FastSpeech: Fast, Robust and Controllable Text to Speech

Neural Information Processing Systems

Prominent methods (e.g., Tacotron 2) usually first generate mel-spectrogram from text, and then synthesize speech from the mel-spectrogram using vocoder such as WaveNet. Compared with traditional concatenative and statistical parametric approaches, neural network based end-to-end models suffer from slow inference speed, and the synthesized speech is usually not robust (i.e., some words are skipped or repeated) and lack of con-trollability (voice speed or prosody control).


both R1 and R2 see the significance of these contributions, and R1 is correct: we have gotten a lot of interest in the

Neural Information Processing Systems

We would like to thank the reviewers for their thoughtful comments. However, R2 and R3 had some concerns. Based on initial interest, it seems that many groups will investigate these questions. We think there's value in making these points in the context of these newer techniques. There is also more nuance to our results that R3 is not giving us credit for.

Neural Information Processing Systems

We thank the reviewers for their helpful suggestions, and will do our best to incorporate them into our paper. It is true that LSTMs can be used to solve RL problems with non-Markovian specifications. As we show in our experiments, reward shaping is crucial for learning complex tasks. For example, how does achieving a sub-goal count compared to violating a constraint? These challenges are exactly what our system is designed to solve.






Deep Learning without Weight Transport

Neural Information Processing Systems

In a typical deep-learning network, some signals flow along a forward path through multiple layers of processing units from the input layer to the output, while other signals flow back from the output layer along a feedback path . Forward-path signals perform inference (e.g. they try to infer what objects are
