This is a disappointing set of CDs and put together without much thought for the student. The main purpose of language CDs should surely be to allow the learner first of all to pronounce the language properly and then to listen over and over again to native speakers talking in the language. These CDs fail on both counts. They start with interminable pronunciation exercises that bear no relation to anything in the book and are pretty much pointless since words should be pronounced in context rather than as isolated entities. You are then supposedly taught the alphabet, but the pronunciation is not indicated anywhere phonetically in writing (e.g. hak for H, etc.), so you're left out on a limb when asked to spell certain words. When the text actually gets going, it immediately starts off at normal conversational speed, so the beginner has no opportunity to work on pronunciation any more or to grasp the principles of elision, and, to make matters worse, 'realistic' background noise is often added, obscuring what the speakers are actually saying. But my main quibble is the never-relenting presence of explanatory material in English, all of which could and should have been included in the textbook rather than on the discs. Almost half the duration of the discs is taken up with wholly unnecessary and unwanted explanations in English, and because of this the discs simply don't bear repeated listening. Material on the discs should in my opinion be restricted entirely to material in Catalan so that one can listen to it over and over again in order to accustom oneself to the language. There was no audio material attached to Alan Yates' earlier (1975) version of Teach Yourself Catalan, which was essentially a grammar book of a type familiar to anyone who has ever studied Latin. The new edition is more user-friendly although considerably updated and 'dumbed-down' from the earlier version. The audio material really is most unsatisfactory though and far inferior to the material on the Catalan course (textbook in French with audio material exclusively in Catalan) published by Assimil. Mr Yates has published an absolutely outstanding book entitled 'Catalan: A Comprehensive Grammar', but the efforts of the TY people to create something more accessible in the TY series are a disappointment.
