What this means for learners
Kanuri and Kota share 19 sounds — roughly 46% of Kota's inventory overlaps with Kanuri. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 22 sounds found only in Kota represent the greatest pronunciation challenge for Kanuri 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, Kanuri has 16 sounds not used in Kota. Native Kota speakers learning Kanuri will face the mirror-image challenge with these sounds.
