You're listening. You miss one word — three more slip past.

While you're stuck on one, the rest keeps moving. TonesFly breaks that cycle. Add any audio and it becomes a live lesson — phrases pause so you can breathe, words appear in sync so you can see what you heard, and you can finally start keeping up.

👇Press and hold to listen

You're in the middle of a sentence.
You hear a word you don't know. Then what?

What usually happens
“So I’ll start with this: a couple years ago, an event planner called me”
Your brain: "Wait — what was that word?"
The audio: keeps going without you.
Result: 3 more words gone while you were stuck on 1.
With TonesFly
“So I’ll start with this: a couple years ago, an event planner called me”
The audio pauses at the phrase boundary. You have time to process.
Tap the dashes to reveal the words you missed.
No words lost. You stay with the conversation.

Miss one word — lose the rest.

One unfamiliar word slows you down. The speaker keeps going. By the time you recover, the sentence is already over. That's your Cognitive Span: how long you can hold on before comprehension starts to slip.

Without space
Y entonces me dijo que
no iba a poder venir
Ah bueno, no pasa nada.
The sentence keeps moving. You lose the thread.
With space between phrases
Y entonces me dijo que
no iba a poder venir
Ah bueno, no pasa nada.
Same speech. Just enough room to keep up.
