Challenge
Most voice assistants sound functional but emotionally flat. High latency, unnatural pacing, and poor prosody break immersion and make conversations feel artificial. The challenge was to design a voice agent that could respond quickly, handle conversational nuance, and express emotion through subtle vocal cues—while remaining technically lightweight and reliable.
Goal
Create a voice AI that: Responds with near real-time latency Uses pauses, tone shifts, and pacing naturally Expresses emotion without exaggeration Feels conversational rather than transactional The emphasis was realism, flow, and emotional presence.
Result
Achieved consistently low conversational latency Noticeably more natural turn-taking compared to baseline agents Improved perceived emotional realism in user tests Demonstrated the impact of prosody and timing on trust Mia shows that expressive voice design can dramatically change how AI conversations are experienced.
