You speak into your phone. Guests scan a QR code and listen to the translation in their own headphones, on their own phones.
Your link is in your driver app — the 🎧 Tlmočenie (Translation) button. It is yours alone, and what it spends shows up under your name. Do not pass it on — not to colleagues, not to guests. It is valid for 12 hours; tap the button again in the app and you get a fresh one. If it is not there, call +421 910 212 212.
While ON AIR is showing, it is costing money. You pay for every minute of every started language — not per guest. One hour of one language costs about €1.75.
Always tap Stop at the end of the tour. Do not count on closing the browser to do it for you.
In the driver app tap 🎧 Tlmočenie. The translator page opens. Do not bookmark it — the link expires after a few hours.
Under Guest languages. One is usually enough. Every extra language costs money and loads the phone — do not tick languages just in case.
The phone asks for microphone access. You must allow it, or nothing starts.
When all is well, ON AIR shows in large letters, with a language row saying live underneath.
It is on the screen from the start, even before Start. The guest scans it with the camera, taps Listen and puts the headphones on.
Let them do it before you set off, while everyone is standing still. On the move nobody manages it.
Keep the phone close to you, microphone towards you. The translation arrives a few seconds behind — it is interpreting, not an echo.
Glance at the screen now and then: the language row must say live.
This is the most common reason guests suddenly hear nothing. Find your phone below.
The microphone keeps running even with the screen locked. But first turn off battery saving for the browser, or the phone will quietly kill the app after a few minutes.
Try it once at home: start the translation, lock the phone for two minutes and check on a second phone that the sound is still there.
When an iPhone locks, it switches the microphone off and the translation ends. This is not a fault in our app and we cannot fix it — it is an iPhone limitation.
On both phones: do not switch to another app while broadcasting — the translation stops and guests hear silence.
If nobody says anything for five minutes, the session ends. That is on purpose: there is no point paying for sessions running empty on the bus or after the tour.
It is not a fault. To carry on, tap Start again — exactly as at the beginning. Guests can stay on their page; if they hear nothing, have them tap Listen once more.
When you know there is a longer break coming (lunch, a transfer), just tap Stop.
Scan this code with your camera, tap Listen, and put your headphones on. Keep the page open — if you switch apps, the sound stops.Spanish
Escanea este código con la cámara, pulsa Listen y ponte los auriculares. Deja la página abierta: si cambias de aplicación, el sonido se corta.German
Scannen Sie diesen Code mit der Kamera, tippen Sie auf Listen und setzen Sie Ihre Kopfhörer auf. Lassen Sie die Seite offen — wenn Sie die App wechseln, hört der Ton auf.
| What you see | What to do |
|---|---|
| The translation switched itself off | There were five minutes of silence. Tap Start again. It is not a fault. |
| The link says it is invalid or expired | The link lasts 12 hours. Go back to the driver app and tap 🎧 Tlmočenie — you get a new one. |
| The guest hears nothing | First: Settings → Broadcast to guest phones must be ticked. If it is not, the QR still shows and the guest still joins, but hears nothing. Then have them tap Listen once more — a browser only plays sound after a tap. Last, check that the language row says live. |
| A guest lost the sound mid-tour | They switched apps or locked an iPhone. Have them open the listening page and tap the screen. |
| You lost the sound after pocketing your phone | iPhone: set Auto-Lock → Never. Android: turn off battery saving for the browser. See the section above. |
| The QR will not scan | The same link is printed as text under the code — send it to the guest in a message. |
| Failed — microphone blocked | End your phone call first — during a call the phone will not lend out the microphone. Then allow the microphone next to the address bar, reload the page and tap Start. |
| Failed — another app is holding the microphone | Close the voice recorder, another translator app or the call, then tap Start. |
| The sound is choppy | Settings → Audio smoothing → Smooth (800 ms). The translation arrives slightly later, but in one piece. |
| It is translating from the wrong language | Settings → Guide's language → set the language you actually speak. |
| A language says cannot reconnect | Stop, then Start. Guests then have to tap Listen again. |
| Server not responding | Check your data and reload the page. If the internet works and the message stays, call +421 910 212 212. |
