How to make your conference or event more accessible with live captions

Making an event accessible is not just about meeting technical requirements. It is about making sure more people can follow the conversation, understand the content, and participate without unnecessary barriers.

For conferences, workshops, panels, seminars, and community events, accessibility should be considered from the moment the venue is selected through the delivery of post-event materials.

Live captions are one important part of that process. They can make spoken content easier to follow for deaf and hard-of-hearing attendees, people listening in a second language, attendees in noisy environments, and anyone who benefits from reading along while listening.

But captions work best as part of a broader accessibility plan. Use this practical event accessibility checklist when planning your next conference or live event.

1. Start with venue accessibility

A truly accessible event starts before anyone walks into the presentation room. When evaluating a venue, look at the complete attendee experience.

Check whether the venue has:

• Step-free entrances
• Wheelchair-accessible seating areas
• Accessible restrooms
• Elevators for multi-floor venues
• Wide enough paths between tables and seating
• Accessible parking or nearby drop-off areas
• Clear directional signage
• Seating options for attendees with different mobility needs

Consider the route from the parking area or public transportation stop all the way to the event space.

An accessible entrance is much less useful if an attendee has to navigate stairs later to reach the presentation room.

For larger conferences, include accessibility information directly on the registration page so attendees can plan before arriving.

2. Make presentation slides easy to read

Conference accessibility also depends heavily on how information is presented visually. Slides filled with small text may be difficult to read even for someone sitting near the front of the room.

Keep presentations simple. Use short sentences, clear headings, and enough spacing between elements. Avoid placing large paragraphs on a single slide.

Presenters should also describe important visual information instead of assuming everyone can see the screen clearly. For example, instead of saying:

A presenter can explain the key takeaway:

That small change makes the presentation easier to follow for more attendees.

3. Use large text

Text should be readable from the back of the room. This applies to:

• Presentation slides
• Speaker names
• Room signage
• Schedules and menus
• Digital displays
• Live captions

There is no single font size that works for every venue, because screen size and viewing distance vary.

Test the presentation from the farthest likely seat. If reading the text takes effort, make it larger.

4. Use strong color contrast

Poor contrast can make otherwise good content difficult to read. Light gray text on a white background might look elegant on a designer's laptop, but it can become nearly unreadable when projected onto a conference screen.

Use strong contrast between text and its background. Examples include:

• Dark text on a light background
• White text on a very dark background
• Caption text displayed against a solid or highly opaque background

Avoid placing important text directly over busy photos or videos. Contrast matters most for live captions, because attendees need to read the text quickly while also paying attention to the speaker.

5. Require speakers to use microphones

One of the easiest ways to improve both conference accessibility and live caption accuracy is to improve the audio. Even speakers with loud voices should use a microphone.

The audience may include people who:

• Have hearing loss
• Are sitting far from the stage
• Are relying on live captions
• Are listening through assistive technology
• Have difficulty understanding speech in noisy environments

Microphones also provide cleaner audio to automated captioning systems. Ask presenters not to walk away from microphones while speaking.

During audience questions, avoid having attendees shout from their seats. Use a handheld microphone, a standing microphone, or repeat the question clearly into the speaker's microphone.

Better audio helps everyone.

6. Test audio quality before the event

Live captions are only as useful as the audio being captured. Before attendees arrive, test:

• Microphone volume
• Background noise
• Speaker distance from the microphone
• Audio from remote presenters
• Panel discussions with multiple microphones
• Videos played during presentations
• Internet connectivity for cloud-based captioning

Pay particular attention to panel discussions. When several people speak over each other, both attendees and captioning systems can have difficulty following the conversation. Encourage moderators to manage turn-taking and ask speakers to avoid talking simultaneously.

7. Make live captions easy to read

Adding captions is not enough. Attendees also need to be able to read them comfortably. Good live captions accessibility should consider:

• Font size
• Screen placement
• Contrast
• Number of lines displayed
• How quickly text disappears
• Whether speakers can be identified
• Whether attendees can access captions individually

Captions displayed only on a distant projector may not work well for every attendee. Someone sitting in the back of a large room may technically have access to captions while still being unable to read them.

Whenever possible, provide more than one way to view the caption feed.

8. Give attendees QR-accessible captions

One practical approach is to let attendees open the live captions on their own devices. Place a QR code somewhere easy to find, such as:

• The registration desk
• Event signage
• Presentation slides
• Table cards
• Printed programs

Attendees can scan the code and open the caption feed on their phone, tablet, or laptop — which lets them control their own viewing experience. Someone who needs larger text can hold the device closer. Someone sitting far from the presentation screen can follow along without reading across the room.

QR-accessible captions can also help when attendees move between rooms, or when an event uses screens that are hard to see from certain seats. Always test the QR code before the event begins.

9. Plan specifically for deaf and hard-of-hearing attendees

Captions for deaf attendees should not be treated as an afterthought added five minutes before a presentation. Include accessibility questions during registration — for example, an optional field asking whether an attendee requires accommodations.

Depending on the event and the needs of the attendee, accommodations may include:

• Live captions
• Sign language interpretation
• Assistive listening systems
• Reserved seating
• Accessible presentation materials
• Other communication accommodations

Do not assume live captions automatically replace every other accommodation. Different attendees have different communication preferences and needs. When possible, provide a clear contact method so attendees can ask accessibility questions before the event.

10. Explain how attendees can access captions

Do not make people search for accessibility features. At the beginning of the event, briefly explain that captions are available and how to reach them.

Include the same instructions on printed or digital event materials. Making accessibility features easy to discover is part of making them useful.

11. Provide post-event transcripts when appropriate

Accessibility does not have to end when the event does. A transcript can make presentations more useful for attendees who want to review material afterward.

Post-event transcripts can also help:

• Attendees review important details
• People find sections they missed
• Teams create meeting notes
• Organizers produce written summaries
• Attendees search for specific topics
• People who process information better through reading revisit the discussion

Before publishing a transcript publicly, review it for accuracy and confirm whether speakers expected the session to be recorded or distributed. Some events contain private, sensitive, or confidential discussions that should not appear in a public transcript.

Where Clear Transcribe AI can fit

There are different ways to provide live captions at an event, including professional captioning services, accessibility providers, conferencing platforms, and AI-powered transcription tools. Clear Transcribe AI is one option for events that want to turn spoken audio into live captions and make those captions available digitally.

One setup, two ways to read along

Display captions on the presentation screen while attendees also open the live transcript on their own devices from a QR code — useful when people are sitting at different distances from the screen. After a session, the saved transcript becomes a starting point for event notes or accessible follow-up materials.

Live transcription should still be tested before the event — particularly for speaker names, specialized terminology, accents, microphone quality, and noisy environments.

Live captions are one part of an accessible event

Creating accessible events is rarely about adding a single feature. Accessibility comes from removing barriers throughout the entire attendee experience: the venue, presentation materials, microphones, visual design, communication methods, captions, accommodations, and post-event resources.

Live captions can play an important role, especially for deaf and hard-of-hearing participants, while also making presentations easier for many other attendees to follow. The best approach is to build accessibility into event planning from the beginning rather than treating it as a last-minute addition.

The goal should be broader than checking a box. Make the event easier for more people to take part in.
