How to build your first AI voice agent in 15 minutes (even if you’ve never touched voice tech)
Cartesia just made Managed Agents generally available. Here’s the beginner path:
Step 1: Write what your agent should do, in plain language (“You’re the front desk for a dental clinic…”)
Step 2: Pick an LLM and a voice (calm concierge, friendly, formal)
Step 3: Upload your FAQs or docs so it answers from your info
Step 4: Connect tools (calendar, order lookup)
Step 5: Get a phone number and call it
That’s it. Cartesia handles the hard parts: speech recognition, knowing when you’ve stopped talking, interruptions, the voice, and the phone line.
