Choose Tacotron-2 if…
- Tags unique to Tacotron-2: paper, python, speech-synthesis, tacotron.
- High speech quality demanded, supports Ljspeech and M-AILABS dataset formats
- Leaner open-issue backlog (265).
When NOT to use Tacotron-2
- For non-Ljspeech or M-AILABS datasets, custom preprocessing needed; less flexibility
- If requiring rapid deployment without extensive model tweaking and training
Choose faster-whisper if…
- Requirements: Requires Python 3.9 or greater..
- Tags unique to faster-whisper: deep-learning, inference, openai, quantization.
- Also covers Inference & Serving.
- When you need fast speech-to-text transcription without the need to install FFmpeg separately, as Faster Whisper bundles FFmpeg libraries with PyAV.
When NOT to use faster-whisper
- When your project strictly requires the use of FFmpeg for audio decoding, as Faster Whisper uses PyAV for this purpose.
- When you are working in an environment where Python 3.9 or greater is not available, as this is a requirement for using Faster Whisper.
