# Whisper Large V3 CT2 — Word/Char Timestamps + Diarization Bundle
A single, self-contained ASR bundle: **faster-whisper / CTranslate2** transcription of
Whisper large-v3, plus **wav2vec2 forced alignment** for accurate per-word and per-char
timestamps, plus optional **pyannote speaker diarization**. Everything is resolved locally
from this directory — nothing is downloaded at runtime.
## Contents
| Path | Component | Purpose |
|---|---|---|
| `/` | Whisper large-v3 (CTranslate2, `int8_float16`-ready) | transcription engine |
| `aligners/en` | `wav2vec2-large-xlsr-53-english` | English word/char timestamps |
| `aligners/pl` | `wav2vec2-large-xlsr-53-polish` | Polish word/char timestamps |
| `aligners/multi` | `wav2vec2-xlsr-multilingual-56` | 56-language fallback aligner |
| `diarization/` | `speaker-diarization-community-1` | speaker labels (who spoke when) |

**Attribution (required):** the diarization weights are licensed **CC-BY-4.0** — commercial
use is permitted **with attribution** to *pyannote* (Hervé Bredin et al.) and the
`speaker-diarization-community-1` model card. Keep this notice on any redistribution.
The bundle is made available by **deAPI-ai** on Hugging Face, configured for integration
with **GamerHash AI's** platform. All credit for the underlying models belongs to their
respective creators listed above.
## Note on file formats
- `model.bin` is **CTranslate2's** own binary format (the transcription engine) — not a
PyTorch pickle.
- The aligners are stored as **safetensors**.
- `diarization/*/pytorch_model.bin` are **pyannote / PyTorch-Lightning** checkpoints; they
carry non-tensor hyperparameters that safetensors cannot hold, so they remain `.bin`
(identical to the official `pyannote/speaker-diarization-community-1` repo).
