Live translation.
Buy, rent or connect your existing tour system. IHOS adds live translation so guests hear the same tour in their language.

How the group hears you
The guide speaks
One live commentary, in the guide’s language.
IHOS translates live
The IHOS hub routes each translated audio feed.
One language per channel
A separate transmitter and channel carry each selected language.
Guests hear on receivers
Receivers are set to the guest’s language channel.
Phones can join, too
From IHOS, audio can also reach guests through a QR link in their phone browser. Plan receivers, phones or a mix for the same group.
Plan a mixed groupWhere internet is needed
The guide and IHOS hub need internet for cloud translation. Receiver listeners need neither a phone nor mobile data. Guests listening in a phone browser need their own internet connection.
Translation beyond tours
Use ihos for events, workplace training and Microsoft Teams meetings.

The next chapter of the guided tour
One device.
A new way
to guide.
We’re developing an all-in-one IHOS device for live tour translation. The ambition: bring a guide’s core workflow into one portable format, with more attention on the people and places around them.
Concept render. Final design and specifications may change.

Tour questions
Do guests need to download an app?
No. Guests scan the tour QR code and listen in their phone browser. Only the guide uses the ihos app.
What does each guest need?
A phone with an internet connection and their own earphones. If you prefer, they can listen on a dedicated tour receiver with an earpiece instead, with no phone needed.
Is there a delay?
Yes, a few seconds, much like a human simultaneous interpreter. Guests hear the same tour, a moment behind the guide's voice.
Can guests ask questions?
Yes. Guests on phones hold a button and ask in their own language; the guide hears the translation. OTG-200 and D220 also have hardware talk-back. Routing those receiver questions through ihos translation is checked separately for your setup.
Which languages are supported?
Tell us the languages you need. We will confirm the language pairs and test them with you in your setup demonstration.
Does it need an internet connection?
Yes. The interpretation runs live in the cloud, so the guide's phone needs a data connection, and so do guests listening on their phones. Guests on receivers don't, because the audio reaches them by radio from the transmitter.
Does it work with the tour receivers we already own?
The ihos Android hub sends each translated language to its own transmitter channel. Tell us which system you use so we can check it and test the full setup with you during the pilot.
Does ihos replace the guide?
No. Your guide leads the tour, tells the story and answers questions. ihos translates their speech into the group’s selected languages.
