I Built a Custom AI Voice Mode (And It Roasted My Hardware)

Lorenzo Colombani

A spoken interface for a command-line AI coding tool: a foot pedal in, spoken replies out — until the pedal lost to the mouse wheel.

Behind the experience

The interface gets a voice. The hardware gets a verdict.

This demonstration turns a command-line AI coding tool into a spoken exchange. A foot pedal starts the interaction and the assistant answers aloud.

The public description follows the experiment to a change in input: the pedal gives way to the mouse wheel. It is a practical look at a voice workflow and the physical control used to reach it.

Project notes

The interface gets a voice. The hardware gets a verdict.

Input and response

The demonstration combines a physical trigger with speech in both directions, moving part of a coding conversation away from the keyboard.

The control changes

The foot pedal and mouse wheel are both part of the published story. Their contrast makes the choice of input hardware part of the interface experiment.
