Reduce overlap
Live is designed primarily for one-on-one conversation and may respond to people talking to each other.
Voice troubleshooting
Most GPT-Live problems fall into four groups: rollout availability, the selected Voice mode, microphone or network conditions, and Live reacting to pauses or other speakers. Start with the smallest check that matches the symptom.
Last verified:
Install the latest iOS or Android app, or refresh ChatGPT.com in a supported current browser.
Look for Live, Advanced, and Standard. The Voice icon alone does not prove which mode is selected.
Availability depends on plan, region, workspace, and app version, and rollout can be gradual.
If Live is unavailable, continue with Advanced or Standard Voice instead of repeatedly reinstalling.
Use the current macOS or Windows desktop app, open a new empty Codex task, and start Voice before the first message. Check eligible plan and workspace settings, microphone permission, API-key login, and whether another Voice conversation is active.
Follow the Codex voice checklist| Symptom | Likely cause | Try this |
|---|---|---|
| ChatGPT interrupts too early | Long pauses, background sound, or another speaker | Ask it to wait until you say to respond; use headphones and a quieter room |
| It stops speaking | Noise, network conditions, microphone behavior, or a reached limit | Check connection and account notice; raise device volume and reduce competing audio |
| Microphone does not work | OS, browser, or app permission | Allow microphone access for ChatGPT and confirm the intended input device |
| Wrong mode opens | Voice preference or unavailable option | Select Live explicitly under Settings → Voice |
| Conversation suddenly ends | Usage, two-hour session, context, force-close, or background rule | Read the notice, continue in text, or start a new Voice session |
| Transcript differs | Overlap, noise, fast speech, or transcript summarization | Treat Voice transcripts as review aids, not verbatim records |
Live is designed primarily for one-on-one conversation and may respond to people talking to each other.
On iPhone, open Control Center during Voice, select Mic Mode, and enable Voice Isolation when available.
Begin with “Wait until I ask you to respond.” Sounds and long pauses can still trigger a reply, but the instruction helps.
Live responses appear as text while spoken, and a transcript is added after the conversation. OpenAI warns that it may not exactly match either speaker, especially with overlap, noise, or rapid conversation.
For an editable record of one recording, use ChatGPT Dictation instead. For important decisions, verify the original information rather than treating a Voice transcript as authoritative evidence.
Live is rolling out gradually and depends on plan, region, workspace, and app version. Update ChatGPT and use an available mode while you wait.
It is primarily designed for one-on-one conversation and can mistake background or nearby speech for a prompt.
Possible causes include a usage limit, the two-hour per-conversation maximum, a long conversation's context limit, a forced app close, or background-session conditions.
