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. ## When NOT to use faster-whisper - * When needing to employ FFmpeg directly for audio processing as it does not require FFmpeg installation and relies instead on PyAV. - * In environments where additional dependencies from PyAV may introduce complexity or issues. ## Common questions ### What is the difference between TTS and faster-whisper?
