Only in Dan 76
What this means for learners
Dan and Lak share 16 sounds — roughly 17% of Lak's inventory overlaps with Dan. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 53 sounds found only in Lak represent the greatest pronunciation challenge for Dan 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, Dan has 76 sounds not used in Lak. Native Lak speakers learning Dan will face the mirror-image challenge with these sounds.
