Only in Punjabi 62
What this means for learners
Punjabi and Garo share 11 sounds — roughly 15% of Garo'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 15 sounds found only in Garo 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 62 sounds not used in Garo. Native Garo speakers learning Punjabi will face the mirror-image challenge with these sounds.
