We are developing a Finnish rule-based TTS system. Our primary concern is to enhance naturalness in the synthesis by observing tendencies in natural language and implementing the findings into the synthesis. We have concentrated on modeling duration, which is essential to the Finnish language due to contrasting phonemic length and the fact that the(More)
Neurofibromatosis 1 (NF1) is a neurocutaneous-skeletal disorder often accompanied with varying degrees of cognitive and motor problems that potentially affect speech and language. While previous studies have shown that NF1 may be associated with a variety of deviations in the patients' speech, they have not investigated the characteristics in phonetic(More)

The goal has been to identify any possible lengthening or shortening effects the domain edge (here, the beginning of an utterance) might have on segmental duration. Duration was observed at phone level. The results indicate that(More)
