The First-Timer's Guide to Setting Up Live Translation at an Event

You're organizing an event where not everyone speaks the same language, and it's on you to make sure they can all follow along. Live translation on your audience's own smartphones is how most organizers solve this now, and setting it up is more straightforward than you'd expect.

This guide walks you through the whole process, step by step, for any format: a conference, a church service, a guided tour, a training, or a hybrid session. The setup is largely the same for all of them.

You'll create your event, choose between human interpreters and AI translation, get clean audio in, and get your audience connected, whether you're expecting 60 people or 2,000. And the payoff: you'll be able to offer a simple way for your international crowd to follow along in their own language.

The setup at a glance

Here's the entire process in five steps. Each one is expanded below.

1. 1.
   Decide who interprets: human interpreters, AI translation, or both.
2. 2.
   Create your event and add a language or AI channel for each language.
3. 3.
   Get the speaker's audio into LiveVoice with a microphone or the venue's audio desk.
4. 4.
   Share the event with your audience by QR code, link, or 6-digit code.
5. 5.
   Run a sound check, then go live and watch the listener count climb.

For a first-timer the whole thing takes about 15 minutes. You can run every step yourself, and if you'd rather have a hand, LiveVoice offers support services for planning, setup, and interpretation.

Step 1: Decide who interprets: humans, AI, or both

Short answer: use human interpreters when nuance and stakes are high, AI translation when you need flexibility, many languages, or have a smaller budget, and combine the two when different languages call for different things. Decide this first, because it determines what kind of channel you create in the next step.

This is the one genuinely strategic choice in the setup, and it's important that you are aware of the strengths of each option.

Human interpreters are the better call when:

• The content is highly sensitive and precision matters.
• Speakers are fast, use slang or local dialects, or switch registers, like live panels and Q&A.
• The audience will act on the content in a high-stakes way, such as negotiations or investor briefings.
• Cultural nuance carries the meaning. A quick example: the German word Opfer means both "sacrifice" and "victim." A human picks the right one from context while AI doesn't always get it right.

AI translation is a strong fit when:

• The content is fairly predictable: keynotes, product talks, guided tours, worship services.
• You need many languages at once. A single audio stream can become 10, 20, or 30 languages.
• Budget or short notice rules out booking interpreters.

And you can run both in the same event: human interpreters for your main languages, AI translation for the long tail of smaller language groups.

Human interpreters stream from anywhere, with no booth required. Reach out to us if you need an interpreter, we have an extensive network of available interpreters.

Step 2: Create your event and language channels

Now create the event and add one channel per language. The type of channel depends on the choice you just made.

Log into LiveVoice and create a new event with a name and date. One speaker talks, and each channel carries that speech in a different language, so attendees simply pick the one they want. For each language you need, add a channel:

• For a language handled by a human interpreter, add an audio input channel that the interpreter streams into. Invite them with a speaker link or a 6-digit code, and they can work from anywhere.
• For a language handled by AI, add an audio input channel first which serves as the source channel. Then you can add AI channels and define their target languages. You can also use the AI Quick Setup option. With AI Quick Setup you can simply define the source language and target languages and the event will be created with all channels automatically within seconds.

Step 3: Get the speaker's audio into LiveVoice

The one thing LiveVoice needs to work well is clean audio reaching the device you're running it on, whether that's a laptop or a phone. How you capture it follows the choice you made in Step 1.

Working with on-site human interpreters? Use a headset. A combined headphone-and-microphone headset, plugged into a phone or computer, is the standard setup: the interpreter listens to the floor and speaks the translation into the mic. (A single speaker or tour guide talking directly into LiveVoice uses the same thing.) Connect it by USB-C, Lightning, a 3.5mm jack, or Bluetooth. Because the mic sits right by the mouth, the audio stays clean. LiveVoice has headset recommendations if you want specific models.

Using AI translation or remote interpreters? Feed it the stage audio. The AI and remote interpreters translate from the original audio, so on a mic'd stage you take the signal from the venue's mixing console into your laptop with a USB audio interface. No mixing console? A headset or USB mic on the speaker works for AI too. For AI translation audio only is enough. For human interpreters you will want to send a video feed as well. In this case activate the video feature for the source (floor) channel and connect a video camera to your sending laptop.

Running both? Do both: headsets for your interpreters, and a stage feed for the AI.

One thing to skip: leaning on the laptop's built-in microphone to pick up the room. From a few feet away it grabs the air conditioning and the crowd along with the speaker, and the translation suffers for it.

Step 4: Share the event with your audience

Participants listen through the free LiveVoice app (iOS, Android, Huawei), with no account to create and nothing to sign up for. They install it once, open your event, and pick their language. The app keeps the audio playing in the background, so listeners can lock the screen and drop the phone in a pocket without losing the stream.

