Description reportthebug 2026-02-10 17:24:16 UTC 
Support Mistral AI’s new open-weight Voxtral models as an alternative STT engine for automatic subtitling.

Key Benefits:
* Higher Accuracy: Outperforms Whisper Large-v3 in speed and Word Error Rate (WER).
* Native Diarization: Built-in speaker identification to automatically label different voices in transcripts.
* Efficiency: Optimized for local hardware; the Mini-3B model provides high-quality results with low VRAM usage.
* Privacy/License: Apache 2.0 license, allowing for fully offline, private processing.

Proposed Integration:
Add "Voxtral" to the STT engine list in Settings > Speech to Text, with model selection (Mini/Small) and a toggle for speaker diarization.
