For example you are in Germany and German people are talking in Germany's language which is not Urdu and English probably. So you need to speak English, you need to set the output language too and so it will translate into German language for the one you are translating for. Then will click on the Microphone button and he will reply in German language and so your phone will translate it into English for you.
Example: You To Phone: Which street directs to Kassel?
German: will speak in German language, meanwhile when he finish speaking, then your phone will speak sentence(s) in English.
