Choose TTS if…

  • TTS is primarily Python; FluidAudio is Swift.
  • License: TTS is MPL-2.0, FluidAudio is Apache-2.0.
  • Tags unique to TTS: deep-learning, glow-tts, hifigan, melgan.
  • Also covers Model Training.
  • TTS ships Docker support for self-hosted deployment.

When NOT to use TTS

  • Last GitHub push was 694 days ago (dormant maintenance, Aug 16, 2024). Validate activity before betting a new project on TTS.
  • Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.
  • Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.

Choose FluidAudio if…

  • FluidAudio is primarily Swift; TTS is Python.
  • License: FluidAudio is Apache-2.0, TTS is MPL-2.0.
  • Tags unique to FluidAudio: ane, asr, audio, automatic-speech-recognition.
  • Also covers Vector Databases.

When NOT to use FluidAudio

  • Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.
  • Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.
