Change one thing about your mouth.
Hear a new sound appear.
This isn’t a recording — your device is synthesising the sound live from the shape of a mouth. Drag the dot inside the box: up/down changes how open your jaw is, left/right changes where your tongue sits. Every spot is a real vowel. No sound is recorded, and no audio leaves your device.
Press and drag inside the box to morph the vowel. Tap a labelled dot to hear a known vowel. Each dot also shows your Bengali vowel (বাংলা স্বর) — watch where English splits one of yours into two. 🔊 turn your volume up.
Now try consonants
Same trick, different air. Tap one — then flip the switch and feel how voicing turns s→z, f→v. (This is the same voicing you feel buzz in Missions.)
Every English consonant
Tap any sound. It opens into whichever vowel the pad is sitting on — drag the pad first and the same consonant changes with it, exactly like কে → কা. The blue letter is the বাংলা বর্ণ your mouth already makes it with — and where you see a 🔊 word below a key, that is a real Bengali voice from Kolkata saying it, not the computer.
A blue letter means your mouth already makes that sound in বাংলা. A letter with * means বাংলা writes it with that letter, but the sound itself is new — the letter can mislead you. NEW means no বাংলা letter makes it at all. The * and NEW sounds are the ones worth practising.
Sounds that move
বাংলা vowels are pure — they hold still. These eight English sounds slide from one vowel to another. Tap one and watch the dot travel across the pad: if your mouth does not move with it, the sound flattens — that is the single commonest slip.
যুক্তবর্ণ — where two letters become one
বাংলা joins letters into a single shape: ক + ষ → ক্ষ, স + ত → স্ত, ঙ + গ → ঙ্গ. English does the same thing with sounds — street, desked, splash — clusters your mouth must run together without slipping a vowel in between. We are building the bridge between the two, so the যুক্তবর্ণ you already read becomes the way you say English clusters.
Not built yet — these are shown so you can see where this is going. বর্ণপরিচয় teaches যুক্তবর্ণ after the simple letters, and so will we.
