What are the languages you don´t understand but know which language it is when spoken?

For example, i dont know any french or russian or german but whenever i hear it i can immediatelly say this is that language. How can we do it?

To be honest with you, Turkish. Since I´m still a beginner, when I hear someone speaking Turkish they speak really fast, so I can´t understand what they are saying, but I can immediately tell it´s Turkish. Also Italian and French.

Kurdish, French, Spanish, Hebrew, Persian, Indian (but I don´t know which of them since they have several languages) Maybe Filipino as well. 

Italian, French, Spanish, Portuguese, Romanian, German, Greek, Russian, Persian, Arabic, Chinese, Japanese, Serbian/Croat, Kurdish, English spoken by a Scottish/Aussie/American and can make some good guesses for some others (Polish,Dutch,Danish,Indian,Hungarian etc.).

Turkish, English, French, Italian, Spanish, Portuguese, Hungarian, Serbian, Polish, Czech, Russian, German (I can understand too the first 3)

french, german, spanish, italian, russian, japanese, chinese, korean, arabic, farsi, indian, and maybe portuguese, too
