Maanca: Sorry for late answer, but except Dan Castellanetta who recorded Homer's line for the initial release, as well maybe as a few other of his characters (Grampa, Squeaky-Voice Teen...), and possibly Yeardley Smith, the voice actors never provided voices for the game.

Almost all the characters from levels 1-22 only make "simple, quiet grunts" taken from the episodes.

Since Level 23, they use voice clips from The Simpsons Game, which is why they have full, long lines. Since Hugo wasn't on the Simpsons Game, they did like the characters from the early stage of the game.
