Zoom Live Captions: How to Turn On (Host)
If you host meetings on Zoom, turning on live captions is one of the simplest accessibility wins available: deaf and hard-of-hearing participants can follow along, non-native speakers get a reading aid, and everyone gets a text record of what was said. But the setting lives in two places — the Zoom web portal (account-level) and the in-meeting controls — and hosts routinely enable one while missing the other.
This guide covers both: the portal settings that make captions available, the in-meeting steps to turn them on as host, and the difference between automated captions and manual captioning.

The Two Places Captions Live
Understanding Zoom’s caption architecture prevents 90% of confusion:
- The Zoom web portal (zoom.us → Settings) controls whether captioning features are available — for your account, and optionally locked on for all users. This is an admin/host-side configuration step.
- The in-meeting controls turn captions on for a specific meeting. Even with portal settings enabled, someone — usually the host — must activate captions during the meeting.
If participants say “I don’t see a CC button,” the cause is almost always step 1: the feature isn’t enabled at the account level, so the in-meeting button never appears.
Step 1: Enable Captions in the Zoom Web Portal (Host/Admin)
Do this once — it unlocks captions for all your future meetings:
- Sign in to the Zoom web portal (zoom.us) as an admin or the account owner. Note: many caption settings require admin privileges; if you’re not an admin, ask yours to do this.
- Go to Settings → Meeting → In Meeting (Advanced).
- Find Automated captions and toggle it on. This enables AI-generated live captions.
- Find Manual captions and decide whether to enable it. Manual captions let a participant (or a hired captioner) type captions live. Enable it if you ever use professional CART captioning services.
- Optionally, click the lock icon to force the setting on for all users in the account — useful for organizations with accessibility policies.
- Check Full transcript settings if you want participants to be able to view/save the complete caption transcript, not just the live overlay.
Also verify: under Settings → Recording, confirm that caption/transcript saving options match your needs — this affects whether cloud recordings include transcript files (covered in our guide to downloading Zoom cloud recording transcripts).
Portal settings can take a few minutes to propagate. If the in-meeting CC button doesn’t appear immediately after enabling, wait a bit and rejoin.
Step 2: Turn On Captions During the Meeting (Host)
With portal settings enabled, the host activates captions per meeting:
- Start or join the meeting as host.
- In the meeting toolbar, click Show Captions (or the CC / Live Transcript button — the label varies by Zoom version; recent versions use “Show Captions”).
- Choose your caption mode:
- Automated captions — Zoom’s AI transcribes speech in real time. No extra setup.
- Manual captions — assign someone to type, or connect a third-party captioning service.
- Captions appear as an overlay at the bottom of the meeting window for everyone. Participants can toggle their own view, but the host controls whether captioning runs at all.
Host tip: turn captions on at the start of recurring meetings and they typically stay on for that meeting series. For one-off meetings, make it part of your opening checklist alongside “you’re on mute” reminders.
If the button is missing: you’re likely not signed in as the host, the portal setting isn’t enabled (Step 1), your Zoom client is outdated, or an admin has restricted the feature. Update the Zoom desktop client first — caption features are version-sensitive.
Automated vs Manual Captions: Which to Use?
| Factor | Automated captions | Manual captions (human/CART) |
|---|---|---|
| Cost | Included with Zoom | Typist or CART service (paid) |
| Setup | One click in-meeting | Assign a captioner or integrate a service beforehand |
| Accuracy | Good on clear speech; struggles with accents, jargon, crosstalk | Professional-grade; handles jargon, names, accents |
| Latency | Near-real-time (1–2 second delay) | Slightly longer delay (typist lag) |
| Speaker identification | Basic | Accurate |
| Best for | Internal meetings, everyday calls | Public events, legal proceedings, accessibility compliance needs |
The practical guidance: automated captions are fine for routine internal meetings — they dramatically improve on nothing. For public-facing events, recorded trainings, or any situation where caption accuracy has compliance or reputational weight, manual/CART captioning is worth the cost. Many organizations use automated for internal calls and professional captioners for webinars and all-hands.
