Nana-HDR: A Non-attentive Non-autoregressive Hybrid Model for TTS
Note: Text is not shown in the training set, and it is converted into system input (Chinese Pinyin with tone and pause) through the pre-trained front-end model.
Part1: Audio samples synthesized by the Tacotron with GMM-based attention, Fastspeech and our Nana-HDR (using the original LPCNet as the vocoder).
