Arabic Orpheus TTS Fine-tuning

Fine-tuning unsloth/orpheus-3b-0.1-ft for Arabic speech synthesis using a 2-stage pipeline:

1. Multi-speaker Arabic adaptation
2. Single-speaker specialization

Highlights

• Formal Arabic / MSA-oriented output
• 2-stage LoRA fine-tuning
• Arabic text normalization
• SNAC-based audio tokenization
• Demo audio samples included

Important note on data

The training dataset is not included in this repository.

I used licensed/restricted data and cannot redistribute:

• raw audio
• metadata
• transcriptions
• processed dataset artifacts derived from the source corpus

This repository only contains the training/inference code, configuration, and demo outputs.

Training setup

• Base model: unsloth/orpheus-3b-0.1-ft
• Stage 1: Arabic multi-speaker training
• Stage 2: single-speaker fine-tuning on a female voice
• Hardware used: L40S
• LoRA fine-tuning with Unsloth
