Do gta online missions include voice acting?

All GTA Online missions include fully voiced dialogue. The main protagonists—Michael, Franklin, and Trevor—are voiced by the same actors as in the single‑player campaign, and every non‑player character has a voice actor as well. Mission objectives, cutscenes, and in‑game text are accompanied by spoken lines, so players hear the same actors deliver the script that accompanies the gameplay. The voice work also extends to the various gang members, mission crew, and background characters that populate the missions’ environments. Consequently, the audio experience is consistent with the single‑player game and provides a fully immersive narrative.
