Use with `vad_model` + `spk_model` + `punc_model` to get per-sentence speaker labels. Requires installing FunASR from source: `pip install git+https://github.com/modelscope/FunASR.git` - 2024/11: Add support for timestamp based on the CTC alignment. - 2024/7: Added Export Features for [ONNX](./demo_onnx.py) and [libtorch](./demo_libtorch.py), as well as Python Version Runtimes: [funasr-onnx-0.4.0](https://pypi.org/project/funasr-onnx/), [funasr-torch-0.1.1](https://pypi.org/project/funasr-torch/) - 2024/7: The [SenseVoice-Small](https://www.modelscope.cn/models/iic/SenseVoiceSmall) voice understanding model is open-sourced, which offers high-precision multilingual speech recognition, emotion recognition, and audio event detection capabilities for Mandarin, Cantonese, English, Japanese, and Korean and leads to exceptionally low inference latency. - 2024/7: The CosyVoice for natural speech generation with multi-language, timbre, and emotion control. CosyVoice excels in multi-lingual voice generation, zero-shot voice generation, cross-lingual voice cloning, and instruction-following capabilities. [CosyVoice repo](https://github.com/FunAudioLLM/CosyVoice) and [CosyVoice space](https://www.modelscope.cn/studios/iic/CosyVoice-300M). - 2024/7: [FunASR](https://github.com/modelscope/FunASR) is a fundamental speech recognition toolkit that offers a variety of features, including speech recognition (ASR), Voice Activity Detection (VAD), Punctuation Restoration, Language Models, Speaker Verification, Speaker Diarization and multi-talker ASR. <a name="Benchmarks"></a> # Benchmarks 📝 ## Multilingual Speech Recognition We compared the performance of multilingual speech recognition between SenseVoice and Whisper on open-source benchmark datasets, including AISHELL-1, AISHELL-2, Wenetspeech, LibriSpeech, and Common Voice. In terms of Chinese and Cantonese recognition, the SenseVoice-Small model has advantages. <div align="center"> <img src="image/asr_results1.png" width="400" /><img src="image/asr_results2.png" width="400" /> </div> ## Speech Emotion Recognition Due to the current lack of widely-used benchmarks and methods for speech emotion recognition, we conducted evaluations across various metrics on multiple test sets and performed a comprehensive comparison with numerous results from recent benchmarks. The selected test sets encompass data in both Chinese and English, and include multiple styles such as performances, films, and natural conversations. Without finetuning on the target data, SenseVoice was able to achieve and exceed the performance of the current best speech emotion recognition models. <div align="center"> <img src="image/ser_table.png" width="1000" /> </div> Furthermore, we compared multiple open-source speech emotion recognition models on the test sets, and the results indicate that the SenseVoice-Large model achieved the best performance on nearly all datasets, while the SenseVoice-Small model also surpassed other open-source models on the majority of the datasets. <div align="center"> <img src="image/ser_figure.png" width="500" /> </div> ## Audio Event Detection Although trained exclusively on speech data, SenseVoice can still function as a standalone event detection model. We compared its performance on the environmental sound classification ESC-50 dataset against the widely used industry models BEATS and PANN. The SenseVoice model achieved commendable results on these tasks. However, due to limitations in training data and methodology, its event classification performance has some gaps compared to specialized AED models. <div align="center"> <img src="image/aed_figure.png" width="500" /> </div> ## Computational Efficiency The SenseVoice-Small model deploys a non-autoregressive end-to-end architecture, resulting in extremely low inference latency. With a similar number of parameters to the Whisper-Small model, it infers