Participant Experience: What Attendees See and Control
Once the host enables captions, participants get:
- Live caption overlay at the bottom of their Zoom window, toggleable via their own CC button.
- Full transcript panel (if enabled in portal settings) — a side panel showing the running transcript, which can be searched and saved by participants.
- Caption settings — participants can adjust caption font size in Zoom’s accessibility settings.
Hosts should mention captions in the meeting opening (“live captions are on — click CC if you’d like them”) because many participants don’t notice the button otherwise. For accessibility, this announcement matters: the participants who need captions most are the ones least likely to hunt through the toolbar unprompted.
Saving and Using the Transcript Afterward
Live captions can become a meeting record:
- If full transcript is enabled, participants can save the transcript during the meeting.
- Hosts can configure cloud recordings to include caption/transcript files (VTT) alongside the video — see our guide on downloading Zoom cloud recording transcripts for the exact steps.
- The transcript is a starting point, not a finished document: automated captions need cleanup (misheard terms, missing punctuation, no speaker labels beyond basics) before they’re useful as minutes or documentation. (Disclosure: TranscriptionAid is our own tool.) For turning a recorded meeting into a clean, readable transcript, our free browser-based transcription tool handles the audio-to-text conversion with timestamps.
Privacy note: tell participants when captioning and transcript-saving are active, especially for sensitive discussions. A saved transcript is a permanent record — make sure that’s the expectation, not a surprise.
Troubleshooting
“There’s no CC button in my meeting.” The account-level setting is off (Step 1), you’re on an outdated Zoom client, or you’re not the host/co-host. Check all three in that order.
“Captions are on but showing the wrong language.” Automated captions transcribe in the meeting’s spoken-language setting. Verify the language selection in the caption options — a mismatch here produces impressively wrong output.
“Automated captions are too inaccurate to use.” Common with heavy accents, technical jargon, or poor audio. Mitigations: ask speakers to use headsets, reduce background noise, speak one at a time — or switch to manual/CART captioning for the session.
“Participants can’t save the transcript.” The full-transcript save option is a separate portal setting from captions themselves. Enable transcript saving in Settings → Meeting → In Meeting (Advanced).
“Captions work on desktop but not mobile.” Participants need a current version of the Zoom mobile app; caption support on very old app versions is limited. Ask them to update.
Frequently Asked Questions
Do I need to be the host to turn on Zoom captions?
To start captioning for everyone, yes — host or co-host. Participants can toggle their own caption view once captioning is running, but they can’t initiate it. (Some Zoom plans/versions allow participants to request captions; the host still approves.)
Are Zoom’s automated captions free?
Automated captions are included — there’s no per-minute fee. Manual/CART captioning involves paying the human captioner or service separately.
How accurate are Zoom’s automated captions?
Comparable to other mainstream AI transcription: solid on clear, single-speaker English; degraded by accents, jargon, crosstalk, and bad audio. Treat the output as a live aid and a rough record, not a verbatim transcript — clean it up before it becomes documentation.
Can captions be saved automatically for every meeting?
Yes, via cloud recording settings: configure recordings to include the audio transcript (VTT) file. This requires the recording and transcript settings to be enabled in the portal — it doesn’t happen from the in-meeting CC button alone.
Do captions work in Zoom webinars too?
Yes. Webinar hosts enable captions the same way — portal settings plus the in-meeting control. For public webinars, consider manual/CART captioning for accuracy, since the audience is larger and the content is often recorded and redistributed.
What languages do Zoom automated captions support?
Zoom supports automated captions in multiple languages, with English the most mature. Check Zoom’s current support documentation for the full list — language coverage expands over time, and accuracy varies by language.
Conclusion
Turning on Zoom live captions as host is a two-step habit: enable automated (and optionally manual) captions once in the web portal settings, then click Show Captions at the start of each meeting. The whole thing takes under a minute per meeting and makes every call more accessible, more comprehensible, and better documented.
Make it part of your host checklist, announce it at the top of the call, and configure transcript saving for meetings worth keeping a record of. Your participants — especially the ones who’ve been quietly struggling to follow along — will notice.
