FastSpeech 2
FastSpeech 2What is FastSpeech 2?
FastSpeech 2 is a state-of-the-art text-to-speech (TTS) model developed to improve both the speed and quality of speech synthesis. Building upon the original FastSpeech architecture, FastSpeech 2 introduces variance predictors for pitch, energy, and duration, resulting in more natural and expressive speech.
Its non-autoregressive architecture allows for parallel processing, making it significantly faster than traditional models like Tacotron 2 while maintaining or exceeding output quality.
