Only in Lithuanian 44
What this means for learners
Lithuanian and Bhumij share 16 sounds — roughly 27% of Bhumij's inventory overlaps with Lithuanian. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 38 sounds found only in Bhumij represent the greatest pronunciation challenge for Lithuanian 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, Lithuanian has 44 sounds not used in Bhumij. Native Bhumij speakers learning Lithuanian will face the mirror-image challenge with these sounds.
