Sony Explores AI-Powered PlayStation Character Interactions

Sony is pushing the boundaries of gaming technology by developing AI-powered PlayStation character interactions, as evident from a recently leaked internal video. This innovation showcases an AI-driven version of Aloy, the protagonist from the popular Horizon game series, engaging in conversations with players.

The Leaked Prototype

A report by The Verge reveals that an anonymous source shared a video of an internal Sony presentation featuring an AI-powered Aloy from Horizon Forbidden West. The video, which has since been removed due to copyright claims, was narrated by Sharwin Raghoebardajal, a director of software engineering at Sony Interactive Entertainment. In the demonstration, Aloy responds to player questions with artificially generated animations, dialogue, and voice. This prototype was developed in collaboration with Guerrilla Games, the studio behind the Horizon series, as an internal proof of concept.

Technology Behind the AI Character

The AI-powered Aloy prototype leverages a combination of cutting-edge technologies:

• OpenAI’s Whisper for speech-to-text conversion
• GPT-4 and Llama 3 for conversation and decision-making
• Sony’s proprietary Emotional Voice Synthesis (EVS) for speech generation
• Sony’s Mockingbird technology for facial animation

This blend of technologies enables the AI character to engage in more dynamic and responsive interactions with players, enhancing the overall gaming experience.

Potential Applications and Concerns

While the demonstration is impressive, it raises questions about the practical applications of this technology in gaming. The Horizon series is known for its strong narrative and well-written characters, and it’s unclear how AI-driven conversations would enhance the player experience. Here are some potential applications and concerns:

Interactive Storytelling

• The AI model could expand on prompts and fill in gaps with details from the game’s story, providing an interactive way for players to refresh on the narrative if they’ve missed out on certain parts.

Game Help Feature

• This technology could replace or work alongside the PS5 Game Help feature, offering more personalized and interactive assistance to players.

Events and Exhibits

• It could also be used for events or exhibits, providing a unique and engaging experience for gamers.

Voice Acting Concerns

• The use of AI in character voicing raises concerns within the voice acting community. Voice actors, including those involved in the Horizon series, might worry about their roles being replaced by AI-generated equivalents. This concern is reflected in the current SAG-AFTRA strike over protections against AI in voice acting.

Sony’s AI Strategy

This prototype represents a significant shift in Sony’s approach to AI in gaming. While competitors like Microsoft and NVIDIA are focusing on using AI for game ideation, prototyping, and animating game characters, Sony has primarily applied AI and machine learning to hardware improvements and frame generation techniques.

It’s important to note that this technology is still in the prototype stage, and there are no immediate plans to integrate it into commercial games. However, it demonstrates Sony’s interest in exploring how AI could reshape character interactions in future PlayStation titles.

As the gaming industry continues to evolve, the role of AI in enhancing player experiences remains a topic of both excitement and debate. Sony’s experiments with AI-powered characters like Aloy represent just one potential direction for the future of interactive entertainment.
