# Whisper large-v3 model for CTranslate2 |
|
|
|
This repository contains the conversion of Whisper `large-v3` to the [CTranslate2](https://github.com/OpenNMT/CTranslate2) model format. |
|
|
|
This model can be used in CTranslate2 or projects based on CTranslate2 such as [faster-whisper](https://github.com/guillaumekln/faster-whisper). |
|
|
|
## Example |
|
|
|
```python |
|
from faster_whisper import WhisperModel |
|
|
|
model = WhisperModel("flyingleafe/faster-whisper-large-v3") |
|
|
|
segments, info = model.transcribe("audio.mp3") |
|
for segment in segments: |
|
print("[%.2fs -> %.2fs] %s" % (segment.start, segment.end, segment.text)) |
|
``` |
|
|
|
## Conversion details |
|
|
|
The original model was converted the following way: |
|
|
|
``` |
|
# use Transformers convertation to HF format |
|
python transformers/src/transformers/models/whisper/convert_openai_to_hf.py \ |
|
--checkpoint_path large-v3 --pytorch_dump_folder_path ./whisper-large-v3 --convert_tokenizer True |
|
|
|
# ... some manual convertation to get `tokenizer.json` via `WhisperTokenizerFast` class ... |
|
|
|
ct2-transformers-converter --model ./whisper-large-v3 --output_dir faster-whisper-large-v2 \ |
|
--copy_files tokenizer.json preprocessor_config.json --quantization float16 |
|
``` |
|
|
|
|
|
Note that the model weights are saved in FP16. This type can be changed when the model is loaded using the [`compute_type` option in CTranslate2](https://opennmt.net/CTranslate2/quantization.html). |
