Windows Speech Recognition lets you control your PC with your voice alone, without needing a keyboard or mouse. There's a wizard to help you get started. Just plug in your microphone, and then, in the search box on the taskbar, type Speech Recognition, and select Windows Speech Recognition.
Beginning with the Windows 10 Fall Creators Update, you can also convert spoken words into text anywhere on your PC with dictation.
After you complete the wizard, you can walk through a tutorial to learn voice commands and train your PC to recognize your voice.
For additional options, type Control Panel in the search box on the taskbar, and select Control Panel. Then select Ease of Access > Speech Recognition.
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.
