Sound inventory comparison
What this means for learners
Nez Perce and Nyangumata share 13 sounds — roughly 36% of Nyangumata's inventory overlaps with Nez Perce. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 14 sounds found only in Nyangumata represent the greatest pronunciation challenge for Nez Perce 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, Nez Perce has 23 sounds not used in Nyangumata. Native Nyangumata speakers learning Nez Perce will face the mirror-image challenge with these sounds.
