Live Captions for Church Services and Sermon Transcription

Live captions for church services and sermon transcription both turn spoken words into text, and both make church more accessible: for people with hearing loss, for those listening in a second language, and for anyone who wants to follow or revisit the sermon. Captions put that text in front of the congregation or online viewers; a live transcript can also help the media team behind the scenes. OpenMico provides the second of these, an operator-facing live transcript that it uses to spot Bible references as the preacher says them.

This guide explains why captions and transcription matter, the choice between on-device and cloud transcription, how to get a clean microphone feed, and exactly what OpenMico does with a live transcript.

Why should churches think about captions and transcription?

Spoken words are at the centre of most services, yet not everyone can follow them easily.

• People with hearing loss. Hearing loops and good sound help, but text gives another way in, especially in rooms with echo or for people who rely on lip-reading.
• Second-language listeners. Many congregations include people who read English more comfortably than they follow fast speech. Text lets them catch up at their own pace.
• Online viewers. People watching on a phone may have the sound low or off, or be in a noisy place.
• Sermon notes and follow-up. A written record of what was said can help small groups, volunteers preparing summaries, and people who missed a week.
• Children and new visitors who may find it harder to concentrate on a long talk.

None of this replaces good sound, clear preaching or a welcoming team. It simply removes one more barrier for people who want to take part.

What is the difference between live captions and sermon transcription?

The terms overlap, but it helps to separate them.

OpenMico falls into the middle column. It listens to the sermon and shows a live transcript to the operator, then uses that transcript to detect Bible references. It does not send captions to your screens or livestream. If you need on-screen or online captions, use a dedicated captioning tool or check the caption features of your streaming platform; some third-party tools, such as Glossa AI, provide captions alongside other presentation software.

On-device or cloud transcription: which should you use?

Speech-to-text runs either on your own computer or on an online service. OpenMico offers both.

On-device transcription

On-device transcription runs on the presentation computer itself. In OpenMico it is included free and unlimited.

• Strengths: no ongoing cost, and the audio is processed on your own machine.
• Things to consider: accuracy depends on the computer and the audio quality, so test it with your own preacher and room.

Cloud transcription

Cloud transcription sends audio to an online service for processing. OpenMico offers it alongside on-device transcription, so you can compare the two in your own room.

• Strengths: processing happens on the service, not your computer, so results do not depend on how powerful the media computer is.
• Things to consider: it needs a working internet connection. Every OpenMico account with a verified email gets a one-time 90 free minutes of cloud transcription; after that it is unlimited on the Pro and Max plans. See pricing for current plan details.

A sensible approach is to start with on-device transcription, test it for a few weeks, and try cloud transcription with the free minutes to compare in your own building.

How should you place microphones for accurate transcription?

Whichever engine you choose, the biggest factor in accuracy is the audio you feed it. A clear voice with little background noise transcribes well; a distant voice in a reverberant room does not.

1. Use the preacher's own microphone. A headset or lapel microphone close to the mouth gives the cleanest signal. A lectern microphone works if the preacher stays near it.
2. Take a direct feed from the mixing desk. Send the preacher's channel (or a dedicated auxiliary mix) to the presentation computer, rather than using a microphone that picks up the whole room.
3. Keep music out of the feed. If the band plays under the sermon or during prayer, a feed with only the speech channel will transcribe far better than the main mix.
4. Set a healthy level. Too quiet and words are missed; too loud and the signal distorts. Check the level during a rehearsal.
5. Avoid the built-in laptop microphone except as a last resort. It hears fans, keyboards and the room.
6. Use a reliable audio interface or input on the presentation computer, and label the cable so nobody unplugs it.
7. Test with the actual preacher before the service. Voices, pace and accents vary. Add the check to your Sunday media team checklist so it happens every week.

The listening documentation explains how to choose the audio input and set up speech in OpenMico.

How does OpenMico use the live transcript for verse detection?

This is where an operator-facing transcript becomes practical rather than just useful.

Spoken Bible-reference detection (every plan)

When the preacher says a reference aloud, such as "John 3:16" or "Romans chapter eight", OpenMico detects it from the transcript and queues it in Preview. The operator sees it, checks it is the passage the preacher means, and sends it live at the right moment. Automatic projection can be switched on, but it can also be left off, and we recommend leaving it off while you rehearse so you can review references first.

AI scripture recognition from descriptions (Pro and Max)

Preachers often describe a passage rather than cite it. On the Pro and Max plans, OpenMico's AI recognises described passages too: "the night Jesus calmed the storm" points to Mark 4:39, and "Paul's list of the fruit of the Spirit" points to Galatians 5:22.

The operator stays in charge

Every detected or AI-suggested reference is checked against the installed Bible before it can be shown, and the operator always decides what goes live. The transcript is a tool to help the media team keep up, not a replacement for their judgement. You can read more about how this works on the AI Bible verse detection page and in our explainer on automatic Bible verse detection.

How can churches offer captions alongside OpenMico?

If accessibility captions are a priority, you can combine tools:

• Use OpenMico for presentation and verse detection, with the live transcript helping the operator.
• Use a dedicated captioning tool or your streaming platform's caption features for congregation-facing or online captions.
• Keep the audio feed shared. The same clean speech feed from the desk benefits both.
• Tell people captions are available, in notices and on your website, so those who need them know where to look.
• Ask for feedback from people who use captions. They will tell you quickly whether the text is readable and accurate enough.

Whatever you choose, check privacy expectations with your leadership, especially if audio is processed online, and let the congregation know how services are recorded or transcribed.

Getting started with transcription

Captions and transcription are a practical way to make services easier to follow for more people, and a clean microphone feed is the foundation for both. OpenMico's on-device transcription is free and unlimited, spoken Bible-reference detection is on every plan, and the operator always stays in control of what appears on screen.

To try listening and verse detection with your own preacher, download OpenMico for free and run it during a rehearsal with automatic projection switched off.
