Which Mario Party game was the first to feature full voice acting for characters?

Mario Party 4 was the first Mario Party game to feature full voice acting for its characters. Released for the Nintendo GameCube in 2002, it moved the series into a more expressive presentation with recorded character performances and spoken reactions alongside its board-game action.

The game’s voice cast included Charles Martinet as Mario, Luigi, Wario, and Waluigi; Jen Taylor as Peach, Daisy, and Toad; and Kazumi Totaka as Yoshi. Mario Party 4 was also the first entry in the series released for the GameCube, and its characters appeared in fully 3D-rendered boards rather than the more limited presentation of the Nintendo 64 games.

Earlier Mario Party titles were not completely silent: they used short voice clips, vocal sounds, announcer lines, and recycled character audio. That is why “full voice acting” can be confused with the presence of any character voices at all. The distinction is that Mario Party 4 established the more substantial character-voice presentation associated with later entries.
