Voice Control gives your voice the power to navigate, dictate, and work your devices in a new way. Coming Fall 2019.
Introducing Voice Control. Your all-access to all devices.
macOS Catalina includes new features to help everyone get the most out of Mac. Voice Control lets users who don’t use traditional input devices control Mac, iPadOS, and iOS devices entirely with their voice. New tools for users with low vision allow them to zoom a second display or view high-resolution text for items below a cursor.
Voice Control
Easily navigate your Mac using just your voice. Improved dictation and richer text editing features make writing more efficient, while comprehensive commands let you open and interact with apps. Navigate an app with numbered labels next to clickable items, or by superimposing a grid to precisely select, zoom, and drag.
