Spatius

Spatius gives voice AI agents a talking face by streaming small motion controls to an avatar that renders on the user's device instead of in the cloud. Developers use its Web, iOS and Android SDKs to add avatars to apps, kiosks and support agents at low cost per hour.

You keep your own agent and voice stack; Spatius turns the audio into expression and timing data, and the renderer draws the face locally. Because no continuous video stream is sent, bandwidth and cloud costs stay low, and avatars can be interrupted mid-sentence.

It integrates with LiveKit, supports more than 100 languages and lets paid plans create custom avatars each month. Plans are sold by credits, concurrent sessions and maximum session length, and an Enterprise tier offers region choice and an availability commitment.
