Only in IRANXE 26
What this means for learners
IRANXE and Burushaski share 13 sounds — roughly 22% of Burushaski's inventory overlaps with IRANXE. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 46 sounds found only in Burushaski represent the greatest pronunciation challenge for IRANXE 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, IRANXE has 26 sounds not used in Burushaski. Native Burushaski speakers learning IRANXE will face the mirror-image challenge with these sounds.
