Voice Calculator: Talking Math

Say an entire calculation and hear the answer. Voice Calculator combines a talking calculator with voice input: say “twenty percent of five hundred” or “square root of eighty-one”, then see the expression, get the result and hear it read aloud.

SPEAK THE WHOLE PROBLEM
• Say numbers and operations together in a natural phrase instead of tapping every digit.
• Voice input understands English and Urdu. It also understands Roman Urdu number words, including million, billion, lakh and crore.
• Voice recognition depends on the speech service available on your phone. English voice input works offline on many devices when the right speech data is installed.

HEAR EVERY ANSWER
• The calculator reads results aloud. Spoken key presses are optional.
• Set voice speed, volume and voice type to match your preference.
• Prefer typing? Use the large keypad. Keypad calculations, history and spoken answers work offline.

FROM DAILY MATH TO SCIENTIFIC FUNCTIONS
Calculate a shopping discount, restaurant tip, tax percentage or markup. For school, work and more advanced sums, use square roots, powers, factorials, sin, cos, tan, log, ln and pi by voice or keypad. Brackets help organize an expression.

FIX AN EXPRESSION IN PLACE
Enter a sum on the large keypad with brackets and percent. Tap anywhere in the expression to edit it, then use undo or redo to reverse or restore a change. You can correct a typo without clearing the whole calculation.

REUSE PAST CALCULATIONS
Your calculation history is stored on your device and grouped by day. Tap an earlier expression to use it again. There is no account to create, and your history stays on your phone.

ACCESSIBLE BY DESIGN
Large buttons, screen-reader labels and haptic feedback can make the calculator easier to use for blind and low-vision users, older adults and people who prefer larger controls. Listen to answers instead of relying only on the screen, and adjust the speech to a comfortable pace and volume.

SIMPLE, PRIVATE AND COMPLETE
Pick a light, dark or AMOLED theme. There is no account or tracking, and data stays on your device. Every feature is included without in-app purchases. Use it for quick household sums, shopping, tips, taxes, homework, work or scientific calculations.
