Ladies and gentlemen… [clear throat] the moment we've all been waiting for has finally arrived!
After months of relentless preparation, [gasp] late nights, and endless dedication, today is the big day.
I'll admit… sleep wasn't exactly easy last night. [chuckle] The excitement was just too much to handle.
[cough]Along the way, we faced challenges that tested our patience and determination.
Some obstacles honestly felt impossible at the time… [groan] like there was no way through.
But [sniff] we refused to quit.
[shush] And now… here we are, standing on the edge of something truly incredible.

Flexibility or timing. Never both, until now.
Most voice agents run one channel at a time. Full Duplex keeps both channels open for the whole session, so the agent can be interrupted, backchannel and reply without dead air.
Flexible, but waits its turn.
Hear, think, then speak, one channel at a time.
Fast, but fixed at build time.
Natural timing, with the persona baked in when the model is trained.
Both, in one live session.
Both channels stay open the whole call, and the voice and role remain prompts.
Give your agent a voice, on a model that belongs to you.
