You should watch soap operas on YouTube, because you won't be able to meet Germans every single evening, and you won't be able to ask them to repeat what they said 20 times until you have perfected the pronunciation of standard phrases,like greetings and farewells. With videos on YouTube,however, you can play back single sentences over and over again. Soap operas are especially good, because you get to know the characters, their personalities, and their way of speaking - their favourite expressions. For example, in Arabic: "Bas tadreen shlon?!" There is one soap opera specially for learners of German. It's called "Jojo sucht das Glück". Search for it on YouTube. It has subtitles, and the subtitles are in German, so you can stop the video at any time and replay bits of speech so you can practice saying what the actor just said, and you can see how to write it as well. I do this when I'm learning Arabic. Just watch lots and lots of episodes of your favourite soap opera. For example, in Arabic, the character says "Madri sh a gullak", but there are no subtitles, but still I can work out that must be: "Ma adri aish a gullak", but he said it quickly. To copy him you have to replay the video of that one phrase over and over again, until you can visualise every consonant and vowel as if they were hanging in the air in front of your eyes. Then you can work on the intonation of the voice - how the tone rises and falls during the phrase, and whthere there are slight pauses within the phrase. After much practice you will begin to sound like a native speaker.
