Codex

Codex has live Voice. IraVoice is a different kind of input.

Current ChatGPT desktop builds can use Voice with Codex to discuss, start, and coordinate tasks. IraVoice does not compete as a live agent conversation. It types your words into the Codex prompt, with your project’s code names spelled the way the code spells them, so you can review the text before any agent acts.

Source-reviewed

1. Use built-in Voice for a live Codex conversation

Open the ChatGPT desktop app on macOS or Windows, select Codex, then select the Voice control. Allow microphone access when prompted and describe the task or question.

OpenAI documents Voice in Codex as a live interface that can use the tools and permissions available to Codex. That makes it the natural choice for back-and-forth coordination.

2. Treat live Voice and dictation as different interfaces

Live Voice is conversational: you can speak, interrupt, ask questions, and coordinate an active task. Dictation is text-first: speech becomes editable text before you decide what to send.

Choose based on the control point you want. A live conversation is fast; a visible brief is easier to inspect, archive, compare, or reuse across agents.

3. Check the current Voice data controls

OpenAI’s Voice documentation describes retention and model-improvement controls for audio, video, and transcripts. These rules can depend on the voice mode, plan, and workspace, so use the current OpenAI help article rather than a third-party summary.

On IraVoice Local, speech recognition runs on your computer and no audio or text leaves it. The one-time model download and the weekly license check-in are disclosed separately and never carry your words.

4. Use IraVoice for a reviewable, correctly spelled prompt

Click into the Codex prompt in a terminal or the app, hold Right Command on a Mac or Right Ctrl on Windows (Ctrl+Space on Linux), describe the change, and release. IraVoice finds the Git project Codex is working in and spells its code names: “use effect” becomes useEffect and “pipeline dot swift” becomes Pipeline.swift.

IraVoice reads only names, never source text, skips secrets and dependency folders, and sends nothing off the computer. It types the prompt and does not press Enter by default, so you review the text before Codex acts. Codex still owns execution and permissions.

Questions

What readers usually ask next.

Can I use Voice with Codex?

Yes, for eligible accounts in the ChatGPT desktop app on macOS and Windows. OpenAI says Voice can use the tools and permissions available to Codex.

Is IraVoice a live voice mode for Codex?

No. IraVoice does not provide a spoken Codex response or a live conversation. It types your words into the prompt, with code names spelled from your project, and you decide when to send; Codex then runs under its normal permission model.

Why dictate text instead of speaking directly?

Typed text gives you a review step before the agent acts and keeps file and function names exact. Direct Voice is better when you want a live, conversational interaction with Codex.
