# 🧠 Dixtral_QA — BUT-FIT Diarization-Conditioned Voxtral for Spoken QA

This repository hosts **Dixtral_QA**, developed by [BUT Speech@FIT](https://github.com/BUTSpeechFIT). 
**Dixtral** couples the **Voxtral-Mini-3B** spoken-language model with the **DiCoW** diarization-conditioned encoder, giving the LLM target-speaker awareness in multi-talker audio.

This checkpoint is tuned for **spoken question answering** over conversational/meeting audio. For pure target-speaker transcription, use [**Dixtral_TS-ASR**](https://huggingface.co/BUT-FIT/Dixtral_TS-ASR) instead.

## 🛠️ Model Usage

```python
from transformers import AutoModel, AutoProcessor

MODEL_NAME = "BUT-FIT/Dixtral_QA"
model = AutoModel.from_pretrained(MODEL_NAME, trust_remote_code=True)
processor = AutoProcessor.from_pretrained(MODEL_NAME)
```

➡️ For full inference pipelines (diarization → FDDT masks → generation), see the
[**Dixtral GitHub repository**](https://github.com/BUTSpeechFIT/Dixtral).
