Computer voice control has moved a long way from its beginning routes and in today's age controlling your PC with voice is truly a reality and fully possible. Voice control is taking up the steam in everyday life, from simple commands in cars, Alexa, smartphones, TVs, etc. to modern computers.

Windows 10 has introduced voice control into PC with Cortana even during the installation process but a lot has changed from having a virtual assistant in begging days and in today's modern Windows 11 OS. You can now freely open apps, move, copy delete files, and even dictate in order to create a word document.

However, in order to take this advantage, you will need to turn it off first since it is disabled by default. Of course, you will need a microphone and some spare time to train Windows in understanding you properly.

Setting up Voice Control

Just like in Windows 10, in Windows 11 voice control is also in accessibility options and the first step is to turn ON Windows Speech Recognition.

Click on the Start button and type Settings into the search bar, click on Open, or press ENTER. On the left side of the settings, window locate and click on Accessibility. On the right part once Accessibility is selected scroll down and find a section titled Interaction and click on Speech. Turn on the switch next to Windows Speech Recognition.

A pop-up will appear that will lead you through the rest of the setup and that's it.

Improving Voice Control

In order to make your voice control better, if you are not satisfied with the results, you can sample more of your voice into the algorithm to tune it more to your liking. Sadly this option is still deep in Control Panel.

Click the Start button and type in Speech recognition into the search bar, look for the search result with Control Panel displayed under it, and click on Open. Click on Train Your Computer to Better Understand You and follow the instructions.

The process will probably take a few minutes. The more data you provide to the speech recognition model, the more accurate it will be when interpreting your instructions. You can train the model multiple times, and each time you do, it should improve the accuracy.
