🧠 Dixtral — BUT-FIT Diarization-Conditioned Voxtral for Target-Speaker ASR

This repository hosts Dixtral, developed by BUT Speech@FIT. 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 target-speaker / multi-talker transcription (TS-ASR) of conversational and meeting recordings. For spoken question answering, use Dixtral_QA instead.

🛠️ Model Usage

from transformers import AutoModel, AutoProcessor

MODEL_NAME = "BUT-FIT/Dixtral"
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.
