Because pitch is an explicit input signal to the decoder, users can edit it to change delivery. The paper reports high mel-spectrogram synthesis throughput under its evaluation setup; this does not measure end-to-end waveform generation latency.
Jin Dive
FastPitch (Łańcucki, 2020) is a fully parallel TTS model based on FastSpeech. It predicts token durations and fundamental-frequency contours, then conditions a mel-spectrogram decoder on them. During training, the pitch target is averaged over the aligned acoustic frames for each input token. Editing the predicted contour at inference can change intonation without retraining. The paper reports more than 900× real-time factor for mel-spectrogram synthesis of a typical utterance; waveform generation by a vocoder is a separate stage.

Ojo iwaju ti FastPitch ipolowo-Controllable TTS
Explicit pitch and duration controls remain useful for interpretable TTS pipelines. Later systems can add energy, emotion, and speaker controls or learn more flexible representations. Runtime comparisons should distinguish mel-spectrogram generation from the complete text-to-waveform pipeline.

Kini FastPitch Pitch-Controllable TTS?
FastPitch is a fully parallel text-to-speech model based on FastSpeech that conditions mel-spectrogram generation on predicted fundamental-frequency contours. Because pitch is an explicit input signal to the decoder, users can edit it to change delivery. The paper reports high mel-spectrogram synthesis throughput under its evaluation setup; this does not measure end-to-end waveform generation latency.

How can a user change the intonation contour in FastPitch output without retraining?
Pitch is an explicit contour that can be edited to alter intonation; the perceptual effect depends on context and does not guarantee a particular emotion or emphasis.

What synthesis throughput did the FastPitch paper report for a typical utterance?
The paper reports over 900× real-time factor for mel-spectrogram synthesis; this does not include every downstream vocoder or serving step.
