CONTROLLING EXPRESSIVITY IN END-TO-END SPEECH SYNTHESIS SYSTEMS
A system (900) includes a context encoder (610), a text-prediction network (520), and a text-to-speech (TTS) model (650). The context encoder is configured to receive one or more context features (602) associated with current input text (502) and process the one or more context features to generate...

| description | A system (900) includes a context encoder (610), a text-prediction network (520), and a text-to-speech (TTS) model (650). The context encoder is configured to receive one or more context features (602) associated with current input text (502) and process the one or more context features to generate a context embedding (612) associated with the current input text. The text-prediction network is configured to process the current input text and the context embedding to predict, as output, a style embedding (650) for the current input text. The style embedding specifies a specific prosody and/or style for synthesizing the current input text into expressive speech (680). The TTS model is configured to process the current input text and the style embedding to generate an output audio signal (670) of expressive speech of the current input text. The output audio signal has the specific prosody and/or style specified by the style embedding. |
