Patent

CA 2213779

Portions of recorded speech waveform (e.g. corresponding to phonemes) are combined to synthesise words. In order to provide a smoother delivery, each voiced portion of a waveform portion has its amplitude adjusted to a predetermined reference level. The scaling factor used is varied gradually over a transition region between such portions and between voiced and unvoiced portions.

Des parties de forme d'onde de parole enregistrée (correspondant par ex. à des phonèmes) sont combinées pour synthétiser des mots. Pour que le résultat ne soit pas heurté, chaque partie de parole d'une partie de forme d'onde possède une amplitude ajustée à une niveau de référence prédéterminé. Le facteur d'échelle utilisé est modifié de manière graduelle sur une région de transition entre lesdites parties et entre des parties comportant de la parole ou exempte de parole.
