Assamese Self-Taught Book

Just beginning -- it's fun :O) buuut, not entirely reader-friendly, for an american speaker. The shop people say it's mostly for speakers from the various Indian regions. I trust that they are enjoying the book, with greater ease. Still, while I may add a zero, after the '30' -- as in 'Learn Sanskrit in 300 Days', or maybe I'll skip the '3' digit entirely, haha, a dbl zero days..right now, on day number 2, this is for fun. The pronunciations are not clear, to an english speaker: For example, words that end with an "h" are actually ended with the sounds of 'ha'. There are various degrees of hard and soft sounds, when voicing the 'g' and also the 'k' sounds...this might work very well, as a CD or cassette set, much easier to be accurate, instead of embarasssing (with a do-able '30 days').
