INTRODUCTION_TEXT = """
📖**Universal Arabic ASR Leaderboard (Extended Edition)**📖 is a fork of the [Open Universal Arabic ASR Leaderboard](https://github.com/Natural-Language-Processing-Elm/open_universal_arabic_asr_leaderboard), extended to benchmark **both open-source and closed-source** multi-dialect Arabic ASR models on various multi-dialect datasets.
\nWhile the original leaderboard is dedicated exclusively to open-source models, this fork broadens the scope to include commercial/closed-source providers such as **ElevenLabs, OpenAI, Deepgram, Microsoft**, and others — enabling a more comprehensive comparison across the Arabic ASR landscape.
\nApart from the WER%/CER% for each test set, we also report the Average WER%/CER% and rank the models based on the Average WER, from lowest to highest.
\nFor more context on the motivation behind this fork, see the [original discussion](https://github.com/Natural-Language-Processing-Elm/open_universal_arabic_asr_leaderboard/issues/5).
\nFor more detailed analysis such as models' robustness, speaker adaption, model efficiency and memory usage, please check the original [paper](https://arxiv.org/pdf/2412.13788).

## Metrics
We report both the Word Error Rate (WER) and Character Error Rate (CER) metrics.
## Reproduction
The Open Universal Arabic ASR Leaderboard will be a continuous benchmark project. 
\nWe open-source the evaluation scripts at our [GitHub repo](https://github.com/Natural-Language-Processing-Elm/open_universal_arabic_asr_leaderboard).
\nPlease launch a discussion in our GitHub repo to let us know if you want to learn about the performance of a new model.
