Validate activity before betting a new project on TensorFlowASR. - 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 faster-whisper and TensorFlowASR? faster-whisper: Faster Whisper transcription with CTranslate2. TensorFlowASR: :zap: TensorFlowASR: Almost State-of-the-art Automatic Speech Recognition in Tensorflow 2. Supported languages that can use characters or subwords. See the comparison table for live GitHub stats and shared categories. ### When should I choose faster-whisper over TensorFlowASR?