more than 5 times faster than Whisper-Small and 15 times faster than Whisper-Large. <div align="center"> <img src="image/inference.png" width="1000" /> </div> # Requirements ```shell pip install -r requirements.txt ``` <a name="Usage"></a> # Usage ## Inference Supports input of audio in any format and of any duration. ```python from funasr import AutoModel from funasr.utils.postprocess_utils import rich_transcription_postprocess model_dir = "iic/SenseVoiceSmall" model = AutoModel( model=model_dir, trust_remote_code=True, remote_code="./model.py", vad_model="fsmn-vad", vad_kwargs={"max_single_segment_time": 30000}, device="cuda:0", ) # en res = model.generate( input=f"{model.model_path}/example/en.mp3", cache={}, language="auto", # "zh", "en", "yue", "ja", "ko", "nospeech" use_itn=True, batch_size_s=60, merge_vad=True, # merge_length_s=15, ) text = rich_transcription_postprocess(res[0]["text"]) print(text) ``` <details><summary>Parameter Description (Click to Expand)</summary> - `model_dir`: The name of the model, or the path to the model on the local disk. - `trust_remote_code`: - When `True`, it means that the model's code implementation is loaded from `remote_code`, which specifies the exact location of the `model` code (for example, `model.py` in the current directory). It supports absolute paths, relative paths, and network URLs. - When `False`, it indicates that the model's code implementation is the integrated version within [FunASR](https://github.com/modelscope/FunASR). At this time, modifications made to `model.py` in the current directory will not be effective, as the version loaded is the internal one from FunASR. For the model code, [click here to view](https://github.com/modelscope/FunASR/tree/main/funasr/models/sense_voice). - `vad_model`: This indicates the activation of VAD (Voice Activity Detection). The purpose of VAD is to split long audio into shorter clips. In this case, the inference time includes both VAD and SenseVoice total consumption, and represents the end-to-end latency. If you wish to test the SenseVoice model's inference time separately, the VAD model can be disabled. - `vad_kwargs`: Specifies the configurations for the VAD model. `max_single_segment_time`: denotes the maximum duration for audio segmentation by the `vad_model`, with the unit being milliseconds (ms). - `use_itn`: Whether the output result includes punctuation and inverse text normalization. - `batch_size_s`: Indicates the use of dynamic batching, where the total duration of audio in the batch is measured in seconds (s). - `merge_vad`: Whether to merge short audio fragments segmented by the VAD model, with the merged length being `merge_length_s`, in seconds (s). - `ban_emo_unk`: Whether to ban the output of the `emo_unk` token. </details> ### Speaker Diarization SenseVoice supports speaker diarization when used with VAD + CAM++ speaker model + punctuation model: ```python from funasr import AutoModel from funasr.utils.postprocess_utils import rich_transcription_postprocess model = AutoModel( model="iic/SenseVoiceSmall", trust_remote_code=True, remote_code="./model.py", vad_model="fsmn-vad", vad_kwargs={"max_single_segment_time": 30000}, spk_model="cam++", punc_model="ct-punc", device="cuda:0", ) res = model.generate( input="example.wav", cache={}, language="auto", use_itn=True, batch_size_s=60, merge_vad=True, merge_length_s=15, ) # Per-sentence results with speaker labels for sent in res[0]["sentence_info"]: text = rich_transcription_postprocess(sent["text"]) print(f"Speaker {sent['spk']}: [{sent['start']}ms - {sent['end']}ms] {text}") ``` > Note: Requires installing FunASR from source: `pip install git+https://github.com/modelscope/FunASR.git` If all inputs are short audios (<30s), and batch inference is needed to speed up inference efficiency, the VAD model can be removed, and `batch_size` can be set accordingly. ```python model = AutoModel(model=model_dir, trust_remote_code=True, device="cuda:0") res = model.generate( input=f"{model.model_path}/example/en.mp3", cache={}, language="zh", # "zh", "en", "yue", "ja", "ko", "nospeech" use_itn=False, batch_size=64, ) ``` For more usage, please refer to [docs](https://github.com/modelscope/FunASR/blob/main/docs/tutorial/README.md) ### Inference directly Supports input of audio in any format, with an input duration limit of 30 seconds or less. ```python from model import SenseVoiceSmall from funasr.utils.postprocess_utils import rich_transcription_postprocess model_dir = "iic/SenseVoiceSmall" m, kwargs = SenseVoiceSmall.from_pretrained(model=model_dir, device="cuda:0") m.eval() res = m.inference( data_in=f"{kwargs['model_path']}/example/en.mp3", language="auto", # "zh", "en", "yue", "ja", "ko", "nospeech" use_itn=False, ban_emo_unk=False, **kwargs, ) text = rich_transcription_postprocess(res[0][0]["text"]) print(text) ``` ### Export and Test <details><summary>ONNX and Libtorch Export</summary> #### ONNX ```python # pip3 install -U funasr funasr-onnx from pathlib import Path from funasr_onnx import SenseVoiceSmall from funasr_onnx.utils.postprocess_utils import rich_transcription_postprocess model_dir = "iic/SenseVoiceSmall" model = SenseVoiceSmall(model_dir, batch_size=10, quantize=True) # inference wav_or_scp = ["{}/.cache/modelscope/hub/{}/example/en.mp3".format(Path.home(), model_dir)] res = model(wav_or_scp, language="auto", use_itn=True) print([rich_transcription_postprocess(i) for i in res]) ``` Note: ONNX model is exported to the original model directory. #### Libtorch ```python from pathlib import Path from funasr_torch import SenseVoiceSmall from funasr_torch.utils.postprocess_utils import rich_transcription_postprocess model_dir = "iic/SenseVoiceSmall" model = SenseVoiceSmall(model_dir, batch_size=10, device="cuda:0") wav_or_scp = ["{}/.cache/modelscope/hub/{}/example/en.mp3".format(Path.home(), model_dir)] res = model(wav_or_scp, language="auto", use_itn=True) print([rich_transcription_postprocess(i) for i in res]) ``` Note: Libtorch model is exported to the original model directory. </details> ## Service ### Deployment with FastAPI ```shell export SENSEVOICE_DEVICE=cuda:0 fastapi run --port 50000 ``` ## Finetune ### Requirements ```shell git clone https://github.com/alibaba/FunASR.git && cd FunASR pip3 install -e ./ ``` ## 🐳 Docker Support SenseVoice can be built and run using Docker to simplify setup, ensure reproducibility, and support both CPU and GPU inference. ### Build with Docker ```bash docker build -t sensevoice . ``` ### Run (GPU – default) ```bash docker run --gpus all -p 50000:50000 sensevoice ``` ### Run (CPU-only) ```bash docker run -e SENSEVOICE_DEVICE=cpu -p 50000:50000 sensevoice ``` ### Docker Compose Docker Compose provides an easier way to run SenseVoice with persistent model caching, networking etc. ### Start Stack ```bash docker compose up --build ``` ### Data prepare Data examples ```text {"key": "YOU0000008470_S0000238_punc_itn", "text_language": "<|en|>", "emo_target": "<|NEUTRAL|>", "event_target": "<|Speech|>", "with_or_wo_itn": "<|withitn|>", "target": "Including legal due diligence, subscription agreement, negotiation.", "source": "/cpfs01/shared/Group-speech/beinian.lzr/data/industrial_data/english_all/audio/YOU0000008470_S0000238.wav", "target_len": 7, "source_len": 140} {"key": "AUD0000001556_S0007580", "text_language": "<|en|>", "emo_target": "<|NEUTRAL|>", "event_target": "<|Speech|>", "with_or_wo_itn": "<|woitn|>", "target": "there is a tendency to identify the self or take interest in what one has got used to", "source": "/cpfs01/shared/Group-speech/beinian.lzr/data/industrial_data/english_all/audio/AUD0000001556_S0007580.wav", "target_len": 18, "source_len": 360} ``` Full ref to `data/train_example.jsonl` <details><summary>Data Prepare Details</summary> Description： -
