A speech-processing system receives input data representing text. A prosody prediction component processes the input data to determine prosody embedding data corresponding to prosody of the text. A decoder processes the prosody embedding data and phoneme encoded data derived from the input data to determine audio output data corresponding to the text and the prosody.

Synthetic speech processing related to prosody prediction

A speech-processing system receives first audio data correspond to a first voice and second audio data corresponding to a second voice. The speech-processing system determines vocal characteristics of the second voice and determines output corresponding to the first audio data and the vocal characteristics.

Synthetic speech processing

A speech-processing system receives input data representing text. One or more encoders trained to predict audio properties corresponding to the text process the text to predict those properties. A speech decoder processes phoneme embeddings as well as the predicted properties to create data representing synthesized speech.

Synthetic speech processing by representing text by phonemes exhibiting predicted volume and pitch using neural networks

Devices and techniques are generally described for learned condition text-to-speech synthesis. In some examples, first data representing a selection of a type of prosodic expressivity may be received. In some further examples, a selection of content comprising text data may be received. First audio data may be determined that includes an audio representation of the text data. The first audio data may be generated based at least in part on sampling from a first latent distribution generated using a conditional primary variational autoencoder (VAE). The sampling from the first latent distribution may be conditioned on a first learned distribution associated with the type of prosodic expressivity. In various examples, the first audio data may be sent to a first computing device.

Learned condition text-to-speech synthesis

Techniques for performing text-to-speech are described. An exemplary method includes receiving a request to generate audio from input text; generating audio from the input text by: generating a first number of vectors from phoneme embeddings representing the input text, predicting one or more spectrograms having the first number of frames using multiple scales wherein a coarser scale influences a finer scale, concatenating the first number of vectors and the predicted one or more spectrograms, generating at least one mel spectrogram from the concatenated vectors and the predicted one or more spectrograms, and converting, with a vocoder, the at least one mel spectrogram frames to audio; and outputting the generated audio according to the request.

Multi-scale spectrogram text-to-speech

A speech-processing system receives input data representing text. An input encoder processes the input data to determine first embedding data representing the text. A local attention encoder processes a subset of the first embedding data in accordance with a predicted size to determine second embedding data. An attention encoder processes the second embedding data to determine third embedding data. A decoder processes the third embedding data to determine audio data corresponding to the text.
