Claim 9:
10. The method of claim 8, wherein training the prosody model further comprises, for each reference audio signal:
sampling, from the corresponding reference audio signal, a sequence of fixed-length reference frames providing a duration, pitch contour, and/or energy contour that represents the corresponding prosody of the reference audio signal;
decoding, using the transcript of the corresponding reference audio signal, the corresponding fixed-length utterance embedding into a sequence of fixed-length predicted frames representing a prosodic representation of the transcript;
generating gradients/losses between the sequence of fixed-length predicted frames decoded from the corresponding fixed-length utterance embedding and the sequence of fixed-length reference frames sampled; and
back-propagating the gradients/losses through the prosody model.
