Lingotion’s Thespeon Engine replicates a REAL ACTOR’s voice, facial expressions and emotions with unique dialects & quirks turning your characters into lifelike expressive individuals, 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 character or the 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 characters 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, character and voice-over development has prioritized perfect audio and animation—at the cost of truly interactive experiences. Character 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 character interaction in games.
"With a vast range of emotions, styles, and nonverbal sounds—plus customizable dialects and language flexibility—your characters 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 AI-acting unviable due to its high operational expenses. The only sustainable way to run real-time AI-acting 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’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 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 create unlimited real-time character interactions at no additional cost – preserving the industry’s near-100% gross margin.
Retain near-100% gross margin on your game

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 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 ensure legal compliance by having direct agreements with every actor, securing full legal rights to use their data for AI. As legal uncertainty around AI training data grows, our agreements guarantee lawful use, 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
