BYOD Captions: Live Captions on Attendees' Own Phones

BYOD captions mean live captions that people read on their own phones, tablets or laptops. BYOD stands for “bring your own device.” The speaker talks, software turns the speech into text, and attendees scan a QR code to follow along in a browser. No headsets to hand out. No receivers to rent. No app to install.

This guide explains how it works at a church, a meeting or an event. It covers what you need in the room, what it costs, how accurate automated captions are, and when you should bring in a human captioner instead.

TL;DR

• BYOD captions send live text to the devices people already carry. Attendees scan a QR code and read along.
• Live Caption AI runs on the speaker’s phone or laptop. Attendees need no app and no account. The Professional plan is $19.99 a month.
• Good captions depend on a clean microphone feed, working Wi-Fi or cellular coverage, and a test before doors open.
• Automated captions are AI captions. For public events or a formal accommodation request, many universities call for human captioners.
• Live translation into one of 29 languages per session helps multilingual rooms.

What BYOD captions mean in practice

Traditional captioning at a live event needed gear. A screen at the front. A stenographer on site or on a remote line. Sometimes dedicated receivers for people who needed them.

BYOD flips that. The display is the phone in each person’s pocket. That has three practical effects:

• Everyone reads at their own pace. They can sit anywhere, hold the phone close, and read without craning at a distant screen.
• Text size is personal. Each person adjusts to what works for their eyes.
• Nothing to return. There is no equipment to sanitize, count or collect after the event.

Who uses it? Churches that want every member of the congregation to follow the sermon. Event organizers who want captions without booking a person weeks ahead. Teachers and meeting hosts with a mixed audience. AV companies that run multilingual events for clients.

BYOD captions are different from open captions on a big screen. Open captions are visible to everyone. BYOD captions are opt-in: people who want them scan and read, and everyone else sees nothing extra. Many organizers do both: a QR code on the screen or program, and a screen for those who prefer it.

How BYOD captions work with Live Caption AI

Live Caption AI puts live captions on every phone in the room through a QR code. Here is the flow.

1. The speaker starts a session. They open Live Caption AI on a phone or laptop and pick a vocabulary model if one fits.
2. The app shows a QR code. Put it on a slide, a printed card, a lobby sign or the back of a program.
3. Attendees scan it. Their phone opens the captions in a browser. No app to install. No account to create.
4. Captions stream live. Anyone in the room reads along on their own screen.
5. The session ends. The transcript is saved automatically to the speaker’s account.

That is the whole setup. No hardware to rent. No stenographer to book.

Attendees are not limited by number of devices. Unlimited captioning on the Professional plan means you can run long services, back-to-back sessions and full-day conferences.

For a deeper walkthrough of event setup, see our practical setup guide for in-person event captions. If you plan a larger program, our post on adding live captions and booking two weeks out covers the timeline.

What you need in the room

BYOD captions look simple to attendees. Behind the scenes, three things decide whether they work well: the audio, the connection and the preparation.

A clean microphone feed

Captions can only be as good as the audio they hear. A speaker’s phone placed across a noisy room will struggle. A direct feed or a close microphone will do far better.

The Los Angeles Department on Disability makes the same point in its guidance on remote captions for in-person events: a reliable microphone feed, stable internet, advance testing and an assigned staff member all matter.

Practical tips:

• Use a lapel or handheld microphone close to the speaker’s mouth.
• Ask panelists to pass the microphone, or use one per person.
• Cut background music while someone speaks.
• Ask speakers to talk at a natural pace and finish one thought before the next.

Internet or cellular coverage

Attendees’ phones need a way to receive the captions. That means Wi-Fi or a cellular signal. The speaker’s device needs a connection too.

UC Berkeley’s live captioning checklist for in-person events tells organizers to check web access at the venue, confirm internet or cellular coverage, and check access before the event. Follow that. Walk the room, including the back rows and any overflow space, with your own phone.

