I found purchasing Eric B. Shumway's "Intensive Course in Tongan" tapes, very helpful as a student wanting to learn the Tongan language. Although buying the book with the tapes is a necessity. I found the readings on the tapes to be very clear and easy to follow along with. The reader gives you plenty of time to repeat after them, which is very effective in learning. Also the songs and readings are very entertaining. This is a good buy for a serious Tongan language learning student. Also these are the only Tongan language tapes I could find out there.
