Real-time voice companion for conversation practice
A speech-to-speech companion where learners talk with characters that have their own persona, voice, and animated face — the conversational brain we bring to educational robots.
Challenge
Deliver natural, low-latency voice conversations with expressive, lip-synced avatars across iOS, Android, and web — engaging enough that learners keep practicing.
Solution
We built a multimodal pipeline — speech recognition, in-character reasoning with guardrails, high-quality speech synthesis, and lip-synced video — behind a mobile-first experience for creating and talking with companions.
Results
- Cross-platform release from a single codebase
- Persona-consistent conversations with custom voices
- Same pipeline now powering robot conversation and tutoring
