When you are trying to learn a language with a different alphabet, it may take time until you familiarize yourself with the whole set of this new alphabet. The only way to make it easier is to practice and practice. 

In Langoid there is a tool to help us practice, which is the Reading tutorial. When you go to Reading, you can see a list of letters and also info about how to set up your keyboard to type in that language. In this page, you can listen to how a letter sounds, and how they will sound in a word. Then you can challenge yourself to guess what letter or word an audio is pronouncing. 

Try to do this exercise every day until you are familiar with all the letters and no longer need practice.
