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.
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.
Raising or lowering a predicted pitch contour to change the intonation of a generated utterance
Comparing parallel spectrogram synthesis with autoregressive speech-generation pipelines
Inspecting per-phoneme pitch values alongside predicted token durations
Using pitch-conditioned synthesis in controlled TTS experiments
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.

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.
FastPitch menambah peramal nada yang mengeluarkan satu nilai frekuensi asas bagi setiap token input, digunakan untuk mengkondisikan penyahkod spektrogram.
FastPitch bukan autoregresif: ia mengira semua bingkai output secara serentak dan bukannya satu langkah pada satu masa, menjadikannya jauh lebih pantas daripada model autoregresif.
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.
FastPitch membuat purata kekerapan asas kebenaran asas merentas setiap bingkai token, jadi model mempelajari satu nilai nada intuitif bagi setiap simbol.
The paper reports over 900× real-time factor for mel-spectrogram synthesis; this does not include every downstream vocoder or serving step.
