+# Whisper kotoba-whisper-v2.0 model for CTranslate2
+
+This repository contains the conversion of [kotoba-tech/kotoba-whisper-v2.0](https://huggingface.co/kotoba-tech/kotoba-whisper-v2.0) 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/systran/faster-whisper).
+
+## Example
+Install library and download sample audio.
+```shell
+pip install faster-whisper
+wget https://huggingface.co/kotoba-tech/kotoba-whisper-v2.0-ggml/resolve/main/sample_ja_speech.wav
+```
+Inference with the kotoba-whisper-v2.0-faster.
+
+```python
+from faster_whisper import WhisperModel
+
+model = WhisperModel("kotoba-tech/kotoba-whisper-v2.0-faster")
+
+segments, info = model.transcribe("sample_ja_speech.wav", language="ja", chunk_length=15, condition_on_previous_text=False)
+for segment in segments:
+    print("[%.2fs -> %.2fs] %s" % (segment.start, segment.end, segment.text))
+```
+
+### Benchmark
+Please refer to the [kotoba-tech/kotoba-whisper-v1.0-faster](https://huggingface.co/kotoba-tech/kotoba-whisper-v1.0-faster) for the detail of speed up [here](https://huggingface.co/kotoba-tech/kotoba-whisper-v1.0-faster#benchmark).
+
+
+
+## Conversion details
+
+The original model was converted with the following command:
+
+```
+ct2-transformers-converter --model kotoba-tech/kotoba-whisper-v2.0 --output_dir kotoba-whisper-v2.0-faster \
+    --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).
+
+## More information
