# Emotion Recognition in Turkish Speech using HuBERT
This HuBERT model is trained on [TurEV-DB](https://github.com/Xeonen/TurEV-DB) to achieve speech emotion recognition (SER) in Turkish.

## How to use

### Requirements

```bash
# requirement packages
!pip install git+https://github.com/huggingface/datasets.git
!pip install git+https://github.com/huggingface/transformers.git
!pip install torchaudio
!pip install librosa
```

```bash
!git clone https://github.com/SeaBenSea/HuBERT-SER.git
```

### Prediction

```python
import sys  
sys.path.insert(1, './HuBERT-SER/')
import torch
import torch.nn as nn
import torch.nn.functional as F
import torchaudio
from transformers import AutoConfig, Wav2Vec2FeatureExtractor
from src.models import Wav2Vec2ForSpeechClassification, HubertForSpeechClassification
```

```python
model_name_or_path = "SeaBenSea/hubert-large-turkish-speech-emotion-recognition"

device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
config = AutoConfig.from_pretrained(model_name_or_path)
feature_extractor = Wav2Vec2FeatureExtractor.from_pretrained(model_name_or_path)
sampling_rate = feature_extractor.sampling_rate

model = HubertForSpeechClassification.from_pretrained(model_name_or_path).to(device)
```

```python
def speech_file_to_array_fn(path, sampling_rate):
    speech_array, _sampling_rate = torchaudio.load(path)
    resampler = torchaudio.transforms.Resample(_sampling_rate, sampling_rate)
    speech = resampler(speech_array).squeeze().numpy()
    return speech


def predict(path, sampling_rate):
    speech = speech_file_to_array_fn(path, sampling_rate)
    inputs = feature_extractor(speech, sampling_rate=sampling_rate, return_tensors="pt", padding=True)
    inputs = {key: inputs[key].to(device) for key in inputs}

    with torch.no_grad():
        logits = model(**inputs).logits

    scores = F.softmax(logits, dim=1).detach().cpu().numpy()[0]
    outputs = [{"Emotion": config.id2label[i], "Score": f"{round(score * 100, 3):.1f}%"} for i, score in
               enumerate(scores)]
    return outputs
```

```python
path = "../dataset/TurEV/Angry/1157_kz_acik.wav"
outputs = predict(path, sampling_rate)
outputs
```

```bash
[
  {'Emotion': 'Angry', 'Score': '99.8%'},
  {'Emotion': 'Calm', 'Score': '0.0%'},
  {'Emotion': 'Happy', 'Score': '0.1%'},
  {'Emotion': 'Sad', 'Score': '0.1%'}
]
```


## Evaluation
The following tables summarize the scores obtained by model overall and per each class.


|  Emotions | precision | recall | f1-score | accuracy |
|:---------:|:---------:|:------:|:--------:|:--------:|
|   Angry   |    0.97   |  0.99  |   0.98   |          |
|   Calm    |    0.89   |  0.95  |   0.92   |          |
|   Happy   |    0.98   |  0.93  |   0.95   |          |
|   Sad     |    0.97   |  0.93  |   0.95   |          |
|           |           |        |  Overal  |   0.95   |
