FastSpeech 1 is a neural network-based text-to-speech (TTS) synthesis model designed to generate speech in a fast, efficient, and high-quality manner. It utilizes a non-autoregressive architecture to significantly improve speech generation speed compared to traditional autoregressive models, enabling real-time speech synthesis with improved robustness.
Key Features
- Non-autoregressive architecture for faster inference
- Parallel token generation leading to real-time speech synthesis
- Enhanced stability and robustness in speech output
- Utilizes duration prediction to control speech timing
- Improved synthesis latency without sacrificing quality
Pros
- Significantly faster inference speed suitable for real-time applications
- High-quality natural-sounding speech synthesis
- Reduced computational complexity compared to autoregressive models
- More stable and robust performance across diverse inputs
- Effective use of duration prediction enhances temporal control
Cons
- Requires accurate duration prediction modules for optimal quality
- Potentially less controllable than autoregressive models in some scenarios
- Still relies on neural vocoders or additional components for final waveform generation
- May require substantial training data and computational resources
