The paper reports Alkhder’s submission to Subtask 1 of the AlexandriaX-2026 shared task, translating English dialogue turns into thirteen Arabic dialects. The team fine‑tuned NileChat‑3B‑Base with QLoRA on the Alexandria parallel dialogue corpus, training a single set of adapter weights for all dialects. Each translation is conditioned on target country, dialect, domain, participant roles, speaker‑addressee gender direction, and preceding dialogue context, and the model is run autoregressively using its own previous outputs as context. In the constrained track, training takes about one hour and inference on the private test set takes under two hours, achieving a country‑macro‑averaged spBLEU of 20.36 and chrF++ of 36.64 on both tracks.

GigaSpeech 3 is a new Arabic speech corpus comprising 39,000 hours and 10 million weakly transcribed segments across Algerian, Egyptian, Iraqi, Saudi, and Syrian dialects. It is built from 60 hours of manual transcription per dialect, using self‑supervised labeling models and noisy‑student refinement to produce high‑quality data. The corpus enables dialect‑specific and multi‑dialect speech recognition models that outperform existing third‑party systems, achieving a macro‑average word error rate of 23.86% for dialect‑specific models and 25.51% for a multi‑dialect model.
This study evaluates large language models (LLMs) for English‑to‑dialectal Arabic machine translation using the MADAR dataset across 16 Arabic dialects, covering both translation directions. It compares specialized Arabic models (Jais, Nile), multilingual models (Gemma, Command‑R, Mistral, Aya), and commercial APIs (GPT‑4.1) with multiple metrics—BLEU, CHRF, COMET, GEMBA—and a small manual assessment. The authors also examine LLMs’ ability to classify dialects and discuss challenges in automatic MT evaluation for Arabic dialects, noting potential training data contamination.
