What this means for learners
TEKE and Balinese share 20 sounds — roughly 71% of Balinese's inventory overlaps with TEKE. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 4 sounds found only in Balinese represent the greatest pronunciation challenge for TEKE 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, TEKE has 8 sounds not used in Balinese. Native Balinese speakers learning TEKE will face the mirror-image challenge with these sounds.
