After the preview at I/O 2026 in May, Gemini for macOS is now rolling out advanced voice control capabilities. The first is intelligent dictation that transcribes “spoken words into clean, polished text.” Extract and summarize information : Highlight local files, images, or documents on your desktop and tell Gemini exactly what you need. Compose and rewrite text : Highlight text anywhere on your screen and use your voice to instantly rewrite it, tweak the tone, and drop the polished version right where you need it. This new voice capability is still rolling out globally to all users in English and more languages are “coming soon.”
