Claim 15:
16. The speech synthesis device according to claim 11, wherein the method further comprising: training the speech synthesis model,
wherein a training method comprises:
dividing a speech sample corresponding to each of training texts into different frames according to a preset frequency, extracting an acoustic characteristic parameter for each frame, and generating a first acoustic characteristic parameter sample corresponding to each of the training texts respectively;
training the acoustic parameter prediction model by using the first acoustic characteristic parameter sample corresponding to each of the training texts and each of the training texts;
converting each of the training texts into a second acoustic characteristic parameter sample respectively by using a trained acoustic parameter prediction model;
converting a speech sample corresponding to each of the training texts into a vocoder characteristic parameter sample respectively according to a synthesis frequency of the vocoder; and
training a vocoder parameter conversion model by using the second acoustic characteristic parameter sample corresponding to each of the training texts and the vocoder characteristic parameter sample.
