# mlx-community/emotion2vec-plus-large-mlx

The **emotion2vec+ large** speech-emotion-recognition model converted to MLX format for native
inference on Apple Silicon, consumed by the [`xocialize/emotion2vec-mlx-swift`](https://github.com/xocialize/emotion2vec-mlx-swift)
Swift port. Refer to the [original model card](https://huggingface.co/emotion2vec/emotion2vec_plus_large)
for details.

## Model

- **Family:** emotion2vec / emotion2vec+ (Ma et al., "emotion2vec: Self-Supervised Pre-Training for Speech Emotion Representation," [arXiv:2312.15185](https://arxiv.org/abs/2312.15185))
- **Architecture:** Data2Vec 2.0 — conv feature extractor → transformer encoder → 9-class linear head
- **Output:** 9-class categorical emotion (`angry`, `disgusted`, `fearful`, `happy`, `neutral`, `other`, `sad`, `surprised`, `unknown`)
- **Sample rate:** 16000 Hz, mono
- **Precision:** fp16 (233 tensors)

## Files

- `emotion2vec_large.safetensors` — the MLX weights (fp16).
- `emotion2vec_large_config.json` — model config consumed by the loader.

## Usage (Swift / MLX)

```swift
import Emotion2VecMLX
import Hub

let dir = try await HubApi().snapshot(from: "mlx-community/emotion2vec-plus-large-mlx")
let recogniser = try await EmotionRecogniser(weightsDirectory: dir,
                                             config: EmotionRecogniserConfig(models: .categorical))
let result = try await recogniser.classify(audioURL: speechURL)
print(result.categorical.label, result.categorical.confidence)
```
