Hi. I'm David, and I'm happy to help you.
According to reputation information I found online, AISControlService.exe is a background process that comes bundled with certain audio drivers, developed by "AI Speech Co. Ltd". It resides in the Windows system directory and is generally safe. Like any executable, its legitimacy depends on both its origin and location.
When found in C:\Windows\System32\DriverStore, the file is almost certainly genuine and part of the official driver package, not malware.
Feel free to ask back any questions.
