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 tensorflow-speech-recognition - Last GitHub push was 906 days ago (dormant maintenance, Jan 17, 2024). Validate activity before betting a new project on tensorflow-speech-recognition. - Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge. ## Common questions ### What is the difference between TTS and tensorflow-speech-recognition? TTS: 🐸💬 - a deep learning toolkit for Text-to-Speech, battle-tested in research and production. tensorflow-speech-recognition: 🎙Speech recognition using the tensorflow deep learning framework, sequence-to-sequence neural networks.
