Shared sounds 41
What this means for learners
Sindhi and Siraiki share 41 sounds — roughly 49% of Siraiki's inventory overlaps with Sindhi. Shared sounds are ones a speaker already knows from their native language and will generally produce and perceive accurately without explicit training.
The 42 sounds found only in Siraiki represent the greatest pronunciation challenge for Sindhi 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, Sindhi has 23 sounds not used in Siraiki. Native Siraiki speakers learning Sindhi will face the mirror-image challenge with these sounds.
