A supposed former Rockstar Games employee revealed on Reddit that the sound system in GTA 6 (Grand Theft Auto VI) is far more advanced than anyone imagined.

According to him, the inhabitants of Grand Theft Auto VI won’t repeat stock phrases; they’ll have hundreds of thousands of recorded lines to react to almost everything the player does on the Leonida map.

Leak details voice system in GTA 6

Forget the repetitive dialogue from GTA 5. According to the leak, Rockstar Games has created a system where characters change what they say based on various real-world factors:
- Weather affects mood: GTA 6 NPCs may sound noticeably more irritated if it’s unbearably hot or raining heavily.
- Memory of crimes: They will react differently if they witness a crime right in front of them or if they only hear about what happened through the news or rumors.
- Conversations that evolve: Two characters might start arguing over a parking spot, and the conversation could naturally escalate into a physical fight, with dialogue that reflects this escalation.
- No Repetitions: The test conducted by the sound team ensured that, even when standing next to an NPC for 20 minutes, they almost never repeated the same line, seeking deep variations within the system.
How does this supposed dialogue system in GTA 6 work?

The big secret revealed by the leak isn’t just the number of lines, but how the game “assembles” them in real time. The system operates through three main pillars: categorization, conditionals, and chaining.
Categorization by "Tags"
Instead of a giant folder with audio files, each line of dialogue has several "labels." Imagine that a convenience store clerk NPC has a recorded line of dialogue. The game doesn’t just see it as "clerk’s line." It reads it like this:
- Who: Convenience store clerk.
- State: Recognizes the player (you’ve robbed him before).
- Emotion: Moderate panic.
- Environment: Night and Raining.
The game only plays this specific audio clip if all these conditions are met during your gameplay. If it’s sunny, the system discards this audio clip and searches for the “Sunny” tag.
The modular system
The leak mentions that the dialogues are "modular." This means that an interaction can be assembled in parts.
- Part A (Greeting): "Hey, it's you again…"
- Part B (Reaction to the crime): "…I heard you caused a ruckus at the port…"
- Part C (Farewell): "…don’t get me in trouble today."
Each part of this is a separate file. The game combines the three parts based on what you did in past missions. This creates the illusion that the NPC is a real person who "knows" about your life.
Conversation Chaining
This is what makes the NPCs in GTA 6 talk to each other. The system works like an "If/Then" flowchart:
- NPC A starts: "Have you seen the price of gas?" (Tag: Economy_Complaint)
- NPC B responds: If NPC B is "Rich," they ignore it. If NPC B is "Poor," they agree and escalate the conversation.
- Result: The game pulls a sequence of IDs that link the two characters’ lines, creating a discussion that can last for minutes without repeating anything.
Dialogue Decay (The End of Looping)
To prevent the world from feeling artificial, there is "Decay." If you stand still listening to an NPC, the system marks lines that have already been used as "exhausted." To avoid repetition, the game is programmed to seek out increasingly rare and specific variations. That’s why the tester didn’t hear any repetitions even after 20 minutes of observation.
The Controversy Between SAG-AFTRA Voice Actors and GTA 6

The leak also details tensions between the gaming industry and the actors’ union (SAG-AFTRA). The source explains that this “is not a normal voice acting job,” but rather the construction of a massive database.
Check out the video below from our partner SanInPlay from 2024 that discusses this very rumor about GTA 6:
Actors are asked to record the same phrase in dozens of different tones (neutral, panicked, whispering, wounded), intensities, and demographic variations.
In short, this colossal volume of work and concerns about the use of these recordings to train generative AIs are said to have fueled the recent walkouts in the industry.
