Only in Bhojpuri 30
What this means for learners
Bhojpuri and Yao share 21 sounds — roughly 41% of Yao's inventory overlaps with Bhojpuri. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 28 sounds found only in Yao represent the greatest pronunciation challenge for Bhojpuri 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, Bhojpuri has 30 sounds not used in Yao. Native Yao speakers learning Bhojpuri will face the mirror-image challenge with these sounds.
