A process and a device for the musical and vocal dynamic sound synthesis of formants associated with a fundamental sound. To produce a formant, a wave form is generated with is the sum of several sound components of the form <IMAGE> wherein omega 0 denotes the angular frequency of the fundamental sound, omega s denotes a shift of angular frequency of the formant with respect to the fundamental sound, omega c denotes the central angular frequency of this formant, and delta denotes the bandwidth of the latter. The amplitude of each component is of the form: <IMAGE> The frequency or angular frequency parameters are modulated temporally in order to carry out the dynamic sound synthesis, the phase relations between formants thus being preserved.