If the venue Wi-Fi is crowded, say so on the sign: “Scan for captions. Cellular data works too.” Many people will simply use their own data plan.

A test before doors open

Test 15 to 30 minutes early. Start a session, say a few sentences, scan the QR code from the back of the room, and read what appears. Our guide for event hosts on broadcasting captions to phones walks through the test.

Also assign one person to own captions during the event. If something drops, that person knows what to do.

A visible QR code

A QR code nobody sees helps nobody. Place it where people look:

• On the opening slide and repeated at section breaks
• On a printed card at every seat or table
• On the welcome sign or lobby screen
• In the bulletin, program or event email

Add a one-line instruction next to it. “Point your phone camera here to read live captions.”

Checklist: your first BYOD captioned event

Getting names and specialized words right

Generic speech-to-text often garbles names, places and specialized terms. That is where most complaints about automated captions come from.

Live Caption AI addresses it in two ways.

Vocabulary models. We offer a Medical model, a Worship & Ministry model and a Finance & Earnings model. Pick the one closest to your content before you go live. We do not offer a legal or technical vocabulary model.

Custom Terms. The speaker can type in up to 100 names, places and terms before going live. Think of the pastor’s guest speaker, a missionary’s village, a product name, a board member, a program title.

A few tips for Custom Terms:

• Add proper names first. They are the hardest for any speech engine.
• Add the spelling you want to see on screen.
• Add acronyms your audience knows but a general model might not.
• Update the list for each event.

The model suits the subject, not the setting. A Medical model helps with terminology in a health-related talk. It is not a certification for clinical use, and we do not present it that way.

How accurate are automated captions?

Automated captions have improved a lot. They are not perfect.

In one academic study of automatic captions from a single provider, average accuracy was 98.56% in English and 98.26% in Spanish. The same study found colloquial content with several speakers was harder. That matches what organizers see: one clear speaker on a good microphone is the easiest case. A lively panel with people talking over each other is the hardest.

How to get the best results from AI captions:

• One speaker at a time. Set ground rules for panels and Q&A.
• Repeat audience questions into the microphone before answering.
• Use the right vocabulary model and add Custom Terms.
• Keep audio clean. No echo, no hum, no loud background music.
• Review the transcript afterward and correct anything you plan to publish.

Live Caption AI is an AI captioning tool. It is not a certified or human-reviewed service. We say so plainly so you can plan your event with the right expectations.

ADA, accessibility and when a human captioner fits

The Americans with Disabilities Act expects organizations to communicate effectively with people who have hearing disabilities. Which aid is right depends on the situation, and the person who needs it matters.

Live Caption AI can be one part of an organization’s ADA effective-communication plan. It does not make an organization ADA-compliant on its own, and we do not offer an ADA certification.

Many universities draw a firm line between everyday AI captions and formal accommodations:

• The University of Colorado says automated tools are not sufficiently accurate for public live-streamed events or accommodation requests, where human-created captions should be used.
• Harvard’s accessibility office notes that auto-generated captions have lower accuracy than live transcribers and suggests CART, which is human live captioning, for important meetings and events.

So how do you decide? Think about the stakes and the person.

This is why researchers Pablo Romero-Fresco and Yanou Van Gauwbergen describe automatic and human captions as serving different purposes: AI for “bulk access” and humans for “curated access”. The two can coexist depending on how critical the setting is. For a wider look at how AI sits next to human expertise, see this piece on AI alongside human teaching expertise.

Live Caption AI is not suitable or certified for courtroom or clinical use. If your event is one of those, plan for a human captioner. If you are not sure which rules apply to your organization, ask your counsel or your accessibility coordinator.

Translated captions for multilingual rooms

BYOD works well for translation because each person chooses what they read.

Live Caption AI translates into one of 29 languages per session. The speaker picks one source language and one target language. Viewers can switch between the original and the translation on their own phone.

What that means for you:

• One target language per session. If your room needs Spanish, set Spanish. If you also need a second language, plan a separate session.
• Captions only. Translation appears as text. We do not offer translated audio or text-to-speech.
• Bilingual readers can switch. A viewer who wants to check a term can flip back to the original.

