Only in Tigre 42
What this means for learners
Tigre and Kota share 12 sounds — roughly 22% of Kota's inventory overlaps with Tigre. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 29 sounds found only in Kota represent the greatest pronunciation challenge for Tigre 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, Tigre has 42 sounds not used in Kota. Native Kota speakers learning Tigre will face the mirror-image challenge with these sounds.
