Not sure what you mean. All the lines are said by Mido. But of course his line "What? You're right, I don't have my equipment ready, but..." means that Link said something to Mido. Of course Link talks, they just almost never show it in the games, since Link is supposed to be mostly silent.
There are some parts in the game though where I'm not sure whether it's Navi or Link talking due to some lack of blue text (explicitly indicating Navi). But I honestly think Link's only written line in the game is him telling Zelda his name.
