What this means for learners
KANAKURU and Kimeru share 19 sounds — roughly 54% of Kimeru's inventory overlaps with KANAKURU. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 8 sounds found only in Kimeru represent the greatest pronunciation challenge for KANAKURU 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, KANAKURU has 16 sounds not used in Kimeru. Native Kimeru speakers learning KANAKURU will face the mirror-image challenge with these sounds.
