What this means for learners
Sango and Burushaski share 24 sounds — roughly 41% of Burushaski's inventory overlaps with Sango. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 35 sounds found only in Burushaski represent the greatest pronunciation challenge for Sango 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, Sango has 20 sounds not used in Burushaski. Native Burushaski speakers learning Sango will face the mirror-image challenge with these sounds.
