Only in Wolof 36
What this means for learners
Wolof and SEDANG share 18 sounds — roughly 33% of SEDANG's inventory overlaps with Wolof. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 37 sounds found only in SEDANG represent the greatest pronunciation challenge for Wolof 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, Wolof has 36 sounds not used in SEDANG. Native SEDANG speakers learning Wolof will face the mirror-image challenge with these sounds.
