Paul Noble’s audiobook series is for beginners or upper-beginners who want to gain confidence in their target language. There are also crash courses for those who will soon be heading off on a business trip or holiday. The series focuses on cognates (words that are similar in both English and your target language) in order to build your vocabulary more efficiently. It also seems to have been inspired by Michel Thomas’ courses (with a few improvements).
Paul introduces vocabulary and gets you to make new sentences through problem solving. For example, he may introduce a sentence, then ask you to make a new sentence using your current knowledge and the new words you have just learned. Although the narrators move a bit slowly, the consistent interaction between you and the material ensures that you won’t get bored. Because Paul breaks down the rules of each language in such a simple and concise way, you can feel confident in building new sentences by yourself.
