How a Vintage Phone Became a Cloud Voice Agent (Full Transcript)

[00:00:00] Speaker 1: This is how I built a voice agent into this vintage phone powered by Assembly AI's Voice Agent API. So the first thing I did was I opened up the vintage phone itself. I got it off of Facebook Marketplace and didn't know what to expect. I also picked up this ESP32 kit. It's like a tiny $10 computer. And here's the trick, it doesn't need to run any AI at all. Assembly AI's Voice Agent API is just one web socket. So audio goes in and the agent's voice comes back. So the next order of business was to figure out which of these wires carry audio. So it turns out red and green are the mic and yellow and black are the earpiece. So that's what will wire into the ESP32. So I'm labeling each wire as I free it because once I start soldering I don't want to mix these up. This was my very first time soldering by the way and honestly it was way less scary than I thought. So wires out and the labels are on and we have everything connected to the ESP32. We plug in USB-C and we should be good to go. Cloud Code Fable had my back all the way. All of the code was written by agents and I've open-sourced the code for you in the GitHub link in the description.

[00:01:10] Speaker 2: All right so here it is. Let's give it a try. Yeah, what's the weather normally like in New York in July?

[00:01:27] Speaker 1: It is usually a bit of a mixed bag. You might get sunny skies or a sun drizzle, especially if you are visiting in the spring. Are you planning a trip to the Big Apple?

[00:01:38] Speaker 2: Sure am, see ya, bye.

[00:01:41] Speaker 1: Yay. I had way too much fun with this and the voice agent part was genuinely the easiest step. So over to you. What do you think this phone should do next? Let me know in the comments. Bye.
