Abstract
(EN)
A voice synthesizer (10) includes a memory for storing basis functions, each basis function including a set of data representing a speech waveform segment recorded at a basic storage rate and each basis function defining a waveform segment including plural formants F1 and F2. In the synthesizer, each basis function is represented by a data point plotted on a single line on a chart having first and second formant log-log axes. A speech waveform segment approximately representing any desired point located off the single line on the chart is produced by selecting and reading out of the memory one of the basis functions at a rate different from the basic storage rate.

Un synthetiseur de voix (10) comprend une memoire d"emmagasinage de fonctions de base, chaque fonction de base comprend un groupe de donnees representant un segment d"onde de conversation enregistre a une vitesse d"emmagasinage de base, et chaque fonction de base definissant un segment d"onde comprenant une pluralite de "formants" F1 et F2. Dans le synthetiseur, chaque fonction de base est representee par un point-donnee marque sur une seule ligne d"un graphique ayant un premier et un second axes log-log "formants". Un segment d"onde de conversation representant approximativement un point quelconque voulu situe en dehors de la ligne du graphique est reproduit en selectionnant et en lisant dans la memoire une des fonctions de base a une vitesse differente de la vitesse d"emmagasinage de base.
