# HuBERT Emotion Recognition Model

Fine-tuned HuBERT model for emotion recognition in speech audio.

## Model Description

This model classifies speech audio into 5 emotion categories:

1. **Angry/Fearful** - Expressions of anger or fear
2. **Happy/Laugh** - Joyful or laughing expressions  
3. **Neutral/Calm** - Neutral or calm speech
4. **Sad/Cry** - Expressions of sadness or crying
5. **Surprised/Amazed** - Surprised or amazed reactions

## Quick Start

```python
from transformers import pipeline

# Load the model
classifier = pipeline("audio-classification", model="YOUR_USERNAME/hubert-emotion-recognition")

# Predict emotion
result = classifier("audio.wav")
print(result)
```

## Detailed Usage

```python
from transformers import AutoModelForAudioClassification, Wav2Vec2FeatureExtractor
import torch
import librosa

# Load model and processor
model = AutoModelForAudioClassification.from_pretrained("YOUR_USERNAME/hubert-emotion-recognition")
processor = Wav2Vec2FeatureExtractor.from_pretrained("YOUR_USERNAME/hubert-emotion-recognition")

# Load audio (16kHz)
audio, sr = librosa.load("audio.wav", sr=16000)

# Prepare inputs
inputs = processor(audio, sampling_rate=16000, return_tensors="pt")

# Get predictions
with torch.no_grad():
    outputs = model(**inputs)
    probs = torch.softmax(outputs.logits, dim=1)[0]
    pred_id = torch.argmax(probs).item()

# Show results
emotions = ["Angry/Fearful", "Happy/Laugh", "Neutral/Calm", "Sad/Cry", "Surprised/Amazed"]
print(f"Emotion: {emotions[pred_id]}")
print(f"Confidence: {probs[pred_id]:.3f}")
```
