Some pronunciation remarks on the performance, although it is very good:
tAnindrazanay= american people pronounce the a of tan- like the a in car and hard, malagasy people speak instead at the front of the mouth, not back like for cat, and sat,
taninDR- = american say nd-r ( like in he eats and runs away), you must pronounce it once -dr, -ndr like in drain
sometimes american people say finariTSa instead of finariTRa, they do not have the time to close the mouth
madagasikara: same problem: american people do not pronounce it madagasikara= all syllables must be pronounced, instead they say car, with a long a at the end of the word, so they tend to speak quickly to end with a long vowel = madagasCAR
tahionao : TAhionao: always the problem of a long a= it is false if it sounds like o, like in caught
you'd better say e like in set =tehionao
T in tokoa: t is not at the tip of lips and the teeth, it is on the back of the front teeth added with u round like in suit, so you should have the two lips rounded like for a whistle, or a spitting, k is not pronounced alone like in ck, it is with u already so you keep the lips and cough a little bit, that makes ko and not t-ck
same problem with ity= T is not so high, you pronounce it iTTTi, the i at the end of the word closes the word and the sound is long on y not on t = so it is itY
In all, to speak malagasy, you must speak at the tip of your tongue and teeth, and the palate, always high, never long and back,
