# Guides
emotion2vec+ is a series of foundational models for speech emotion recognition (SER). We aim to train a "whisper" in the field of speech emotion recognition, overcoming the effects of language and recording environments through data-driven methods to achieve universal, robust emotion recognition capabilities. The performance of emotion2vec+ significantly exceeds other highly downloaded open-source models on Hugging Face.

This version (emotion2vec_plus_base) uses a large-scale pseudo-labeled data for finetuning to obtain a base size model (~90M),  and currently supports the following categories:
0: angry
1: disgusted
2: fearful
3: happy
4: neutral
5: other
6: sad
7: surprised
8: unknown

# Data Iteration

We offer 3 versions of emotion2vec+, each derived from the data of its predecessor. If you need a model focusing on spech emotion representation, refer to [emotion2vec: universal speech emotion representation model](https://huggingface.co/emotion2vec/emotion2vec).

- emotion2vec+ seed: Fine-tuned with academic speech emotion data from [EmoBox](https://github.com/emo-box/EmoBox)
- emotion2vec+ base: Fine-tuned with filtered large-scale pseudo-labeled data to obtain the base size model (~90M)
- emotion2vec+ large: Fine-tuned with filtered large-scale pseudo-labeled data to obtain the large size model (~300M)

The iteration process is illustrated below, culminating in the training of the emotion2vec+ large model with 40k out of 160k hours of speech emotion data. Details of data engineering will be announced later. 

# Installation

`pip install -U funasr modelscope`

# Usage

input: 16k Hz speech recording

granularity:
- "utterance": Extract features from the entire utterance
- "frame": Extract frame-level features (50 Hz)

extract_embedding: Whether to extract features; set to False if using only the classification model

## Inference based on ModelScope

```python
from modelscope.pipelines import pipeline
from modelscope.utils.constant import Tasks

inference_pipeline = pipeline(
    task=Tasks.emotion_recognition,
    model="iic/emotion2vec_plus_base")

rec_result = inference_pipeline('https://isv-data.oss-cn-hangzhou.aliyuncs.com/ics/MaaS/ASR/test_audio/asr_example_zh.wav', granularity="utterance", extract_embedding=False)
print(rec_result)
```


## Inference based on FunASR

```python
from funasr import AutoModel

model = AutoModel(model="iic/emotion2vec_plus_base")

wav_file = f"{model.model_path}/example/test.wav"
res = model.generate(wav_file, output_dir="./outputs", granularity="utterance", extract_embedding=False)
print(res)
```
Note: The model will automatically download.


Supports input file list, wav.scp (Kaldi style):
```cat wav.scp
wav_name1 wav_path1.wav
wav_name2 wav_path2.wav
...
```

Outputs are emotion representation, saved in the output_dir in numpy format (can be loaded with np.load())

# Note

This repository is the Huggingface version of emotion2vec, with identical model parameters as the original model and Model Scope version.