Checklist for multilingual events:

• Ask registrants which language they need before the event.
• Add names and place terms as Custom Terms so they stay consistent.
• Put the QR code in both languages on your signage.
• Test the translation with a native speaker if you can, before the audience arrives.

Other tools exist for this. For example, the University of Colorado notes that Microsoft Translator lets attendees join by code and view translated live captions. The BYOD idea is the same: a code, a phone, a browser.

Translation uses credits. In-app credit packs are one-off purchases: 30 credits for $6.99, 60 credits for $11.99, or 120 credits for $19.99. See the pricing page for how credits apply to your plan.

What BYOD captions cost

Compare BYOD software to the usual alternatives by type.

• Hardware systems. Receivers, loops or dedicated screens. You buy or rent equipment and manage it at every event.
• Human captioners. Highly accurate and often required for formal accommodations. They also need booking in advance and a fee for each event.
• BYOD software. A subscription. Attendees use the phones they already own.

Live Caption AI pricing, as published:

The Free plan gives you basic on-device captions. Paid plans unlock cloud-based features and advanced functionality. Check the pricing page for the current plan details.

For a church running services every week, the math is simple: one flat monthly price, unlimited captioning, no per-event booking.

Transcripts, privacy and what happens after the event

Your captions do not vanish when the session ends.

• Transcripts save automatically. Every session’s transcript is saved to the speaker’s account.
• Only the speaker can read them. Transcripts are readable only by the speaker.
• You can delete them. Speakers can delete their transcript from History.
• Audio is never stored. Live Caption AI never stores session audio. We do not offer audio recording or playback.
• Export what you need. Save transcripts as TXT, SRT, JSON or PDF. AI summaries are included.

Exports are useful after a sermon, a training or a town hall. Post the text, share the summary with people who missed it, or use the SRT file with a video you edit later.

If your organization handles sensitive information, set your own rules about which sessions to caption. Live Caption AI is not HIPAA-compliant, and we do not offer a Business Associate Agreement.

Our perspective

We built Live Caption AI around one idea: captions should reach people where they already are, on the phone in their hand.

Most churches and event teams we hear from are not trying to cut corners. They want more people to follow along, and they do not have a budget for hardware or a captioner at every service. A QR code solves the access problem on day one. Nobody downloads anything. Nobody makes an account.

We also think honesty is part of good accessibility. Live Caption AI is AI captioning. It is not certified and it is not human reviewed. So we focus on what makes AI captions better: a Medical, Worship & Ministry or Finance & Earnings model, up to 100 Custom Terms for the names your speaker will actually say, and a clear test routine before you go live.

Used that way, BYOD captions put useful text in front of the whole room, every week, at a price a small organization can carry. For the moments that call for a human captioner, you can plan for that too. The two work side by side.

FAQ

Do attendees need to install an app for BYOD captions?

No. With Live Caption AI, attendees scan a QR code and read captions in their phone’s browser. They do not install an app or create an account. The speaker runs Live Caption AI on a phone or laptop.

What equipment do I need for BYOD captions?

You need a device for the speaker, a good microphone feed, and Wi-Fi or cellular coverage in the room. You do not need receivers or screens for attendees. Test the setup 15 to 30 minutes before the event.

Are AI captions enough for ADA requirements?

It depends on your situation. Live Caption AI can be part of an organization’s ADA effective-communication plan, but it does not make an organization ADA-compliant on its own. For public live streams or a specific accommodation request, many institutions call for human captioners. Ask your counsel or accessibility coordinator.

Can BYOD captions be translated?

Yes. Live Caption AI translates into one of 29 languages per session. The speaker picks a source language and a target language, and viewers can switch between the original and the translation.

Does Live Caption AI keep a recording of my event?

No audio is stored. The transcript is saved to the speaker’s account and is readable only by the speaker, who can delete it from History at any time.
