As of June 2026 there is only one voice in ChatGPT. OpenAI retired the old “Standard” voice (the speech-to-text → text → text-to-speech pipeline) in late 2025 and now ships a single end-to-end realtime voice, branded simply ChatGPT Voice (formerly “Advanced Voice”). It runs on GPT-5.5 over a WebRTC connection, so almost every “voice not working” report comes down to one of four things: microphone permission, the wrong input device, a stale app build, or you’re on the macOS app where voice was retired.
You start it with the waveform icon at the bottom-right of the message box (in the app or on chatgpt.com). Voice is now included on every plan — Free gets it with usage limits (measured in hours), Plus is effectively unlimited.
Fastest fix
- Grant the microphone permission at the OS level (not just in ChatGPT), then force-quit and reopen the app or reload the tab.
- Switch the system input back to the built-in mic if Bluetooth headphones are connected.
- On a Mac? The desktop app’s voice was retired on January 15, 2026 — use
chatgpt.comin Safari or Chrome instead.
If voice still won’t start after that, work through the table below.
Symptoms
- Tap the waveform icon and nothing happens
- “Connecting…” spins, then
Connection failed, tap to retry - The blue orb appears, but the transcript never updates and the model never speaks
- Voice works in the app but not the web (or vice versa)
- The waveform button is missing from the input bar entirely
- Voice breaks the moment you connect Bluetooth headphones
- Voice cuts out, stutters, or drops mid-conversation
Which bucket are you in?
| What you see | Most likely cause | Jump to |
|---|---|---|
| Tap mic, nothing happens, no permission prompt | OS mic permission revoked | Step 1 |
| You hear yourself but the model never responds | Wrong input device (Bluetooth/SCO) | Step 2 |
| Waveform button missing on Mac desktop app | macOS app voice retired Jan 15 2026 | Step 3 |
| Waveform button missing everywhere, even on web | Stale build, or signed out of a synced state | Step 4 |
| Works in app, fails on web (or vice versa) | Browser site permission | Step 5 |
Connection failed, tap to retry / stutter | Network blocks WebRTC (VPN, firewall) | Step 6 |
| Hit a usage wall on Free | Free voice has an hours-per-period cap | FAQ |
Common causes
In rough order of frequency:
1. OS microphone permission revoked or never granted
The first-time iOS / macOS permission prompt only fires once. If you tapped “Don’t Allow” then, or later turned it off in Settings, tapping the waveform button silently fails — the app will not re-prompt on its own.
How to verify:
- iOS / iPadOS: Settings → Privacy & Security → Microphone → check the ChatGPT toggle is ON
- macOS (browser): System Settings → Privacy & Security → Microphone → confirm Safari / Chrome is allowed
- Android: Settings → Apps → ChatGPT → Permissions → Microphone → Allow
- Windows: Settings → Privacy & security → Microphone → confirm both “Microphone access” and the ChatGPT app / browser are On
2. Bluetooth headphones or wrong input device
When you connect Bluetooth headphones, the OS often switches the default input to them. If the headset falls back to an old hands-free profile (mono / SCO), the audio path can be too poor for realtime voice and the model effectively never hears you. AirPods and car kits are the usual culprits.
How to verify: switch the system input back to the built-in mic and test. macOS menu bar → Sound → Input → pick “MacBook Pro Microphone”, not the headphones.
3. You’re on the macOS desktop app (voice retired)
OpenAI retired voice in the ChatGPT macOS desktop app on January 15, 2026 to consolidate on a single realtime stack. Voice is unaffected on chatgpt.com, iOS, Android, and the Windows app — only the native Mac app lost it. If your waveform button vanished specifically on the Mac app after that date, this is why.
How to verify: open chatgpt.com in Safari or Chrome on the same Mac. If the waveform button is there and works, the desktop app is the problem, not your account.
4. App build too old / waveform button missing
Older builds lack the current voice handshake, so the button may be missing or “Connecting” hangs. This also happens right after a major app update before you re-launch.
How to verify: App Store / Play Store → check for a ChatGPT update. In-app, the waveform icon should sit at the bottom-right of the input bar; if it’s absent everywhere (including web), update and relaunch.
5. Browser tab denied the mic, or another app is holding it
On web:
- Chrome / Edge / Brave: the address-bar lock (or camera/mic) icon may show Microphone “Blocked” for
chatgpt.com - Safari occasionally auto-revokes mic access for sites you haven’t used in a while
- Another app currently using the mic (Zoom / Teams / Loom / Discord) can prevent ChatGPT from grabbing it
How to verify: address bar → site settings → Microphone → is it Allow? Quit other apps that may hold the mic, then retry.
