Only in NENETS 26
What this means for learners
NENETS and Burushaski share 9 sounds — roughly 15% of Burushaski's inventory overlaps with NENETS. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 50 sounds found only in Burushaski represent the greatest pronunciation challenge for NENETS 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, NENETS has 26 sounds not used in Burushaski. Native Burushaski speakers learning NENETS will face the mirror-image challenge with these sounds.
