What this means for learners
Kabiyɛ and Lak share 18 sounds — roughly 26% of Lak's inventory overlaps with Kabiyɛ. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 51 sounds found only in Lak represent the greatest pronunciation challenge for Kabiyɛ 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, Kabiyɛ has 29 sounds not used in Lak. Native Lak speakers learning Kabiyɛ will face the mirror-image challenge with these sounds.
