Parakeet is amazing - 3000x real-time on an A100 and 5x real-time even on a laptop CPU, while being more accurate than whisper-large-v3 (https://huggingface.co/spaces/hf-audio/open_asr_leaderboard). NeMo is a little awkward though; I'm amazed it runs locally on Mac (for MacWhisper).
Yeah, Parakeet runs great locally on my M1 laptop (through MacWhisper). Transcription speed of recordings feel at least 10x faster than Whisper, and the accuracy is better as well. Push to talk for dictation is pretty seamless since the model is so fast. I've observed no downside to Parakeet if you're speaking English.
Parakeet v3 supports many more languages. Works great with MacWhisper.
