Abstract:
1. Method for speech signal analysis, modification and synthesis comprising: a. a phase for the location of analysis windows by means of an iterative process for the determination of the phase of the first sinusoidal component of the signal and comparison between the phase value of said component and a predetermined value until finding a position for which the phase difference represents a time shift less than half a speech sample b. a phase for the selection of analysis frames corresponding to an allophone and readjustment of the duration and the fundamental frequency according to a model, such that if the difference between the original duration or the original fundamental frequency and those which are to be imposed exceeds certain thresholds, the duration and the fundamental frequency are adjusted to generate synthesis frames, c. a phase for the generation of synthetic speech from synthesis frames, taking the information of the closest analysis frame as spectral information of the synthesis frame and taking as many synthesis frames as periods that the synthetic signal has.
