The 21 sounds found only in Karen represent the greatest pronunciation challenge for SEDANG 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, SEDANG has 37 sounds not used in Karen. Native Karen speakers learning SEDANG will face the mirror-image challenge with these sounds.
