Voice agent

From an idea to an agent you can talk to, in one hour.

We built a working voice agent on AssemblyAI’s Voice Agent API, which handles listening, turn-taking, reasoning and the spoken reply in one real-time stream. I shaped the concept and built the agent, using AssemblyAI’s prompt tooling and Lovable.

Voice AI integration

Built on AssemblyAI’s Voice Agent API: speech recognition, turn detection, LLM reasoning and voice in one stream.

Prompt and conversation design

Wrote and tuned the agent’s prompt with AssemblyAI’s prompt tooling, testing it by talking to it.

Working to a brief, fast

Shaped a concept and cut it down to what one hour could deliver.

Rapid prototyping

Lovable for the interface, so the hour went on how the agent behaves.

Problem, build, result

1Problem

One hour, live, to go from nothing to an agent that answers out loud.

2What I built

A voice loop on AssemblyAI’s Voice Agent API, a prompt written for the ear, and a Lovable interface around it.

3Result

A working voice agent you could talk to by the end of the hour.

Listen

The Voice Agent API turns live speech into text and detects when you have finished.
