From Mouth to Words on Screen
When you talk to Siri, Alexa, or a kid-safe AI, your voice gets translated. The sound waves turn into squiggly numbers. The numbers turn into letters. The letters turn into words. All in less than a second.
The 4-step magic trick
- 1Microphone catches sound waves
- 2Computer turns waves into numbers (digital)
- 3AI matches the numbers to sounds it has heard before
- 4Sounds become words on the screen
Accent and language
Voice AI used to only work great with one type of voice. Now it learns from people all over the world — kids, grown-ups, lots of accents and languages. The more voices it hears, the better it gets at understanding everyone.
