Abstract

dressed through improvements to its transcription, clustering, and segmentation capabilities. The LP synthesis scheme was replaced by a TD-PSOLA scheme which synthesised speech by concatenating waveform segments selected to represent each clustered state. The final system produced speech which, though in a monotone, was natural sounding, remarkably fluent, and highly intelligible. The segmental intelligibility was measured using the Modified Rhyme Test, and a 5.0% error rate obtained. The speech produced by the system mimicked the voice of the speaker used to record the training database. The system could be retrained on a new voice in less than 48 hours, and has been successfully trained on four voices.

To him I am deeply grateful, both for letting me join the CUED Speec
