Lingotion Thespeon

Best for Licensed actor voices that run on the player's device

Can you ship it?

Paid plan needed Each published game needs a per-title character licence; prices only in the portal Source

Price

Free SDK and two starter characters to test; publishing needs a one-time licence fee per game title (or a smaller fee plus revenue share), priced in Lingotion's portal

Works with

Unity 6, Unreal; PC, macOS, iOS, Android, Quest

An on-device voice-acting engine: you license an AI clone of a real actor's performance (33 emotions per character) and the SDK speaks your lines at runtime on the player's CPU or GPU, with no cloud calls and no per-line fees. Actors get a royalty share and the training data is licensed. Two starter characters are free to test, but publishing a game with any character needs a licence per title, priced in Lingotion's portal rather than on the site, and a big expansion can count as a new title. English only for now; Unity 6 SDK on the Asset Store, Unreal SDK too.
