Arabic (MSA) TTS datasets
Standard Arabic script is normally written without the short-vowel marks, which leaves the reader to supply them. A speaker guessing at vowels produces a voice that mispronounces a predictable share of words, and the errors repeat. The script is fully vowel-marked before recording, and a reader who is not a native speaker of the dialect behind the text is rejected at the audition stage.
What TTS work in Arabic (MSA) requires
Speaker consistency across sessions
A voice recorded over several days drifts in pitch and pacing. If the target is one synthetic voice, either record in fewer, longer sessions or plan to re-record segments that fall outside tolerance.
Text the speaker can read fluently
A speaker reading unfamiliar script produces disfluencies that end up baked into the synthetic voice. Script selection matters as much as recording quality.
Phonetic coverage, not just volume
A long recording can still miss phonemes that are rare in running text. Coverage has to be checked against the language's inventory, not against word count.
The mistake that costs the most
The most common mistake is buying many hours from many speakers when the goal needed a few hours from one speaker, recorded properly.
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.
