FastSpeech 2 is a text-to-speech (TTS) synthesis model designed to generate natural and high-quality speech efficiently. Building upon its predecessor FastSpeech, it introduces improvements such as better prosody modeling, more accurate duration prediction, and enhanced robustness, enabling more expressive and realistic speech output with faster inference times.
Key Features
- Non-autoregressive architecture for high-speed inference
- Improved prosody control and expressive speech synthesis
- Enhanced duration, pitch, and energy prediction modules
- Robust to noisy or imperfect input data
- High-quality, natural-sounding synthesized speech
Pros
- Significantly faster inference compared to autoregressive models
- Produces natural and intelligible speech with good expressiveness
- Flexible control over speech prosody attributes
- Less prone to errors caused by input noise or errors
- Suitable for deployment in real-time applications
Cons
- Requires substantial computational resources for training
- May still face challenges in perfectly capturing extremely nuanced prosody
- Complexity of implementation can be higher compared to simpler models
- Dependent on high-quality training data for optimal results
