Putting a voicer on a PowerPoint slide

The PowerPoint add-in puts a live voicer right on a slide: the QR code your room scans and the one voice beside it, both updating as answers arrive.

# What the add-in puts on your slide

A PowerPoint slide filled by the voicer stage: a large QR code labelled “Scan to add your voice” with the share link under it, and beside it the question “What is your favorite thing about Washington State?” with the blended answer “We love the long summer days here.” and a count of 1 voice.
The voicer on a slide: the QR code your room scans on the left, the question and its live one voice on the right. Both stay live, the answer re-blends as voices arrive.

The add-in embeds your voicer’s stage, the same live view you can present from the app, directly on a PowerPoint slide. Your room sees the QR code, the question, and the one voice, and the answer keeps re-blending in real time as people scan in and reply. There is nothing to refresh and nothing to alt-tab to.

People answer on their own phones in the browser, so nobody in the audience needs PowerPoint, the add-in, or an account. Only the presenter installs anything.

# Installing the add-in

The add-in is free and is listed in the PowerPoint add-in store under the name OneVoicer, written as one word. In PowerPoint, open the add-ins dialog (Home tab, Add-ins, or Insert, Get Add-ins, depending on your version), search for “OneVoicer,” and add it. It works in PowerPoint on the web and in PowerPoint on Windows, Mac, and iPad.

The exact menu names move around between PowerPoint versions, so for the definitive walkthrough use Microsoft’s own guide:

Microsoft’s guide: view, manage, and install add-ins ↗

The Share it panel on a voicer’s page: a share link like app.onevoicer.com/v/… with an orange Copy link button, a QR code, and a “Present QR + answer” button.
The share link lives in the Share it panel on your voicer’s page. Copy link puts it on your clipboard, ready to paste into the add-in.

The link the add-in wants is your voicer’s share link, the same one you would send to a chat or a room. Open the voicer in One Voicer, find the Share it panel, and select Copy link. It looks like app.onevoicer.com/v/… and it works whether or not the voicer is live, so remember to go live before the room starts scanning: a voicer only collects voices while it is live.

# Choosing the voicer

The One Voicer pane on a PowerPoint slide: a card titled “Put a voicer on your slide” with a Share link field showing the placeholder https://app.onevoicer.com/v/… and an orange “Show on slide” button.
The add-in asks for one thing: your voicer’s share link. Paste it and select Show on slide.

When the add-in lands on a slide it asks for that share link. Paste it in and select Show on slide. The add-in only accepts One Voicer share links; if a link does not point at a real voicer it tells you right in the pane so you can fix it.

The choice is remembered in the presentation. Save the deck after adding the voicer, and reopening it later brings the same voicer straight back with no re-pasting. To show a different voicer, remove the add-in from the slide and insert it again with the new link.

# Presenting with it

During the talk the slide is the stage: the room scans the QR code, voices arrive, and the one voice re-blends before everyone’s eyes. It is the same voicer as everywhere else, so the voices your slide collects show up in the app, count toward the same blend, and land in the same history.

A share link is the only credential involved. Anyone who can see the slide can scan and answer, which is the point; if you want answers limited to signed-in people, set that on the voicer itself under who can respond.

# Frequently asked

Does my audience need the add-in too?

No. Only the presenter installs the add-in. The audience scans the QR code and answers in their phone browser, with no app and no account.

Which versions of PowerPoint work?

PowerPoint on the web, and PowerPoint on Windows, Mac, and iPad. If your PowerPoint can install add-ins from the Office store, One Voicer works in it.

How do I switch the slide to a different voicer?

Remove the add-in from the slide and insert it again, then paste the new voicer’s share link. Each inserted add-in remembers one voicer per presentation.

Do I need to sign in inside PowerPoint?

No. The share link is the credential. There is nothing to sign into in the pane, which is also why the add-in works in PowerPoint on the web.
