Live Captions Available in Teams Meetings

Live, Ad-Hoc Captioning Controlled by Teams Users

Office 365 Notification MC192383 posted on October 5 tells us that Microsoft is launching live captions for Teams meetings. The new feature is described in Microsoft 365 roadmap item 52817, which makes the important point that live captions only support English in the first release. Teams already supports captioning for Live Events, where producers of an event can choose six languages from over 50 for captioning. However, captioning on an ad-hoc basis poses different challenges to a structured planned event.

Enunciation and Good Headsets Critical for Captioning

Live captions exist to make meetings more accessible. In a face to face meeting, those who are hard of hearing might have some chance of following what people are saying, but this can be harder for video meetings if not everyone enables their camera or the video feed isn’t very good. To make live captions work, the audio feed is processed by voice recognition algorithms and the extracted text is displayed at the bottom of the screen.

I tried the new feature out in a call with Paul Robichaux (Figure 1) and discovered that it’s really important for speakers to enunciate clearly. Captions appear after a small but perceptible delay. Any slurring of words or mispronunciations or strong regional accents create challenges for voice recognition and end up with some interesting but inaccurate captions. It’s also true that good headset microphones are important to ensure that the best quality audio feed is available for processing. Further tips for achieving captioning accuracy are available in the documentation for live captions.

Live captions aren’t turned on automatically. Meeting participants must select Turn on live captions(preview) from the […] menu after joining a meeting.

Live Caption Setting in Teams Meeting Policy

Like many other Teams features, the ability for people to use the live captions feature is controlled by a policy assigned to their account. In this case, it’s the Teams meeting policy. Unfortunately the description about enabling or disabling live captions in the Office 365 notification is garbled. Here’s what happens.

The LiveCaptionsEnabledType setting in the Teams meeting policy controls if a user can enable live captions. If the settings is Disabled, the user can’t enable live captions. If it is DisabledUserOverride, live captions won’t be enabled at the start of a meeting but the user can enable the feature after they join. Notification MC192383 says that live captions is enabled by default for your tenant, but when I checked, I found that a number of meeting policies had the setting disabled:

# Get list of Meeting policies in the tenant 
Get-CsTeamsMeetingPolicy | ft identity, live*

Identity                           LiveCaptionsEnabledType
--------                           -----------------------
Global                             DisabledUserOverride
Tag:RestrictedFunctionality        Disabled
Tag:AllOn                          EnabledUserOverride
Tag:RestrictedAnonymousAccess      Disabled
Tag:AllOff                         Disabled
Tag:RestrictedAnonymousNoRecording Disabled
Tag:Default                        Disabled
Tag:Kiosk                          Disabled

You can update the meeting policies that have live captions disabled through the Teams Admin Center (Figure 3).

Profanity Filter

A recent LinkedIn post by Patrick Kelley, a Teams customer success black belt (quite a title) at Microsoft, discussed a profanity filter for live captions. Apparently, the filter has the ability to detect terms like “kiss my ass” and suppress the offending words (Figure 3).

Unfortunately, despite spirited attempts by Paul and myself to invoke the profanity filter, Teams declined to do so and the voice recognition algorithms made the best of our cussing. Perhaps it was our accents, or that we didn’t swear fluently enough. Or that the feature just hasn’t been released outside Microsoft. In any case, beside Teams live captions only supports English currently, you’ll still be able to shock people with a perfectly formed insult in French, Spanish, Italian, or any other non-English language you choose to use.

  1. Can I have the transcript of the Live captions and save it for later reference after the meeting? If yes, how to do that?
    It will be really useful for quick look what was said.

      1. My organization has made it recording of teams meeting as paid service. Can I just get the captions saved in a file (local or on cloud which I can download) without explicitly recording the complete teams meeting?

      2. The captions are created by Stream when it processes a video. The captions then form the transcript. Without the recording, neither is available.

  2. Hi,
    Is there anyway to increase the number of lines display for captions. It is currently displaying 2 lines. I am hearing impaired and captions scroll off too quickly. Have just start using this function.

  3. We use the live captioning extensively internally to our business, it’s helpful for all attendees. But for externals joining our meetings via the web option, they do not get the option of live captions. Is there a way for us to enable Live captions for our external partners who join the meeting via the web?

  4. Can we or will we be able to trigger live caption for unscheduled calls between Team users? Either done directly or thru the Team/channel they have joined? Right now, it is available only for scheduled meeting.

  5. Hi – I have a hearing impaired colleague and it would help if she could type her comments into the captions field as the captions cannot interpret her speech successfully – is this possible? Putting her remarks in the chat panel is too disjointed…

    1. I’m afraid not. The chat panel is the only available method to type in comments that become part of a conversation. I do this all the time to enter information that I want to be discussed and it works well if someone takes care to read back over the chat and resolve anything that’s there which hasn’t been discussed and answered before the meeting closes.

  6. Can we increase the height of the captions bar in Team? At the moment can only see two lines, and if multiple people talking, you need more lines to be showing.
