Validate activity before betting a new project on metavoice-src. - 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 metavoice-src and faster-whisper? metavoice-src: Foundational model for human-like, expressive TTS. faster-whisper: Faster Whisper transcription with CTranslate2.
