LingoCast

Visitor centers, heritage sites, museums, sound-and-light shows, guidance and advertising screens.

Your screens will speak to every visitor, in their language, on their phone.

No app, and no listening devices to look after. Visitors scan a QR from the screen, pick a language, and listen on their phone in full sync with the screening, with word-by-word captions. You set the volume that comes out of the phones, so even a visitor without headphones disturbs nobody.

This is a real, isolated demo environment of the product: starting a show here never disturbs a real screening.

How it works

Scan, and hear it right away

Step 1

Scan

Every display carries a permanent QR code. Visitors scan it with their camera and enter straight from the browser, no app and no signup.

Step 2

Pick a language

The selection screen lists every language of the display, including an audio description option for blind and low-vision visitors.

Step 3

Listen

The audio plays on the phone in perfect sync with the shared screen, with word-by-word captions and fine-tuning for wireless earbuds.

Per-display setup

Full control of every screen

You choose whether to project captions on the screen and in which language, whether to show the QR during the screening, and whether to play the audio out loud and in which language. For example, a sound-and-light show the whole hall hears in Hebrew, while tourists get their own language on their phone, separately.

Visitors scan to join straight from the screen. Turn it off for a clean screen with separate QR signage.

Captions projected to the whole hall, on top of the personal captions on each phone.

Play a dominant language through the projector, alongside the personal multilingual audio on phones.

Each visitor's personal phone captions and audio are always on, in any language. These settings only control what happens on the shared screen and in the hall.

Who it's for

Anywhere one screen meets a multilingual audience

Museums and exhibitions

Looping or on-demand exhibit films in every hall. Each visitor listens in their own language, no costly guide devices.

Shows and attractions

A multimedia experience or a timed show with an operator: the whole audience starts together on a shared countdown.

Heritage and memorial sites

A sensitive story told to every visitor personally and in their language, with built-in audio description.

Visitor centers and organizations

Orientation and brand films that speak to international guests exactly as they do to the local audience, even when one group speaks several languages.

The advantages

Why LingoCast

One system that replaces audio guide devices, translation booths and separate accessibility solutions.

No app

Browser only. One scan and the visitor is in, on iPhone and Android alike.

Precise sync with the screen

A shared clock keeps every phone at the exact same point of the screening, with fine-tuning for wireless earbuds.

Word-by-word captions

Text highlights word by word at the pace of the narration, in every language, including right-to-left scripts.

Any language you want

Add languages without a ceiling: narration, captions and audio description per language.

Built-in audio description

An audio description track for blind and low-vision visitors sits in the same selection screen, as an equal option among the languages.

Three screening modes

A continuous loop for exhibit halls, on-demand start from a visitor's scan, or a live show run by an operator.

No dedicated hardware

An existing screen plus the visitors' own phones. Nothing to rent, sanitize or maintain.

Fully self-managed

A simple CMS: upload video and narration, get a print-ready QR code, update anytime.

Built for crowds

Made for large groups arriving together: the screening stays in sync even as dozens of phones join at once.

Can start on its own, with no operator

The hall’s control system announces that the screening has begun and the audio joins in sync. Suits a sound and light show, a visitor-centre presentation and a looping film.

The hall stays quiet

The first worry is a whole hall playing out of phone speakers. You set the volume that comes out of them, and that is what everyone gets: low enough to hear with the phone at your ear, not enough for the person beside you. Anyone who brought headphones switches to full volume and disturbs nobody anyway.

We work with your equipment

A screen on a wall, an installation, or mapping onto a mountain

We do not touch your equipment and we do not replace it. All we need is one signal the moment the screening starts, and the system already running it knows how to send one.

  1. The screening starts as it always does

    From whatever already runs it today: a controller, a media server, a player, a timer, or a guide pressing play.

  2. We are told at that moment

    And we work out the exact point in the screening, including the time the projector takes to show a picture.

  3. The audio starts on the phones

    Every visitor in their own language, in sync with the screen, including anyone who walks in late.

A one-off connection, usually under an hour.
Your AV person does it. Haven’t got one? We guide it remotely.
Nothing in the hall is replaced or added.
What your AV person needs to knowTechnical detail. Feel free to skip it and pass it on.

One line in the control program

That is the whole scope. A short string, once, the moment the projector is told to play. We supply a ready specification with the address, the port and the string for each hall.

The protocols a control system can send the trigger over
UDPThe most common on control systems
TCPA string with a line ending
HTTPA plain GET, with no extra equipment
MASADA_START\n

That is the entire string, exactly as it appears in the specification you receive.

Systems that work with us

These three come with a ready code snippet in the specification, matched to your hall.

  • CrestronSIMPL · TCP/IP or UDP/IP Client
  • Q-SYSLua · TcpSocket / UdpSocket
  • BrightSignBrightAuthor:connected · Send TCP / UDP

And any other system that can send a string over the network or open a URL: Extron, AMX, Medialon, media servers such as Watchout, disguise and Resolume, media players, or a custom system.

