Arc Raiders developer Embark has defended its use of generative AI for voice lines, with Chief Creative Officer Stefan Strandberg stating that the technology was necessary to avoid burdening voice actors. The studio previously faced criticism for using AI-generated voices, which were created by feeding real actors' performances into machines.
In a video discussing the game's audio design, Strandberg asserted that Embark is "not in the industry of replacing actors." He referenced the game's reliance on AI for incidental dialogue, such as pings, quest information, and mission briefings. Audio director Bence Pajor explained that the AI approach was intended to circumvent the logistical challenges of coordinating actors' schedules, particularly when new dialogue is needed for features that evolve. Pajor suggested that recording every possible variation of certain lines would be impractical and potentially overwhelming for actors, stating, "The actors would just go crazy if they had to read all of that."
This justification is met with skepticism, drawing comparisons to games like Disco Elysium and Baldur's Gate 3, which feature extensive voice acting without relying on generative AI. The live-service shooter Apex Legends was also cited as an example of a game that has consistently added and updated voice lines through traditional recording methods over several years.
Embark CEO Patrick Söderlund had previously indicated that lines originally generated by AI were being replaced with newly recorded performances. This shift was reportedly enabled by the financial success of Arc Raiders. The studio's previous title, The Finals, also encountered similar criticism regarding its use of AI-generated voices.
Voice actors Jo Rideout (Shani) and Diana Gardner (Celeste) shared their perspectives on the hybrid model. Gardner noted that the arrangement allowed for flexibility, enabling her to accept other projects when only a small amount of voice work was required. She found the contract fair, but expressed a degree of detachment from the final product, stating, "I was like, 'Can I take ownership for the performance?' This is hours of work that I've put in, but can I take ownership for the final product? No."
Strandberg reiterated his stance, suggesting that AI could potentially create "more space" for actors. However, the decision to initially employ AI is seen by some as a cost-saving measure, allowing the game to be developed more quickly. The ongoing replacement of AI lines with human performances indicates a willingness to invest in traditional voice acting, but the initial choice raises questions about the studio's long-term approach to talent and cost management.
