Voice recognition can help people with their writing. Google Docs offers Built-in Voice typing and Google Chrome is available on various systems (Windows, Mac, Chromebook). There is no voice training required like other speech recognition software. This allows you to talk directly to your computer without even needing a microphone headset. Of course it is recommended that you use it without too much background noise and speak directly to your computer’s built in microphone. You can also use voice commands (i.e. Insert header) to edit documents.
If you have not used Google Docs, it is recommended to install Chrome browser (download link: https://www.google.com/chrome/browser/desktop/index.html) and follow the next steps to access Google Docs.
