Voice In, Voice Out: A No-Code AI Agent Pipeline

What This Video Covers

A voice agent built entirely on the canvas and served by local engines. Speech goes in, Whisper transcribes it, a small local model (Llama 3.2) answers in two or three plain sentences, and Kokoro reads the answer back. The video installs the voice sample from Settings → Samples, after installing the two speech models from the registry.

It walks through each node — the audio input, the transcribe node and its error branch, the LLM's system prompt, the speak node — then records a question in the test panel, plays the spoken answer, and reads the run trace to see where the time goes: text-to-speech is the slowest step. It ends by showing that any of these models can be swapped, for another local model or a hosted API, without touching the agent.
