Only in Punjabi 48
What this means for learners
Punjabi and Bhumij share 25 sounds — roughly 34% of Bhumij's inventory overlaps with Punjabi. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 29 sounds found only in Bhumij represent the greatest pronunciation challenge for Punjabi 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, Punjabi has 48 sounds not used in Bhumij. Native Bhumij speakers learning Punjabi will face the mirror-image challenge with these sounds.
