Translation:Well done Anna! You are a really good singer.
Nothing has been changed. Like pieni_chilipalko says in a comment above, olet tosi is pronounced as one word, olettosi. This means that instead of two T's, you get one long one, like in the name Matti. Since the T is unaspirated, it's often hard for speakers of Germanic languages to spot it. You can find more info about aspiration and long consonant sounds in the Tips for Good Luck!. :)
