Do gta online missions include voice dialogue?

Grand Theft Auto V is described as an action‑adventure game developed by Rockstar North and published by Rockstar Games. The Wikipedia entry outlines the single‑player story, the open‑world setting of San Andreas, and the main protagonists, but it does not mention any details about voice dialogue in the game or its online component. Because the source does not contain information about scripted voice lines or dialogue for GTA Online missions, we cannot confirm that such dialogue exists. A definitive answer would require additional sources that address the online missions specifically.
