How It Understands

Turning sound into the right words is trickier than it looks. Words are made of little sound-pieces called phonemes — and the AI uses a language model to guess what makes sense, because lots of words sound the same!

🔤 Step 1 · Sound It Out

Words are made of sound-pieces

Every word is a chain of little sounds (phonemes). Tap the pieces left-to-right, then blend them into the whole word and hear it. Complete 3 words!

👂 Step 2 · Same Sound, Different Word

"I scream" or "ice cream"?

Lots of words sound exactly the same! So how does the AI know which you meant? It uses the context — the other words around it. Read each sentence and pick the word that makes sense.

🔮 Step 3 · The Language Model

Guess the sensible next word

The AI's language model guesses which word fits best — that's how it fixes mistakes and picks real words over nonsense. Be the language model: pick the word that makes sense!
