Arabic (MSA) ASR datasets
Modern Standard Arabic is read aloud rather than spoken natively, so every recording carries the phonology of the reader's own dialect underneath it. The /q/, /θ/ and /dʒ/ sounds in particular come out differently depending on where the reader learned to speak. Whether the transcript follows the written form or the actual pronunciation has to be stated, because the two diverge on nearly every sentence.
What ASR work in Arabic (MSA) requires
Transcription convention, decided first
Whether to write what was said or what should have been said is the single biggest source of disagreement between annotators. For this language the two diverge often enough that the convention has to be explicit.
Speaker count over hours
Recognition models overfit to voices faster than to vocabulary. A dataset that is long but narrow will test well on held-out audio from the same speakers and fail on anyone new.
Noise that matches deployment
If the model will run on phone audio in a city, training on studio recordings creates a mismatch that no amount of additional clean data fixes.
The mistake that costs the most
The most common mistake is specifying hours without specifying speakers, and then discovering at evaluation time that the model only works on the people who were recorded.
The language-specific factor
Almost nobody speaks Modern Standard Arabic as a native, everyday language. The practical result of recording standard Arabic is that every speaker carries their own dialect accent: unless the speaker's dialect background and the tolerated deviation are defined up front, annotation consistency collapses.
