What this means for learners
Arabic and Kota share 13 sounds — roughly 32% of Kota's inventory overlaps with Arabic. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 28 sounds found only in Kota represent the greatest pronunciation challenge for Arabic speakers. The adult brain tends to map unfamiliar sounds onto the closest native equivalent — a process that produces the characteristic "accent" of a second-language speaker. Learning to hear and produce these sounds as distinct requires focused ear training, not just repetition.
Conversely, Arabic has 24 sounds not used in Kota. Native Kota speakers learning Arabic will face the mirror-image challenge with these sounds.
