# Parakeet TDT test fixtures
- `2086-149220-0033.wav`
- 16 kHz mono, ~7.44 s speech clip, extracted from the LibriSpeech
`test-clean` corpus, utterance `2086-149220-0033`
("Well, I don't wish to see it any more, observed Phoebe, turning away
her eyes. It is certainly very like the old portrait.").
- LibriSpeech (Panayotov et al., 2015) is distributed under CC BY 4.0:
https://www.openslr.org/12
- Used by `test_golden_transcription.cpp` and
`test_streaming_transcription.cpp` as a fixed-input regression check for
offline full-context, bounded-window long-form, word timestamps, buffered
streaming, finalize, and reset. Both tests accept the installed
safetensors directory or a standalone GGUF through `--model`.
The expected transcription was verified against the actual NeMo
reference model (`nvidia/parakeet-tdt-0.6b-v3` via
`nemo.collections.asr.models.ASRModel.from_pretrained`) for this exact
clip, not just eyeballed.
