In this article we present the main linguistic and phonetic features of Galician which need to be considered in the development of speech technology applications for this language. We also describe the solutions adopted in our text-to-speech system, also useful for speech recognition and speech-to-speech translation. On the phonetic plane in particular, the(More)
This paper will present the morphosintactic tagger and the corpus of contemporary written Galician which are being employed in the development of the Galician version of our tex-to-speech synthesizer. Their quality and accuracy make them useful for speech technology applications and turn them into possible references for further investigation and research(More)
Traditionally, corpus-based text-to-speech systems generate the speech signal as the result of a two-staged process. First, the target prosody is determined and, after that, a set of speech units that minimize a cost function is selected. Once the target prosody is selected, no alternative prosodic information is generally considered, even when appropriated(More)
This paper describes the result of a joint R&D project between Microsoft Portugal and the Signal Theory Group of the University of Vigo (Spain), where a set of language resources was developed with application to Text–to–Speech synthesis. First, a large Corpus of 10000 Galician sentences was designed and recorded by a professional female speaker. Second, a(More)
This paper will present the design of a Galician syntactic corpus with application to intonation modeling. Our paper paid attention to phonetics and syntactic phenomena to achieve a comparison beetwen its appearances. A corpus of around 3000 sentences was designed with variation in the syntactic structure and the number of accent groups, and recorded by a(More)
This paper describes the first TTS evaluation campaign designed for Spanish. Seven research institutions took part in the evaluation campaign and developed a voice from a common speech database provided by the organisation. Each participating team had a period of seven weeks to generate a voice. Next, a set of sentences were released and each team had to(More)
