The Science of Speaking
Fluency Tool combines the proven "Shadowing" technique with our proprietary EchoFluency Cycle to build automaticity and confidence.
What is Shadowing?
Shadowing is a language learning technique where you listen to native audio and repeat it almost simultaneously—like a shadow.
It forces your brain to process sounds at native speed, training your mouth muscles to reproduce the correct rhythm, intonation, and pitch accent without translating in your head.
The EchoFluency Cycle
We evolved shadowing into a complete 4-step system designed to overcome speaking anxiety:
- 1InputAbsorb native audio with matching text.
- 2RecordSpeak in a judgment-free, private environment.
- 3PlaybackSelf-assess your pitch and pronunciation.
- 4StrengthenReinforce with AI feedback and repetition.
