# Highlights 🎯

**SenseVoice** focuses on high-accuracy multilingual speech recognition, speech emotion recognition, and audio event
detection.

- **Multilingual Speech Recognition:** Trained with over 400,000 hours of data, supporting more than 50 languages, the
  recognition performance surpasses that of the Whisper model.
- **Rich transcribe:**
    - Possess excellent emotion recognition capabilities, achieving and surpassing the effectiveness of the current best
      emotion recognition models on test data.
    - Offer sound event detection capabilities, supporting the detection of various common human-computer interaction
      events such as bgm, applause, laughter, crying, coughing, and sneezing.
- **Efficient Inference:** The SenseVoice-Small model utilizes a non-autoregressive end-to-end framework, leading to
  exceptionally low inference latency. It requires only 70ms to process 10 seconds of audio, which is 15 times faster
  than Whisper-Large.
- **Convenient Finetuning:** Provide convenient finetuning scripts and strategies, allowing users to easily address
  long-tail sample issues according to their business scenarios.
- **Service Deployment:** Offer service deployment pipeline, supporting multi-concurrent requests, with client-side
  languages including Python, C++, HTML, Java, and C#, among others.

# 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>

## 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.

<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.

# Requirements

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 = "FunAudioLLM/SenseVoiceSmall"


model = AutoModel(
    model=model_dir,
    vad_model="fsmn-vad",
    vad_kwargs={"max_single_segment_time": 30000},
    device="cuda:0",
    hub="hf",
)

# en
res = model.generate(
    input=f"{model.model_path}/example/en.mp3",
    cache={},
    language="auto",  # "zn", "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)
```

Parameter Description:

- `model_dir`: The name of the model, or the path to the model on the local disk.
- `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).

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, device="cuda:0", hub="hf")

res = model.generate(
    input=f"{model.model_path}/example/en.mp3",
    cache={},
    language="zh", # "zn", "en", "yue", "ja", "ko", "nospeech"
    use_itn=False,
    batch_size=64, 
    hub="hf",
)
```

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 = "FunAudioLLM/SenseVoiceSmall"
m, kwargs = SenseVoiceSmall.from_pretrained(model=model_dir, device="cuda:0", hub="hf")
m.eval()

res = m.inference(
    data_in=f"{kwargs['model_path']}/example/en.mp3",
    language="auto", # "zn", "en", "yue", "ja", "ko", "nospeech"
    use_itn=False,
    **kwargs,
)

text = rich_transcription_postprocess(res[0][0]["text"])
print(text)
```
