Imagine an NPC (Non-Player Character) or voice-over that dynamically manifests feelings based on game state in real-time. With a range of 50+ emotions, 8 styles, and 30+ nonverbal sounds it will change the way you interact with NPCs forever!
We secure the legal rights of AI training data and uphold actors’ rights of their craft through direct agreements with each performer for the explicit use of AI-acting. Lingotion exclusively uses lawfully acquired AI training data and provides full compliance documentation as proof for studios and third parties.
Lingotion’s Thespeon Engine replicates a REAL ACTOR’s voice, facial expressions and emotions with unique dialects & quirks turning your NPCs into lifelike expressive characters, controlled in real-time on the gaming device.
In the fast-paced world of game development, players expect deeper immersion, more interactive worlds, and characters that feel truly alive. But achieving that kind of realism is expensive, time-consuming, and technically demanding. Traditional acting is a costly inflexible process that requires constant re-recordings.
Imagine a world where your NPCs react naturally to player actions, delivering dialogue and facial expressions with emotion and depth—without reliance on cloud servers or recurring costs. With Lingotion’s AI-Acting technology, developers can create expressive NPCs that interact in real-time—no usage costs, no latency, and no internet dependency. And it works seamlessly on almost any gaming device—from budget smartphones to high-performance PCs.
Until now, NPC and voice-over development has prioritized perfect audio and animation—at the cost of truly interactive experiences. NPC interactions today feel more like passive, multi-choice movies than true player-driven experiences. Lingotion with its Thespeon AI-Acting Engine, running on any device with zero per-use license costs, is set to revolutionize NPC interaction in games.
"With a vast range of emotions, styles, and nonverbal sounds—plus customizable dialects and language flexibility—your NPCs can finally move beyond static, pre-recorded lines and feel truly alive."
"Thespeon is a tribute to the Greek Thespis—the first historically recorded actor from around 500 BC—and ‘Aeon,’ meaning eternity. With Thespeon, actors gain a new level of immortality, allowing gamers to interact with and experience their unique performances in entirely new ways, forever."
The Lingotion Thespeon AI-Acting Engine runs entirely offline on the player’s device, eliminating cloud costs and network dependencies.
The core business model of the video game industry requires a no-cloud solution due to its contribution margin structure.
Most video game revenue comes from one-time purchases or microtransactions—both of which offer high gross margins but cannot sustain significant ongoing usage costs. This makes cloud-based real-time generative AI unviable due to its high operational expenses. The only sustainable way to run real-time generative AI with a one-time fee model is to process everything locally on the player’s device—without the cloud.
Beyond cost efficiency, a 100% offline approach also ensures greater privacy, as no data ever leaves the player’s device.
Supports one-time fee models, including pay-to-own purchases, microtransactions, and freemium offers
Runs without an internet connection
Operates entirely on the player’s device with zero usage costs, eliminating recurring fees and dependence on costly external servers
Ensures greater privacy and security for players while reducing security risks and data exposure for studios

Lingotion Thespeon AI runs efficiently locally on the device, eliminating the need for cloud processing. It supports a wide range of gaming hardware, from older budget phones to high-end PCs. Designed for adaptability, it dynamically adjusts based on device capabilities, running on either CPU or GPU depending on available performance resources.
Just like graphics rendering adapts to hardware capabilities, Lingotion Thespeon AI offers multiple performance modes, ensuring low-latency, expressive dynamics on both low-end and high-performance devices—with output quality adjusting accordingly.
This adaptive approach lets developers design NPCs with an interaction-first philosophy. NPCs will always deliver consistent, realistic responses and interactions, regardless of hardware limitations. The only difference is the output quality that scales based on device performance—just like graphics rendering in modern 3D games.
Runs on-device, utilizing the player’s hardware
Low-latency, real-time generation across all devices—from low-end phones to high-end PCs
Supports both CPU and GPU execution
Adaptive performance scaling based on available resources
Lingotion’s pricing model is title-based—studios pay per game title, not per line or generated content.
The video game industry thrives on high gross margin business models, where per-use costs must remain low. Cloud-based or usage-based generative AI is simply too expensive for real-time interaction, making it unviable for most games.
With Lingotion’s on-device AI and flat pricing model, game developers can generate unlimited real-time NPC interactions at no additional cost—preserving the industry’s near-100% gross margin.
Retain near-100% gross margin on your game
Unlimited usage with zero per-line fees
Cost-effective pricing for both indie and AAA studios
At Lingotion, we believe in fair compensation and ethical rights for actors in the age of generative AI. Our actors retain royalty rights over all data they provide to Lingotion, and we operate as their agent—not just a license holder. This means that when Lingotion generates revenue, actors receive a direct revenue share.
We have direct agreements with every actor, ensuring full legal rights to use their data for AI. As legal uncertainty around AI training data grows, our agreements guarantee lawful use of training data, eliminating legal risks for studios and developers.
Lingotion provides comprehensive compliance documentation for all training data, proving its intellectual property legitimacy. This ensures that studios, distributors, publishers, and other third parties can verify the legal standing of our AI-actors.
Actors also have Ethics Level boundaries, allowing them to define how their likeness can be portrayed in games. However, a studio may use a character beyond these Ethics Levels with direct actor approval.
Legally compliant—zero legal risks
Transparent actor payment model ensuring fair compensation
Actors retain control over their identity and ability
Create expressive, game-state-driven character interactions—instantly.
Run everything on-device, even on mobile, with no cloud costs.
Give your NPCs unique personalities with ethical AI-acting.
