The lessons on this podcast are nicely self-contained. You can listen to the dialog for each lesson while looking at the transcript, which is conveniently available by pressing the center button on your iPod, but the "read slowly" and "jetzt mit überseztung" (with translation) parts enable in-car or while-working-out German learning. After the dialog, they give some cultural insights, which are also handy, and often a lesson on grammar (which are quite useful). Then they translate many of the words in the dialog and conjugate verbs, which is sometimes is too literal (rather than sticking to the meaning in the dialog, they often include other meanings). The woman (Judith) is native German, but her English pronunciation is clear and she has a very nice voice. She knows vocabulary and grammar very well and explains the cultural insights plainly. The man (Chuck) also has a nice voice and has thankfully improved a lot in his pronunciation. He can now be relied upon as an example of pronunciation (he pronounces Ich as "Ish", but that is normal for many Germans). The dialogs used to sound like the misadventures of an ignorant American, but he/they have thankfully have stopped making his misunderstandings part of the lessons.
I am considering signing up for the paid service, which includes a "premium feed" and other lesson materials, but I don't really want to hear any of the older lessons, which were horrible - Chuck used to butcher German with an off-putting American accent and frequently mispronounced words.
