What this means for learners
English (New Zealand) and PO-AI share 12 sounds — roughly 27% of PO-AI's inventory overlaps with English (New Zealand). Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 23 sounds found only in PO-AI 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. Learning to hear and produce these sounds as distinct requires focused ear training, not just repetition.
Conversely, English (New Zealand) has 33 sounds not used in PO-AI. Native PO-AI speakers learning English (New Zealand) will face the mirror-image challenge with these sounds.
