Choose Tacotron-2 if…
- Tags unique to Tacotron-2: wavenet, tacotron, paper, speech-synthesis.
- Also covers Evaluation & Observability.
- Leaner open-issue backlog (265).
When NOT to use Tacotron-2
- Last GitHub push was 1101 days ago (dormant maintenance, Jul 6, 2023). Validate activity before betting a new project on Tacotron-2.
- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.
- Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers.
Choose GPT-SoVITS if…
- Tags unique to GPT-SoVITS: voice-cloning, voice-clone, voice-cloneai, tts.
- Also covers Computer Vision.
- GPT-SoVITS ships Docker support for self-hosted deployment.
