What this means for learners
Kyrgyz and Dafla share 10 sounds — roughly 27% of Dafla's inventory overlaps with Kyrgyz. 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 Kyrgyz 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, Kyrgyz has 27 sounds not used in Dafla. Native Dafla speakers learning Kyrgyz will face the mirror-image challenge with these sounds.
