Only in Páez 41
What this means for learners
Páez and Ket share 8 sounds — roughly 16% of Ket's inventory overlaps with Páez. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 24 sounds found only in Ket represent the greatest pronunciation challenge for Páez 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, Páez has 41 sounds not used in Ket. Native Ket speakers learning Páez will face the mirror-image challenge with these sounds.
