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 creates local dictated text or a structured brief you can review 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.

IraVoice keeps its speech recognition and supported formatting on the Mac, with the initial model download and paid license verification disclosed separately.

4. Use Voice-to-Spec for a reviewable handoff

Hold Globe in IraVoice and describe the goal, constraints, and acceptance criteria. Focused-app delivery inserts the resulting Markdown for review.

If you explicitly select Codex as the Prompt destination, IraVoice can open a visible interactive Codex session in the detected repository and submit a guard-accepted specification. It does not use unattended or permission-bypass flags, and it fails closed to the clipboard when the CLI, repository, focus, trust, sign-in, or guard state is not safe. 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 turns speech into Markdown and can optionally launch a visible Codex Terminal session to submit a guard-accepted specification; Codex then runs under its normal permission model.

Why create a brief instead of speaking directly?

A visible brief gives you a review step and a reusable artifact. Direct Voice is better when you want a live, conversational interaction with Codex.
