Challenge
Mobile conversation needed low latency while chaining STT, LLM, and TTS without freezing the UI.
How we did it
Streamed audio through STT, routed text to an LLM service, then returned TTS audio optimized for Android playback.
Outcome
Users got a responsive conversational avatar experience suitable for production demos and apps.
