Abstract

In a synthesiser which, for each sampling period, reconstitutes a language element by means of three sinusoidal components obtained with the help of variable-frequency generators and variable-attenuators, those components are simultaneously subject to predetermined rephasing operations carried out at an auxiliary frequency identified with the pitch frequency (or frequency of vibration of the voice) at the time of emission of vowels or voiced consonants. This auxiliary frequency is delivered by a further variable-frequency generator. In addition, the signal representing the sum of these components is amplitude-modulated by a modulating signal at the auxiliary frequency.
