What this means for learners
Angas and Burushaski share 22 sounds — roughly 37% of Burushaski's inventory overlaps with Angas. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 37 sounds found only in Burushaski represent the greatest pronunciation challenge for Angas 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, Angas has 22 sounds not used in Burushaski. Native Burushaski speakers learning Angas will face the mirror-image challenge with these sounds.
