What this means for learners
ALAMBLAK and Dafla share 10 sounds — roughly 37% of Dafla's inventory overlaps with ALAMBLAK. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 17 sounds found only in Dafla represent the greatest pronunciation challenge for ALAMBLAK 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, ALAMBLAK has 15 sounds not used in Dafla. Native Dafla speakers learning ALAMBLAK will face the mirror-image challenge with these sounds.
