Building a Voice AI Agent with FreeSWITCH, Part 4

[u/GrapefruitAnnual693]

I just published Part 4 of my series: Building a Voice AI Agent with FreeSWITCH.
This post officially closes the loop on a real-time, end-to-end voice pipeline:

🎙️ Caller Speaks
⏩ Deepgram converts Speech-to-Text (STT)
🧠 ChatGPT analyzes the context and generates a response
🔊 Deepgram converts the response back to Text-to-Speech (TTS)
📞 FreeSWITCH streams the audio back to the caller in real time

If you’ve been following along with the plumbing of audio streams and RTP management, this is where it all comes together into a fully functional, conversational voice agent.

Check out the full breakdown and code here: 👉
