What this means for learners
SAMA and Bugis share 17 sounds — roughly 53% of Bugis's inventory overlaps with SAMA. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 8 sounds found only in Bugis represent the greatest pronunciation challenge for SAMA 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, SAMA has 15 sounds not used in Bugis. Native Bugis speakers learning SAMA will face the mirror-image challenge with these sounds.