6. Network blocks or throttles WebRTC
ChatGPT Voice is a realtime WebRTC session: it needs working UDP routing and steady bandwidth. VPNs, corporate firewalls, captive-portal hotel Wi-Fi, and some ad-blocking DNS can throttle or drop it. This is the classic source of Connection failed, tap to retry and mid-call stutter.
How to verify: switch off the VPN and try again, or move from restricted Wi-Fi to cellular. If voice connects on cellular but not on a given Wi-Fi, that network is blocking WebRTC.
7. An OpenAI-side incident
Occasionally voice is down for everyone. Before deep-diving, glance at the status page.
How to verify: check status.openai.com for an active Voice or ChatGPT incident. If one is open, wait it out — no local fix applies.
Shortest path to fix
Run these in order; most people are fixed by Step 1 or 2.
Step 1: Reset the OS mic permission
- iOS / iPadOS: Settings → Privacy & Security → Microphone → ChatGPT = On
- Android: App info → Permissions → Microphone → Allow
- macOS (browser): System Settings → Privacy & Security → Microphone → enable Safari / Chrome
- Windows: Settings → Privacy & security → Microphone → allow the ChatGPT app + browser
Then force-quit the ChatGPT app / close the chatgpt.com tab and reopen. The next tap on the waveform should re-prompt for permission.
Step 2: Switch the input device
- macOS menu bar → Sound → Input → pick “MacBook Pro Microphone” (not the headphones)
- iOS: Control Center → long-press the volume slider to check audio routing; switch output/input back to iPhone if needed
- Unpair Bluetooth headphones and test with the built-in or a wired mic
- Turn off Silent Mode and raise the media volume — voice replies use media output, not the ringer channel
Step 3: On a Mac, use the web app
The macOS desktop app no longer has voice (retired Jan 15, 2026). Open chatgpt.com in Safari or Chrome, allow the mic when prompted, and use the waveform button there.
Step 4: Update or fully reinstall the app
App Store / Play Store → update. If you’re already on the latest and it’s still broken:
- Sign out of ChatGPT
- Uninstall the app
- Restart the device
- Reinstall from the official store (don’t sideload an
.ipa/.apk) - Sign back in
Step 5: Cross-check web vs app
If the app fails, try chatgpt.com; if the web fails, try the app.
- Web works, app doesn’t → app version / OS permission (back to Steps 1 and 4)
- App works, web doesn’t → browser mic setting (Step 6 below)
Step 6: Fix the browser mic setting
Chrome / Edge / Brave:
Lock (or mic) icon in the address bar → Site settings → Microphone → Allow
Safari:
Safari → Settings for chatgpt.com → Microphone → Allow
Disable any extension that might mute, capture, or virtualize audio, then reload.
Step 7: Fix the network (WebRTC)
- Turn off the VPN, or switch to a different commercial VPN endpoint
- Move off restricted Wi-Fi (corporate / hotel) and test on cellular
- Get closer to the router to rule out weak signal
- If you keep seeing
Connection failed, tap to retry, the path is almost certainly blocking WebRTC UDP
How to confirm it’s fixed
Open a chat, tap the waveform icon, allow the mic, and say a short test sentence. You should see your words appear in the live transcript within a second and hear the model reply. If the transcript updates and ChatGPT speaks back, voice is working end to end — both the mic capture and the WebRTC return path are healthy.
Prevention
- Update the ChatGPT app on the same cadence as your iOS / Android updates
- Grant OS-level mic permission to both the app and your default browser
- On a Mac, bookmark
chatgpt.comfor voice — the desktop app won’t get it back - Don’t swap mic devices mid-conversation; many “broken voice” cases are a stuck Bluetooth route
- Run voice on stable Wi-Fi rather than walking on a weak cellular signal
- Keep a clean browser profile (no mute / privacy extensions) for heavy voice use
FAQ
- Is voice free now? Yes. Since 2025, ChatGPT Voice is included on every plan. Free users get it with a usage cap measured in hours per period; Plus, Team, and Enterprise are effectively unlimited. There is no separate “Advanced Voice” upgrade to buy anymore.
- Where did Standard / classic voice go? OpenAI retired the old speech-to-text → text → text-to-speech voice in late 2025 and merged everyone onto the single realtime ChatGPT Voice. If your old workflow relied on Standard voice, it no longer exists.
- Why is the waveform button gone on my Mac? Voice in the ChatGPT macOS desktop app was retired on January 15, 2026. Use
chatgpt.comin a browser on the Mac instead — voice still works there, on iOS, Android, and Windows. - It keeps saying
Connection failed, tap to retry. What now? That’s a WebRTC connection failure, not a mic problem. Turn off your VPN, switch networks (Wi-Fi to cellular), and check status.openai.com for an incident. - Why does voice lag or stutter? Realtime voice is sensitive to network quality. Weak Wi-Fi, a VPN, or a congested connection adds latency or drops audio; a wired connection or stronger signal usually fixes it.
