Parakeet TDT 0.6B v3

Parakeet TDT 0.6B v3 (August 2025, Hugging Face nvidia/parakeet-tdt-0.6b-v3, technical report arXiv 2509.14128) is the multilingual successor in NVIDIA's Parakeet line: a 600M FastConformer encoder with a Token-and-Duration Transducer decoder, expanded from English-only v2 to 25 European languages with automatic language detection — no prompting needed. It emits punctuated, capitalized transcripts with word- and segment-level timestamps and handles up to 24 minutes of audio in a single pass. NVIDIA pairs it with Canary-1B-v2 (the 1B sibling covering ASR plus speech-to-text translation), and the report claims Canary-1B-v2 beats Whisper-large-v3 on English ASR at 10x the speed with competitive multilingual ASR/AST against Seamless-M4T-v2-large. Community CPU benchmarks back the speed story (~2.16% WER on LibriSpeech test-clean at ~20x real-time). The whole thing is CC-BY-4.0, so it's genuinely usable commercially — the go-to open replacement for Whisper in European-language transcription pipelines.

• Canary-1B-v2 outperforms Whisper-large-v3 on English ASR at 10x speed (author-reported, arXiv 2509.14128)\n- Community CPU benchmark: 2.16% WER on LibriSpeech test-clean, ~0.05 RTF (independent, small-scale)\n- Competitive multilingual ASR/AST vs Seamless-M4T-v2-large (author-reported)
