What this means for learners

The 20 sounds found only in ISOKO represent the greatest pronunciation challenge for English (New Zealand) 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.
