Lingotion Thespeon Acting Engine

Lingotion Thespeon is an on-device TTS acting engine designed to generate real-time character acting and voiceovers. It introduces a new era of game design, where player characters, NPCs and voiceovers act and react dynamically based on the game state—eliminating the need for prerecorded audio files and animations.

Lingotion Thespeon, named after the ancient Greek actor Thespis, focuses on generating acting. While real-time, game-state-driven script dialogue can be procedurally generated – offering near-infinite interactive possibilities – true immersion requires expressive acting.
