RUSLAN 1
This is additional material written by Vassily Bessonoff in Washington DC to accompany the North American edition of Ruslan 1. It is intended for those who want to make a specialist study of some of the finer points of Russian pronunciation.

This material will probably be most useful for experienced linguists who want to perfect their pronounciation. Do not struggle with it if you just want to be able to get by in the language to start with. You can always come back to it later!

There is a pdf file with explanations and there will be a sound file with recordings of the examples.
