AI Voice Agents
Hire a freelance AI voice agent developer
I build AI voice agents that pick up the phone, hold natural conversations, answer questions and book appointments, so you never miss a call or a customer again.
My voice agents use a low-latency speech-to-text, LLM and text-to-speech pipeline with natural turn-taking and interruption handling, and can look things up live during the call.

FAQ
AI Voice Agents: common questions
Does an AI voice agent sound natural?
Yes. Modern text-to-speech voices sound very human, and my agents handle natural turn-taking and being interrupted, with low response latency.
Can it book appointments directly?
Yes. The agent can check availability and create bookings in your calendar or booking system during the call.
What happens if the caller needs a human?
The agent can take a message, send a summary to your team or transfer the call, depending on your setup.
Will I get a record of each call?
Yes. Calls can be transcribed and summarised automatically, so you can review what was discussed.
