How to Enable Live Captions and Real-Time Translated Subtitles in Microsoft Teams

In modern hybrid workplaces and distributed multinational enterprises, attending video conference meetings frequently involves communicating across diverse accents, foreign languages, and challenging auditory environments. Meeting attendees who are deaf or hard of hearing, participants joining from loud transit spaces, and non-native speakers often struggle to follow rapid dialogue or technical jargon. To enhance accessibility and global collaboration, Microsoft Teams provides integrated Live Captions and AI-powered Real-Time Translated Subtitles.

Leveraging Microsoft’s Cognitive Services speech recognition, Teams transcribes spoken dialogue into on-screen subtitles in real time, clearly attributing dialogue to specific speakers by name. With translated captions, participants can simultaneously read subtitles translated live into over 40 global languages. In this guide, you will learn how to turn on live captions, customize speaker attribution and typography, configure live language translation, and troubleshoot caption settings in Microsoft Teams.

Key Features of Microsoft Teams Live Captions

Teams subtitles offer comprehensive meeting assistance:

• Automatic Speaker Attribution: Identifies which meeting participant is currently speaking, displaying their name, profile avatar, and timestamp alongside the text.
• Real-Time Translation: Allows individual meeting participants to read subtitles in their personal native language (such as translating spoken French into English, Spanish, or German text) without altering what other attendees see.
• Privacy-Conscious Processing: Live captions are generated on the fly and are not stored as meeting records unless meeting recording or formal transcription is deliberately initiated.
• Customizable Presentation: Tailor font size, line height, subtitle color contrast, and position to prevent subtitles from obscuring shared slide decks.

Step 1: Enabling Live Captions During a Microsoft Teams Meeting

Live captions can be activated at any point during a scheduled or ad-hoc Teams call:

1. Join your Microsoft Teams meeting from the desktop app (Windows or macOS) or the web client.
2. In the meeting controls toolbar at the top of the window, click the More button (•••).
3. Hover over or click Language and speech.
4. Click Turn on live captions.
5. A subtitle pane appears immediately at the bottom of the video window, streaming speech as dialogue occurs.

Step 2: Confirming the Spoken Language of the Meeting

For the speech engine to transcribe words accurately, it must know what language attendees are speaking:

1. At the right side of the active caption toolbar at the bottom of the screen, click the Caption settings (three dots •••).
2. Select Change spoken language.
3. Choose the predominant language spoken in the call (e.g. English (United Kingdom), French (France), Japanese, or Spanish (Spain)).
4. Click Confirm. All participants benefit from the improved transcription accuracy of the selected speech model.

Step 3: Turning On Real-Time Translated Subtitles

If you are attending an international call where participants are speaking a language you do not speak fluently, you can translate their speech into your personal language in real time (available with Teams Premium and select Microsoft 365 Enterprise plans):

1. In the caption controls area at the bottom of the screen, click Caption settings (•••).
2. Hover over Subtitles.
3. Click your desired target translation language (for example, select French if colleagues are speaking English, or English if colleagues are speaking Mandarin).
4. Teams instantly converts the spoken audio into translated text on your personal screen, while other attendees continue viewing their own chosen subtitle language.

Step 4: Customising Caption Styling, Font Size, and Layout

To ensure captions remain legible without obstructing shared presentation slides:

1. Click Caption settings (•••) in the caption bar.
2. Select Caption styles.
3. Adjust your visual preferences:
   • Colors and contrast: Choose between dark background with white text, high-contrast yellow on black, or transparent overlays.
   • Font size: Select Small, Medium, or Large depending on your display resolution and eyesight preferences.
   • Position: Toggle between anchoring subtitles at the bottom of the video grid or displaying them as a vertical side panel alongside the chat.

Enabling Live Captions on Teams Mobile (iOS & Android)

When participating in Teams meetings on your smartphone:

1. During an active video call, tap the screen to reveal controls and tap the More options (•••) button in the bottom-right corner.
2. Tap Turn on live captions.
3. Captions render smoothly across the lower third of your mobile display. Tap the gear icon to adjust language and typography.

Troubleshooting Teams Live Captions

• Captions Option Greyed Out: Your organization’s IT administrator may have disabled live captions in the Microsoft Teams Admin Center under Meeting policies > Recording & transcription > Live captions. Contact your tenant administrator to enable the policy.
• Inaccurate Transcriptions: Ensure the Spoken language setting matches the primary speaker’s regional dialect. External noise and muffled headset microphones also degrade speech-to-text accuracy; encourage speakers to use headsets with directional microphones.
