It's a half hour of audio each day. The key is that you speak out loud. You can do it while cooking or driving, or any other activity that is routine and non-verbal.
They teach you to pronounce phrases very well, and you learn the basic structure of the language. Once you can say "I would like a glass of wine", you can easily learn to say "I would like X".
When I got to Italy, people thought I had been living there for a year.
There are only two things you MUST do:
1. Do a lesson every day. 2. Speak out loud, in a normal conversational tone. The program is teaching you to have conversations.
I love these courses so much that I'm compelled to gush about them whenever language learning is mentioned. They won't make you a native speaker, but you'll quickly reach a level where you can advance rapidly.
