There are many latin letters that don't exist in this alphabet,for example,q is actually a strong r,while r is a soft one;c has the spanish ch sound,and ñ (you can only use it if you have a spanish keyboard,sorry) is replaced by the sh sound;there are also 3 extra vowels:y (long i/russian й),w (even more closed spanish u,or woo if you speak english) and a schwa (you can use it by typing the letter h);also,every vowels has its accented version (á,é,í,ý,ó,ú,w and h can be used by typing ü and ö respectively)
