What this means for learners
MANCHU and Kharia share 13 sounds — roughly 28% of Kharia's inventory overlaps with MANCHU. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 34 sounds found only in Kharia represent the greatest pronunciation challenge for MANCHU 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, MANCHU has 12 sounds not used in Kharia. Native Kharia speakers learning MANCHU will face the mirror-image challenge with these sounds.
