Plain Language Accessible to non-experts
Imagine a large language factory responsible for processing various Arabic dialects' speech inputs. Each dialect has its own production line, converting speech to text. This factory has a leaderboard to evaluate each production line's efficiency and accuracy. By comparing different production lines' performances, the factory can identify the best line for handling multi-dialect speech and optimize it.

Abstract
In recent years, the enhanced capabilities of ASR models and the emergence of multi-dialect datasets have increasingly pushed Arabic ASR model development toward an all-dialect-in-one direction. This trend highlights the need for benchmarking studies that evaluate model performance on multiple dialects, providing the community with insights into models' generalization capabilities. In this paper, we introduce Open Universal Arabic ASR Leaderboard, a continuous benchmark project for open-source general Arabic ASR models across various multi-dialect datasets. We also provide a comprehensive analysis of the model's robustness, speaker adaptation, inference efficiency, and memory consumption. This work aims to offer the Arabic ASR community a reference for models' general performance and also establish a common evaluation framework for multi-dialectal Arabic ASR models.
