Only in Telugu 55
What this means for learners
Telugu and SEDANG share 13 sounds — roughly 19% of SEDANG's inventory overlaps with Telugu. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 42 sounds found only in SEDANG represent the greatest pronunciation challenge for Telugu 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, Telugu has 55 sounds not used in SEDANG. Native SEDANG speakers learning Telugu will face the mirror-image challenge with these sounds.
