Audio-level motion
The app supplies amplitude in an agreed range and audio lifecycle events. This does not identify individual speech sounds.
RIVE ANIMATOR · Speech motion that matches your available voice data.
Rive Lip-Sync Animation
Choose the speech approach around your application. Audio-level mouth motion uses normalized amplitude; viseme lip sync uses timed speech events mapped to reusable mouth shapes.
What we prepare
Timed visemes
The app supplies TTS or phoneme timings, a viseme mapping and playback clock.
Reliable rest pose
Reset the mouth when speech stops, fails or is cancelled; test interruption and missing callbacks.

How is the project priced?
Mascot animation starts at $250 with client-supplied artwork: one character, idle plus one extra state, basic State Machine setup and the .riv source file. Custom design has a $650 animation-package minimum with one design included. Extra characters add $250 each; extra states add $100 per state per character. Viseme setup adds $350 for one talking character after the design minimum. Additional designs and talking characters are quoted separately.
What should I send?
