Rosetta Stone takes a lot of guess work and to me that is a waste of time. This audiobook makes so much sense and I was making sentences that I can retain after the first two chapters. I speak English and Spanish and working on Italian and Portuguese through this same author. I wish I knew about this audiobook when I was learning Spanish.
You will not be disappointed with this audiobook. Rosetta Stone uses a lot of marketing hype, but looking at pictures and trying to guess exactly what the picture is supposed to say is ridiculous.
"Alphabetical" is a pleasant read/listen, and, unlike many books about linguistics, seems well grounded in actual facts. Author Michael Rosen reads it marvelously in his British-but-not-posh accent. With this book you get an interesting and educational, if not very profound, look at alphabets and other phonetic/linguistic phenomena.
By the way, Rosen tells the reader to consult "the PDF" several times for written examples of alphabets, etc., which he refers to. This file can be found on the Audible.com page for this audiobook, at the end of the Publisher's Summary. Just click where it says "Download the accompanying reference guide."
