Las tecnologías del habla en las lenguas románicas ibéricas

Abstract This paper reviews the development of speech technologies for Iberian Romance languages (Catalan, Galician, Spanish and Portuguese) with a special emphasis on the phonetic knowledge involved in the three core areas in the field: text-to-speech synthesis, automatic speech recognition and spoken language systems. Several important technological advances have taken place during the last decades and there is a substantial base of active researchers in the areas of engineering and computer science. However, the trend towards the use of automatic learning techniques and corpus-based models has seriously reduced the role of linguistics, favoring a reduction in time in the development of applications over basic research into the nature of the speech code.