The part organizers underestimate isn't the technology. It's making the join step obvious enough that people actually do it. You have three ways to share:

• QR code, best for in-person. Put it on the screen, in the printed program, and on table tent cards. Make it at least 4×4 cm in print, test it on a few phones first, and leave it up on screen, including after breaks. A QR code only helps if people can scan it, so the one flashed for four seconds between slides doesn't count.
• Direct link, best for hybrid and remote. Send the session URL by email, SMS, or your event app. Ideal when remote attendees need access too.
• 6-digit code, the reliable fallback. Read it out from the stage, print it in the bulletin, or text it around, and participants type it on the join page.

LiveVoice also gives you ready-made text templates to paste into an email or your website, and you can share by location too. See simple sharing for all the options.

On headphones: most people already carry earbuds, and any Bluetooth or wired pair works. One catch: phones without a headphone jack need a USB-C or Lightning adapter for wired earbuds, so Bluetooth is simpler. Want to make sure everyone's covered? You can order headphones from LiveVoice and rent adapters to have sent ahead of your event, or set out a box of inexpensive earbuds at the registration desk for anyone who forgot theirs.

When participants open the event, they see a list of languages. They pick one, press play, put in their earbuds, and hear the event in their own language. For a big room, station a volunteer near the entrance for the first ten minutes; a small share of people might want some initial help.

Step 5: Run a sound check, then go live

Never skip the rehearsal. It's the best way to walk in relaxed.

We recommend to do the rehearsal a day before the event so if you run into any issues you still have time to react. And it makes sense to do a final quick test 30 minutes before doors open, not while people are already seated:

1. 1.
   Connect your audio source and select it in the LiveVoice dashboard.
2. 2.
   Do a 30-second sound check: speak, and confirm the level meter is active and the interpreter (or AI translation) is receiving the signal.
3. 3.
   Listen to the output on your own phone. The speaker should come through clearly, well above any room noise. If it's distorted, nudge the mixing-board gain down; if it's faint, ask AV to bring the line-out up. If you hear more room than speaker, you're on a mic that's catching the space, so switch to a direct board feed or move the mic closer and turn on noise suppression.
4. 4.
   Confirm each interpreter is connected and routing to the right channel.
5. 5.
   Display the QR code, start the event, and you're live.

From here, attendees can join anytime. The dashboard shows a live listener count and active channels, so you can see it working in real time. As mentioned, a day or two before the event, do a full dry-run with your team. LiveVoice's free test plan supports up to three participants and 20 minutes of AI translation, which is enough to rehearse the audio feed and the join flow end to end. There's also a printable on-site checklist you can hand to a volunteer.

What internet connection do you need?

Very little, which surprises most first-timers.

Each listener's stream uses only 0.06 Mbit/s, so 150 people listening at once fit comfortably on a standard 10 Mbit connection, and a full hour uses roughly 25 to 30 MB of mobile data. Latency runs around 200 ms, so for someone in the room it's essentially real time.

Two things are worth planning:

• The interpreter's and operator's connection is the critical one. If it drops, everyone hears silence. It doesn't need to be fast, but it does need to be stable and dedicated: a wired connection, or a WiFi network separate from the one hundreds of participants are sharing. No dedicated option? A 4G/5G hotspot beats crowded event Wi-Fi.
• Watch out for Wi-Fi login pages. If your venue Wi-Fi shows a "captive portal" sign-in, attendees can struggle to connect mid-session. Test the join flow on that network before doors, or simply tell people to use mobile data. The data use is tiny, so mobile is fine. For more, see LiveVoice's internet connection tips.

What does it cost to run?

There are no per-event fees. You pay for an account plan, plus AI translation by the minute if you use it.

LiveVoice pricing has two parts. First, a participants plan sized to the number of participants you expect, booked as a day plan or a subscription. Second, optional AI Voice Translation, billed per minute per language. If you bring human interpreters, they're sourced and paid separately from the platform. Because there's no charge per event, you can set up and rehearse as many events as you like before the real one.

Compared with a traditional receiver-and-transmitter rental, the smartphone approach removes the biggest line items entirely: the receivers, the transmitter, and the staff time to hand them out and collect them. For current rates, see the pricing and AI pricing pages.

Common problems and quick fixes

Most issues come down to audio input or network connection. Here's how to handle the common ones.

No sound at all

Almost always the source connection. Check that your audio device is still selected in the dashboard and that the level meter moves when someone speaks. If the meter is flat, reconnect the cable or headset; if it moves but listeners hear nothing, have them confirm they've picked a language and pressed play.

Poor sound

Make sure the audio input is set correctly. If the audio input is set for example to the internal computer mic it will pic up a lot of background noise.

Some participants can't connect

Usual causes and fixes:

Ready to make your event multilingual?

The biggest shift for starters is realizing how little stands between you and a multilingual event: a good microphone, a stable connection for your interpreters, and a link for your audience. Nothing to ship, nothing to collect at the end of the night. The most advanced piece of equipment in the room is already in everyone's pocket.

You can run all of this yourself, or lean on LiveVoice's support services if you'd like a hand. Either way, start with a free test event and rehearse the whole flow before the day.
