Parakeet-tdt-0.6b-v2: A 600M-parameter ASR model for accurate English transcription with punctuation, capitalization & timestamp prediction. Handles 24-min audio efficiently.

Accurate Speech-to-Text for Demanding Workflows
Parakeet-tdt-0.6b-v2 is a state-of-the-art 600-million-parameter automatic speech recognition (ASR) model engineered for professional-grade English transcription. Built on NVIDIA’s FastConformer architecture and enhanced with the Token-and-Duration Transducer (TDT) decoder, it delivers human-like accuracy in converting speech to text – complete with correct punctuation, capitalization, and word-level timestamps.

Key Technical Advantages
This XL variant processes audio segments up to 24 minutes long in a single pass using full attention mechanisms, eliminating the need for chunking. With an RTFx score of 3380 (batch size 128) on the HF-Open-ASR leaderboard, it balances high throughput and precision. Performance scales based on audio duration and batch size, making it adaptable for diverse deployment scenarios.
