic forms, and handling loan words. Here, it is argued that the knowledge-driven paradigm exemplified in the original English Unisyn Lexicon, along with the Portal da Língua Portuguesa's relational structure and rich lexicographic content present a good foundation for establishing a tightly integrated and well informed system.
