Character Engine is an Authoring Tool and an SDK, which can be installed to easily to create digital characters, for games and beyond.
Create distinctive personalities who will show emotion and respond dynamically to the player – yet still hit the key beats of your story.
Players and users communicate naturally to characters through speech or text – and they understand and respond with the personality
and emotion of real people.
Endow your characters with dialogue that flows freely through speech and text. Our natural language processors understand players in context, enabling your characters to select the best response from their scripted lines or to auto-generate dialogue based on knowledge models of the world you give them.
Your creative team can define personality & emotional traits in the Character Engine. Each character is given its own voice, script lines and an understanding of its world.
Players or users speak or type; Spirit AI recognises entities mentioned in the speech as well as emotional tone, question type and other factors.
If the player has asked a question represented in the Character Engine’s data, it formulates a response dynamically based on that information – even answering comparative questions.
The Character Engine also considers social context and what should come next in the story – whether that’s responding to a greeting or giving a gameplay hint.
Once the Character Engine has identified all the information it needs, it assembles a response that reflects that information, as well as its own personality traits, emotional context and game state.
Spoken output is rendered in the voice of the character.
Studies by the Spirit team have shown that immersive interfaces can lead players to think of virtual characters more like real people. VR can be so immersive that players expect characters to behave naturalistically, and it breaks immersion when they don’t.
Character Engine empowers you to create truly meaningful story spaces & characters, in VR or otherwise. We free your creative voice – and your budget – enabling you to tell the stories you’ve always wanted to tell.
