Free Voice Calculator
Free Voice Calculator is a modern, free calculator extension that lives in your Chrome toolbar. Perform quick calculations directly from the extension popup using either traditional buttons or your voice.
Just click the microphone, speak naturally, and the extension will interpret your request — even in conversational language. It supports Italian, English, Spanish and French, with smart handling of numbers, decimals, simple fractions and percentages.
Whether you’re working with prices, discounts, small conversions or everyday math, you can get instant answers without opening a separate app or leaving the page you’re on. Voice recognition is handled locally by your browser via the Web Speech API, so no personal data is sent to external servers.

The extension is designed for natural, spoken math in multiple languages. Example phrases:
- “How much is 27.4 divided by 4.3?”
