Keep Consonants Together at the Start

Say 'school' and listen closely to your own start. If you hear a tiny vowel sneaking in before the s, like 'iss-kool', that's a very natural habit since Bengali syllables don't usually begin with consonant clusters. English, though, is full of these clusters — 'spoon', 'street', 'small' — and they need to stay tightly packed together with no vowel breaking them up. Try this: say 'sss' as a long hiss first, then attach the rest of the word without any pause or extra sound — 'ssss-chool' becomes 'school'. Practice 'spoon', 'street', and 'small' this way, starting with the hiss and sliding straight into the cluster. Spend two minutes today doing this slowly, then speeding up while keeping the vowel out. Once your mouth learns to jump straight into these clusters, your words will sound crisper and closer to the target.
