Parakeet
Parakeet is a family of open-source speech recognition models from NVIDIA, built on a transducer architecture that emits words as audio arrives. It is the streaming counterpart to batch models like Whisper and a common engine inside live dictation tools.
Parakeet models are trained for the same job as Whisper but with a different shape: instead of reading a whole chunk before writing, a transducer produces tokens continuously, so text can appear while you are still speaking. On Apple silicon the smaller Parakeet variants run in real time with room to spare, which makes them a natural fit for dictation where the words should land at key-up.
The trade is coverage. Parakeet models are trained on a smaller set of languages than Whisper, so tools that use one for streaming pair it with a batch model for everything else.
Transducer versus encoder-decoder
An encoder-decoder model like Whisper is a reader and a writer: the encoder digests a window of audio, then the decoder writes the transcript. A transducer joins the two so that every new slice of audio can produce a new token without waiting for the window to close. That is what streaming needs, and it is also why transducers tend to be more stable on long audio: they never get to "reconsider" a whole passage and repeat it.
Where it fits in a dictation tool
Parakeet is the engine you want running while the key is held. It gives the live transcript in the notch or the pill, confirms you were heard, and leaves almost nothing to do at key-up. The final text quality still depends on the formatting stage that follows, and on a dictionary for names, exactly as with any ASR model.

Flit runs its speech and formatting models on your Mac. Which models are in the stack changes with releases; that they never leave the machine does not.

Fair questions.
What is Parakeet in speech recognition?
An open-source family of ASR models from NVIDIA built to stream: words come out as audio goes in. It is often paired with Whisper, which covers more languages but works in batch.
Is Parakeet better than Whisper?
For live dictation in a supported language, it feels better because text appears as you speak. For language coverage and for transcribing files, Whisper is broader. Good tools use each for what it is best at.
