What VoiceCalc is
A calculator that takes speech as input. Say the calculation the way you would say it to a person, and the recognized expression appears above the answer, so misheard numbers are visible and correctable.
The web version is free and handles spoken arithmetic, percentages, powers and roots, plus unit, currency and time conversions. The iOS app extends into AI territory: word problems and multi-step reasoning.
What you can do with it
- Speak calculations like a person, no operator syntax
- Compare prices and compute discounts while shopping
- Split bills with tips and percentages
- Convert units, currencies and time zones by voice
- Hear answers read aloud on the web
- Ask word problems in the iOS app
Who it is for
- Shoppers comparing deals on the spot
- People who find typing numbers fiddly
- Accessibility users preferring voice interaction
- Anyone needing quick practical math
What to watch out for
- Speech recognition mishears numbers; the visible transcription exists for a reason
- Financially significant calculations deserve a second check by hand
- The AI word-problem features live in the paid iOS unlock
- Noisy environments degrade recognition
