When you set up Speech Recognition in Windows 10, it lets you control your PC with your voice alone, without needing a keyboard or mouse.
Using only your voice, you can open menus, click buttons and other objects on the screen, dictate text into documents, and write and send emails. Just about anything you do with your keyboard and mouse can be done with only your voice.
Speech Recognition is only available for the following languages: English (United States, United Kingdom, Canada, India, and Australia), French, German, Japanese, Mandarin (Chinese Simplified and Chinese Traditional), and Spanish.
You can choose to enable or disable voice activation mode for Speech Recognition.
Enable voice activation mode – Windows Speech Recognition turns off when you say the “Stop Listening” voice command, and must be turned on by clicking on the microphone button or pressing the Ctrl+Windows keys
Disable voice activation mode – Speech Recognition goes into sleep mode when not in use, and can be activated by saying the “Start Listening” voice command.
