How will I know when it’s my turn to speak?

During the conversation, you will see the text on the screen. Your lines will be written in white. Your virtual conversation practice partner’s lines will be a little pale. Say your lines out loud, first as person B, then wait for your virtual conversation practice partner to speak then say your lines again, just like a real conversation! After this, you will switch and you will be Person A.              
When you are person A, you have to be ready to start speaking immediately because the first line in the conversation will be yours. After doing the conversation 3 times with the text on the screen, you’ll do the same again three times without the help of any text.
