Setup Voice control in Windows11

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.

voice control

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.

File is Too Large for the Destination Error
The file is too large for the destination file system is the error when you try to copy a file larger than 4GB on a drive formatted in the FAT32 file system. FAT32 is the old file system used in previous Windows versions and it was replaced by superior NTFS, altho FAT32 is still used because of its compatibility fact that it could be accessed in various operating systems its disadvantage among others is that it can not hold files larger than 4GB in size. This refers to the size of a single file, so if you have a file that is this large and when you try to copy or move it on a drive formatted in FAT32 you will get this message, and the operation will not be able to complete.

Format drive

In order to actually transfer the file in its glorious size, I am afraid that you will need to format destination drive in NTFS or if you have data on drive which you do not want to lose with formatting, use third-party software to convert file system from FAT32 to NTFS without losing data. I would recommend AOMEI partition assistant, it is a free and proven application letting you both manage your partitions and convert any one of them into another file system without data loss. You can get AOMEI here.

Split file

Another option if you are not keen on installing third-party tools or formating is to divide large files into smaller ones that are less than 4GB in size. You can use any archiving application since built-in Windows ZIP support will not let you split file into various different sizes. The best tool in my humble opinion is WinRAR, but you can choose any proven one. When file is split into parts less than 4GB in size, you will have no issues copying or move the file to the destination drive.
