Parakeet TDT 1.1B
Fast and accurate English speech recognition with built-in word timestamps.
About
Parakeet TDT 1.1B is a 1.1 billion parameter English automatic speech recognition model from NVIDIA's NeMo Parakeet family. It pairs a 42-layer FastConformer encoder with a Token-and-Duration Transducer decoder, giving strong accuracy on diverse accents and noisy audio with efficient inference.
The model outputs lowercase English text and produces word-level timestamps natively from the TDT decoder, which makes it handy for subtitles, voice analytics, and transcription pipelines. Weights are released under CC-BY-4.0, so it can be used commercially.
