2] Choose the correct keyboard

First, press Win+I to open the Windows Settings panel. Then, go to Time & language > Languages & region.
Select the language, click on the three-dotted icon, and select the Language options.
Then, click on the Add a keyboard button and try selecting the Phonetic keyboard layout.

There is plenty of third-party typing software available in the market that helps you type regional languages in different apps. As they offer more options and flexibility, many users often install them on their computers. If you have done something like that, it is recommended to temporarily disable the software and check if it resolves the issue.

4] Select the desired language from system tray

No matter how many languages you have enabled to type on your computer, you need to choose the language manually to start typing. There are mainly two options to select the desired language: from the system tray or the Taskbar.
First, you can use the keyboard shortcut, which is Win+Space. However, the problem arises when you have five or six languages. In that case, you need to keep pressing the set of shortcuts.
If you want to know a shortcut method, you can click on the language bar visible on the Taskbar and choose a language as per your requirements.

5] Check Advanced keyboard settings

The Advanced keyboard settings in the Windows Settings panel help you override the default input method. In other words, if you want to opt for a specific language instead of showing the language bar in the Taskbar, this option is for you. From the opposite perspective, if you enable this setting, you cannot type in another language, regardless of whether it is a regional language or not.
To check the Advanced keyboard settings, follow these steps:
First, open the Windows Settings panel by pressing Win+I. Then, go to Time & language > Typing > Advanced keyboard settings.
After that, expand the Override for default input method drop-down menu, and select the Use language list option.
