# wav2vec2-large-xlsr-53-dutch

GGUF quantizations of [jonatasgrosman/wav2vec2-large-xlsr-53-dutch](https://huggingface.co/jonatasgrosman/wav2vec2-large-xlsr-53-dutch) for use with [wav2vec2.cpp](https://github.com/liodon-ai/wav2vec2.cpp).

## Files

| Filename | Quant | Size | Precision |
|----------|-------|------|-----------|
| `model_f16.gguf`  | F16  | 631 MB  | ~fp16 (near-lossless) |
| `model_q8_0.gguf` | Q8_0 | 373 MB | 8-bit quantized linear layers |
| `model_q4_0.gguf` | Q4_0 | 222 MB | 4-bit quantized linear layers |

## Parity vs HuggingFace Reference

Tested on 10 audio samples from FLEURS nl_nl.

| Quant | Mean CER (vs HF) | Mean WER (vs HF) | Status |
|-------|-----------------|-----------------|--------|
| F16   | 0.00%  | 0.00%  | PASS |
| Q8_0  | 0.10% | 0.60% | PASS |
| Q4_0  | 1.51% | 9.67% | PASS |

CER/WER measured against HF model output (not ground truth) to isolate quantization error.

## Usage

### C++ CLI

```bash
# Clone and build
git clone --recursive https://github.com/liodon-ai/wav2vec2.cpp
cd wav2vec2.cpp && mkdir build && cd build && cmake .. && make -j

# Download and run
huggingface-cli download liodon-ai/wav2vec2-large-xlsr-53-dutch-GGUF model_q8_0.gguf --local-dir .
./wav2vec2-cli -m model_q8_0.gguf -f audio.wav

# With word timestamps
./wav2vec2-cli -m model_q8_0.gguf -f audio.wav -w

# SRT subtitle output
./wav2vec2-cli -m model_q8_0.gguf -f audio.wav --format srt > output.srt
```

### Python (via subprocess)

```python
import subprocess, json
result = subprocess.run(
    ['./wav2vec2-cli', '-m', 'model_q8_0.gguf', '-f', 'audio.wav', '--format', 'json'],
    capture_output=True, text=True
)
data = json.loads(result.stdout)
print(data['transcript'])
```
