I wanted to make an AI talk to me like a real human.
Not a chatbot that waits for you to finish speaking. Not a voice note exchange. I wanted an AI that could listen while I spoke, interrupt naturally, and respond instantly — like a personal assistant or customer-care agent. Something that didn’t just reply, but could actually do things — send emails, check dashboards, automate tasks.
So I started small. I used a basic text model with Kokui for speech-to-text. The first time it responded, it felt magical — until it started ignoring me mid-sentence, replying late, or not speaking at all. Latency was awful. It wasn’t a conversation; it was waiting for a robot to remember it existed.
I upgraded to DeepGram, tuned the audio, and still, it felt disconnected. I wanted real-time. I wanted the AI to exist in time with me, not after me.
So I went deep into research. GitHub, StackOverflow, documentation black holes, even different AI platforms — but nothing gave me the real-time link I needed.
Then I found one line buried in a doc:
“OpenAI uses LiveKit for real-time voice.”
That changed everything.
LiveKit works like Zoom — a room where participants join and talk.
I built my agent to join a LiveKit room, then I joined as well.
And for the first time, I wasn’t sending messages to a server — I was talking to an AI inside the same space.
The first test stunned me.
Latency dropped to about 50ms.
The AI listened while I spoke, and responded instantly.
For the first time, it felt alive.
Then came a strange bug.
The AI joined once, but couldn’t reconnect after leaving. I rewrote code, regenerated tokens, nothing worked — until I realized LiveKit doesn’t let you rejoin a room with the same token.
I changed the room name and boom — it worked flawlessly.
Now it runs inside LiveKit Sandbox, talking and listening in real-time.
It can send emails, check dashboards, handle automation — all with almost zero delay.
I started out trying to make a talking AI.
What I built feels more like a digital employee — one that works, listens, and speaks in real time.
And the best part?
It doesn’t feel like the future anymore.
It feels like now.
