A Push-to-Talk Key for Coding Agents

The Voice Pad ($79) is a compact mechanical keypad supplied with a microphone, and three of its controls are the whole idea: a microphone key, a tick and a cross, next to a single knob. The microphone key is the push-to-talk. You hold it while you speak, let go, and the words land in whatever window has focus.

What does a push-to-talk key actually send?

A keystroke. That is the honest answer and it is also the useful one. Our hardware behaves like a second keyboard: the microphone key sends whatever key or combination you have mapped to it, and something else in the chain decides that this key means start listening. That something else is your operating system's dictation, your editor's voice input, or a short script you run yourself. The key performs no recognition of its own, and it has no idea that Claude Code or Codex CLI is the thing on the other side.

Which is exactly why push-to-talk works the same across every terminal agent. If a tool accepts typed text, it accepts dictated text, because by the time the words reach it they are indistinguishable from typing.

Hold to talk, or press once to start and again to stop?

Both exist, and the difference matters more than people expect. Hold-to-talk keeps the microphone open exactly as long as your finger is down, so a stray sentence to someone walking past never reaches the prompt. Toggle is one press to start and one to stop, which is kinder to your hand on a long dictation and merciless if you forget the second press.

Which one you get is decided by the software you point the key at, not by the key. In practice, people who dictate a paragraph at a time settle on toggle, and people who dictate a sentence at a time settle on hold.

Where should the key live: desk, hand or floor?

Three shapes, one job. The Voice Pad keeps the key on the desk under your left hand, next to the tick and cross you tend to press straight afterwards. The Vibe Pad ($59) is the smaller version of the same idea: three mechanical keys and a separate clip-on microphone. The Whisper Key ($87.90) puts the key on the microphone instead, a clear polycarbonate handheld you hold close to your mouth and speak into quietly, which is the one to reach for in a room full of other people.

The floor is the fourth option and the only genuinely hands-free one. Pedal Three ($69) gives you three pedals, and a common split is accept, reject and push-to-talk, so the microphone opens while both hands stay on the keyboard. That is the closest this catalogue gets to talking and typing at the same time.

Do I need a dedicated key for this at all?

No. Your keyboard already has keys, and if you have a spare modifier or a function key that nothing is using, you can gate dictation with it today for nothing. A dedicated key earns its place for two reasons only. It sits somewhere your hand finds without looking, and it cannot collide with a shortcut inside the editor you are dictating into. If neither of those is a problem you actually have, keep your money and use the key you already own.

If you are weighing up voice hardware in general rather than the key that gates it, our note on using voice input with terminal coding agents covers the rest.
