No Receivers, No Problem: How to Run Guided Tours from Your Smartphone

For most of the history of guided tours, getting your voice to a group of twenty people meant hardware. A tour guide system with a transmitter on your belt, a receiver in every guest's hand, and a case full of units to charge, distribute, and collect at the end. That system still works. It's also expensive to buy and a logistical challenge every time you run a tour.

In the last few years, a different approach has changed the way it's been done before: tour guides using the smartphones their guests already carry as the receivers. The guide speaks into their phone, guests listen on theirs, and the audio travels over the internet in real time. Tools like LiveVoice are built specifically for this, letting guides run an audio guide system entirely through an app, without any additional hardware.

How a smartphone audio guide system works

The guide speaks into their phone, and the audio streams live over the internet to everyone in the group. Guests listen through the app on their own phones, with no dedicated receiver required.

With LiveVoice, a guide creates an event in advance, which takes a few minutes. When the tour starts, they open it and begin streaming. Guests join using a QR code, a link, or a short invite code shared at the meeting point, and from there the audio runs in the background so they can take photos or lock their screen without losing the audio.

How guests listen

Most guests listen with their own earbuds or headphones. Anyone who forgot theirs can hold the phone to their ear, the way they would for a phone call. Or, the guide can provide a handful of one-way earbuds and adapters (as most phones don't have standard audio jacks anymore) for the guests who didn't bring theirs.

As for the delay: it's small enough that guests won't notice it. Live audio through LiveVoice has an average latency of 0.2 seconds, which is effectively real time. It can vary slightly depending on the device, but even older phones stay close to that. When you point at a building and say "on your left," your guests hear it as you're pointing.

Your microphone

If you already guide with a headset, you know the rules: mic close to the mouth, one ear left open so you can hear your group and the traffic. None of that changes when the receiver is a phone.

What does change is the connection. Your headset plugs into your phone instead of a transmitter, so if it has a 3.5mm jack and your phone doesn't, you'll need an adapter. On iPhones it's worth using the original Apple one, since some third-party adapters handle listening but not microphone input.

If you're starting without a headset, a single-ear model is the one to get. LiveVoice recommends a Jabra for guided tours. Standard smartphone headphones or AirPods work too, they just pick up more background noise because the mic sits further from your mouth.

If you interview people on your tours, a handheld mic is worth having. There aren't many handhelds made for smartphones, so the usual workaround is a clip-on mic (a 4-pole one, made for phones) attached to a handheld adapter. You pass it to whoever's speaking, and your group hears them properly instead of straining to hear.

Testing before your first tour

Walk your route once before you guide it for real. Just so you know if the signal drops on your own route, especially in more remote areas.

The app tells you when something goes wrong. While you're streaming, the speaker interface is orange. If your connection drops, it turns gray, so you know the audio has stopped streaming due to connection issues. Then you can plan your talking points around the weak spots.

Battery on a long tour

While the LiveVoice app does not use a lot of energy, streaming for four hours still uses battery, so ideally start fully charged and carry a powerbank. That's your side covered.

Your guests are less predictable, so some operators keep a couple of small powerbanks in their bag in case a guest has not come well prepared.

A line in your booking confirmation asking guests to arrive with a charged phone and their own earbuds prevents most of it.

What the tour guide needs

The guide streams from their own smartphone over Wi-Fi or mobile data (3G, 4G, or 5G). There's no transmitter, no base station, and no extra device to keep charged. Audio uses very little data: LiveVoice uses roughly 120 times less than YouTube, so streaming doesn't meaningfully eat into a standard mobile plan, even if you run tours every day. And if your own plan doesn't cover you where you're guiding, you can connect to the same mobile Wi-Fi router you might bring for your guests.

What guests need: mobile data, Wi-Fi, and planning for tourists

Depending on your guests, you have different options. If they all have mobile data, you are all set and don't need anything else.

If they don't have their own mobile data, for example because they come from another country and have not installed a local eSim, the most reliable solution is to bring a mobile Wi-Fi router and provide the connection yourself. You switch it on at the meeting point, guests connect, and the question is settled before the tour begins.

The router's capacity is worth planning around. Mobile routers usually have a limit of how many devices can connect at the same time, so check for that when buying one. Guests using their own mobile data don't count towards it, so a mixed group often works out fine in practice. For larger groups where you're providing the connection for everyone, choose the router accordingly.

A router also helps on tours in areas with weak signal, such as remote sites, old buildings, or outdoor routes away from town centres. It won't solve a complete dead zone, but it handles most real conditions reliably.

What changes depending on the kind of tour

The setup is the same everywhere, but a few things shift depending on where you guide.

Walking tours in cities are the easiest case. Mobile coverage is usually good, and the main gain is that your group can spread out at a crossing or stop for a photo without missing what you're saying.

Museums and indoor venues often have house Wi-Fi you can use, however we usually recommend to turn off the Wi-Fi of the devices, using mobile data instead. The reason: When walking from room to room, phones have to switch from Wi-Fi router to Wi-Fi router; in the moment of the switch, connection might be lost of the beat of a second which can lead to a short interruption of the real time audio.

Bus tours work well because everyone's stationary and close by, and there's no passing a microphone down the aisle. If you guide from the front while people sit at the back, a headset is especially important.

Boats, rural routes, and remote sites are where the mobile router earns its place. Coverage is the variable you have least control over, so bring your own connection rather than hoping.

Making tours multilingual with AI

Most guides running smartphone audio tours do so in a single language. But the same setup also makes multilingual guiding possible without a second system or an additional guide. With LiveVoice, AI Voice Translation can be added to any tour in over 70 languages. Guests choose their language and hear the audio translated in real time.

In this way, guides can easily expand their reach. Only one guide is necessary even if the guests come from different nationalities.

Live Captions for guests who are hard of hearing

A lot of guides don't realise this is possible: LiveVoice can show a live transcript of what you're saying, in the same language you're speaking or translated. Someone who struggles to follow spoken audio can read along as well. Audio going directly into their earbuds already helps compared to listening across a noisy room, and the live transcript covers the rest.
