Claim 8:
9. The speech synthesis method according to claim 4, wherein,
the acoustic parameter prediction model comprises: an encoder, a decoder, and an attention model, and the inputting the phoneme sequence into the acoustic parameter prediction model of the speech synthesis model, to convert the phoneme sequence into the acoustic characteristic parameter comprises:
inputting the phoneme sequence to the encoder, and obtaining a characteristic representation corresponding to each element in the phoneme sequence output by the encoder;
inputting a characteristic representation corresponding to each element, a hidden state of the decoder output at a current moment by a first recurrent layer in the decoder, and a cumulative information of an attention weight corresponding to each element at a previous moment into the attention model, to obtain a context vector;
inputting a hidden state of the decoder output at the current moment by a first recurrent layer of the decoder and the context vector into a second recurrent layer of the decoder, to obtain a hidden state of the decoder output at the current moment by the second recurrent layer of the decoder; and
predicting the acoustic characteristic parameter according to a hidden state of the decoder at each moment output by the decoder.
