+# Kotoba-Whisper-v1.1
+_Kotoba-Whisper-v1.1_ is a Japanese ASR model based on [kotoba-tech/kotoba-whisper-v1.0](https://huggingface.co/kotoba-tech/kotoba-whisper-v1.0), with 
+additional postprocessing stacks integrated as [`pipeline`](https://huggingface.co/docs/transformers/en/main_classes/pipelines). The new features includes 
+(i) improved timestamp achieved by [stable-ts](https://github.com/jianfch/stable-ts) and (ii) adding punctuation with [punctuators](https://github.com/1-800-BAD-CODE/punctuators/tree/main). 
+These libraries are merged into Kotoba-Whisper-v1.1 via pipeline and will be applied seamlessly to the predicted transcription from [kotoba-tech/kotoba-whisper-v1.0](https://huggingface.co/kotoba-tech/kotoba-whisper-v1.0).
+The pipeline has been developed through the collaboration between [Asahi Ushio](https://asahiushio.com) and [Kotoba Technologies](https://twitter.com/kotoba_tech)
+
+## Transformers Usage
+Kotoba-Whisper-v1.1 is supported in the Hugging Face 🤗 Transformers library from version 4.39 onwards. To run the model, first 
+install the latest version of Transformers.
+
+```bash
+pip install --upgrade pip
+pip install --upgrade transformers accelerate
+```
+
+### Transcription
+The model can be used with the [`pipeline`](https://huggingface.co/docs/transformers/main_classes/pipelines#transformers.AutomaticSpeechRecognitionPipeline)
+class to transcribe audio files as follows:
+
+```python
+import torch
+from transformers import pipeline
+from datasets import load_dataset
+
+# config
+model_id = "kotoba-tech/kotoba-whisper-v1.1"
+torch_dtype = torch.float16 if torch.cuda.is_available() else torch.float32
+device = "cuda:0" if torch.cuda.is_available() else "cpu"
+model_kwargs = {"attn_implementation": "sdpa"} if torch.cuda.is_available() else {}
+generate_kwargs = {"language": "japanese", "task": "transcribe"}
+
+# load model
+pipe = pipeline(
+    model=model_id,
+    torch_dtype=torch_dtype,
+    device=device,
+    model_kwargs=model_kwargs,
+    chunk_length_s=15,
+    batch_size=16
+)
+
+# load sample audio
+dataset = load_dataset("japanese-asr/ja_asr.reazonspeech_test", split="test")
+sample = dataset[0]["audio"]
+
+# run inference
+result = pipe(sample, return_timestamps=True, generate_kwargs=generate_kwargs)
+print(result)
+```
+
+- To transcribe a local audio file, simply pass the path to your audio file when you call the pipeline:
+```diff
+- result = pipe(sample, return_timestamps=True, generate_kwargs=generate_kwargs)
++ result = pipe("audio.mp3", return_timestamps=True, generate_kwargs=generate_kwargs)
+```
+
+### Transcription with Prompt
+Kotoba-whisper can generate transcription with prompting as below:
+
+```python
+import re
+import torch
+from transformers import pipeline
+from datasets import load_dataset
+
+# config
+model_id = "kotoba-tech/kotoba-whisper-v1.1"
+torch_dtype = torch.float16 if torch.cuda.is_available() else torch.float32
+device = "cuda:0" if torch.cuda.is_available() else "cpu"
+model_kwargs = {"attn_implementation": "sdpa"} if torch.cuda.is_available() else {}
+generate_kwargs = {"language": "japanese", "task": "transcribe"}
+
+# load model
+pipe = pipeline(
+    model=model_id,
+    torch_dtype=torch_dtype,
+    device=device,
+    model_kwargs=model_kwargs,
+    chunk_length_s=15,
+    batch_size=16
+)
+
+# load sample audio
+dataset = load_dataset("japanese-asr/ja_asr.reazonspeech_test", split="test")
+
+# --- Without prompt ---
+text = pipe(dataset[10]["audio"], generate_kwargs=generate_kwargs)['text']
+print(text)
+# 81歳、力強い走りに変わってきます。
+
+# --- With prompt ---: Let's change `81` to `91`.
+prompt = "91歳"
+generate_kwargs['prompt_ids'] = pipe.tokenizer.get_prompt_ids(prompt, return_tensors="pt").to(device)
+text = pipe(dataset[10]["audio"], generate_kwargs=generate_kwargs)['text']
+# currently the pipeline for ASR appends the prompt at the beginning of the transcription, so remove it
+text = re.sub(rf"\A\s*{prompt}\s*", "", text)
+print(text)
+# あっぶったでもスルガさん、91歳、力強い走りに変わってきます。
+```
+
+### Flash Attention 2
+We recommend using [Flash-Attention 2](https://huggingface.co/docs/transformers/main/en/perf_infer_gpu_one#flashattention-2) 
+if your GPU allows for it. To do so, you first need to install [Flash Attention](https://github.com/Dao-AILab/flash-attention):
+
+```
+pip install flash-attn --no-build-isolation
+```
+
+Then pass `attn_implementation="flash_attention_2"` to `from_pretrained`:
+
+```diff
+- model_kwargs = {"attn_implementation": "sdpa"} if torch.cuda.is_available() else {}
++ model_kwargs = {"attn_implementation": "flash_attention_2"} if torch.cuda.is_available() else {}
+```