The Spotix Gateway: when the control network stays closedSome sites keep the control network closed as a security policy, some controllers can send a string on the network but cannot open a URL, and some venues simply do not want a screening to depend on a connection. The Spotix Gateway answers all three: a small fanless computer in the comms rack that listens for the trigger inside the AV network and passes it to us. Your network is never opened outward.
Accessibility

Accessibility isn't an add-on. It's the core.

LingoCast exists so every visitor experiences the same screening in full. Making a screening accessible is built into the product, designed to the WCAG 2.0 level AA guidelines and the IS 5568 standard, and verified on real devices.

FAQ

Questions and answers

What is LingoCast?

LingoCast is a Spotix system that streams audio and word-by-word captions to each visitor's phone, in their own language, in full sync with a shared screen in the hall. It runs entirely in the browser: visitors scan a QR code, pick a language and listen. No app, no signup, no rented audio devices.

How does the audio on the phone stay in sync with the video on the screen?

Every phone and the screen align to a shared cloud clock, so all of them sit at the exact same point of the screening. A visitor who joins mid-show lands at precisely the right moment, and anyone listening on wireless earbuds can fine-tune the sync while watching.

Do visitors need to download an app or sign up?

No. LingoCast works in the browser of any modern phone, on iPhone and Android. Visitors scan the QR code on the display, choose a language and listen. There is no installation, no signup and no collection of personal details, which is what lets large groups join within seconds.

How does LingoCast make screenings accessible to visitors with disabilities?

The system includes audio description tracks for blind and low-vision visitors, word-by-word captions for deaf and hard-of-hearing visitors, full screen reader support with VoiceOver and TalkBack, high contrast and respect for reduced-motion preferences. Accessibility is verified on real devices and is part of the product core, not an add-on.

Which screening modes are available?

Three modes: a continuous loop for exhibition halls that runs all day, on-demand playback that starts when a visitor scans the code, and a live show with a shared countdown for the whole audience. The live show can be driven two ways: an operator controlling start, pause and hall language from their phone, or the venue’s own control system telling us the moment the projector starts, with no staff in the hall.

What do we need to deploy LingoCast at our venue?

An existing screen or projector with a browser, your video and narration files, and an internet connection. You upload the content to the management system and get a QR code ready to print for each display. If the hall has a control system that starts the projector, it can be connected to us with one line in its program, and we supply a ready specification for the integrator.

Can I customize what each display shows on the screen?

Yes. Every display is configured independently in the CMS: show or hide the QR code on the screen, turn on captions projected to the whole hall, and play a dominant language through the projector speakers. Each visitor's personal phone audio and captions always work, in any language, regardless of the screen settings.

Is there a limit on the number of languages in LingoCast?

There is no limit. You can add as many languages as you need, and each language gets its own narration, word-by-word captions, and an optional audio description track. Visitors pick their language from the selection screen on their phone.

Can a visitor switch language in the middle of a screening?

Yes. At any moment a visitor can open the language menu on their phone and switch to another language, including an audio description track, and the audio and captions continue from the same point in the screening without losing sync.

Is LingoCast accessible and built to WCAG 2.0 AA?

LingoCast is built to the WCAG 2.0 level AA guidelines and the IS 5568 standard: audio description, word-by-word captions, high contrast, screen reader support, and respect for reduced-motion preferences. We tested it with VoiceOver and TalkBack on real devices and with automated accessibility tools with no errors. Testing was done by our team, not by an external certified accessibility auditor.

How does LingoCast solve the mixed-language group problem in visitor centers?

In visitor centers and tourist sites a single group usually mixes speakers of different languages, and without a solution you must pick one language, split the group, or lose some visitors. LingoCast lets the whole group watch the same screening together, each hearing and reading in their own language on their own phone, fully in sync with the shared screen. International guests get exactly the same experience as the local audience.

Our hall runs with no staff. Can LingoCast start on its own?

Yes. If your screening is started by a control system, a timer or a guide, that system tells LingoCast the screening has begun and the audio on the phones starts in sync. Nobody has to touch anything. It suits a sound and light show, a visitor-centre presentation and a looping orientation film. The connection is one line in the control program, done once, with no equipment replaced in the hall. We send your AV person a ready specification, and we support UDP, TCP and a plain HTTP call.

Forty phones in a dark hall. Won’t that be noisy?

No, because the volume is yours to set. When you manage the screening you set the volume that comes out of the phones in the hall, and that is what every visitor gets. It is low enough that the visitor holds the phone to their ear and the person beside them hears nothing. We tested it on a new iPhone and an old Android: the narration is clear at the ear and does not reach the next seat, even at maximum device volume. A visitor with headphones can switch to full volume and set it to their own taste, because on headphones they disturb nobody anyway. All of this is in addition to the option of playing a dominant language through the hall speakers.
