Answer:
It depends on what language you want to translate. For example if you speak English as your first language but you know Spanish as your second language you may want to be a translator for Spanish. So you would listen to them and then translate what they say in Spanish into English and then when the other person says something in English you translate it for the other man into Spanish. Do you understand? I hope so!! They don't have many but you have to learn what language you want to translate and you can do a few if you want I believe.
