What this means for learners
Maung and Sa'ban share 15 sounds — roughly 33% of Sa'ban's inventory overlaps with Maung. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 31 sounds found only in Sa'ban represent the greatest pronunciation challenge for Maung 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, Maung has 9 sounds not used in Sa'ban. Native Sa'ban speakers learning Maung will face the mirror-image challenge with these sounds.
