Shared sounds 35
What this means for learners
Konkani and Kumauni share 35 sounds — roughly 78% of Kumauni's inventory overlaps with Konkani. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 7 sounds found only in Kumauni represent the greatest pronunciation challenge for Konkani 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, Konkani has 10 sounds not used in Kumauni. Native Kumauni speakers learning Konkani will face the mirror-image challenge with these sounds.
