Live translation has long been one of travel’s hardest unsolved problems: a single guide speaking to a mixed-language group, with no way to be understood by everyone at once. Vox Group, a 25-year-old guiding technology company operating in over 150 countries, has spent the past year rebuilding its AI-powered technology, Aura, to close that gap, now supporting simultaneous translation in up to 200 languages, live accessibility subtitles, and an AI companion designed to support guides rather than replace them. The update arrives as Vox celebrates its 25th Anniversary this month.
WHO IS VOX GROUP
Few outside the travel industry have heard of Vox Group, yet its technology underpins how millions of people experience a guided tour, powering cruise lines, tour operators, DMCs and destination experience partners in more than 150 countries. Founded 25 years ago on a simple radio link that let one guide be heard clearly by an entire group, the company has spent the years since expanding that idea, first into group guiding hardware, and more recently into Aura, its AI-powered guiding technology. Vox remains privately, family-led, an increasingly unusual profile among travel technology providers operating at this scale.
“Twenty-five years ago, we put a radio into a guide’s hand so that every guest could hear them,” says Elio Epifani, founder of Vox Group. “That principle has not changed. Aura begins with the guide and stays with the guide. What has changed is how much it can carry for them.”
THE TRANSLATION PROBLEM AI IS NOW SOLVING
Group tours have traditionally handled multiple languages in one of two ways: splitting visitors into separate language groups or adding a dedicated interpreter alongside the guide. Both add cost and complexity, and neither scale well for operators running mixed-nationality departures, increasingly the norm on cruise excursions and city tours. Aura’s translation library has grown from 50 to 200 languages over the past year, with live simultaneous translation now running in up to four languages at once on a single tour. Guests need no smartphone, app or download to take part, audio reaches them over the same radio infrastructure Vox has used for 25 years.
AN AI COMPANION BUILT TO SUPPORT GUIDES, NOT REPLACE THEM
Aura’s most significant update is its AI companion, a system designed to sit alongside the guide rather than in front of them. Rather than generating commentary from the open internet, it draws only on operator-approved content and verified sources, surfacing answers the moment a guest asks something unexpected, along with local context such as place names or regional sayings. It reflects a wider question the artificial intelligence sector is grappling with well beyond travel: where automation adds genuine value, and where it risks replacing the human expertise it was meant to support. Vox’s approach has been to keep the guide as the primary voice, using AI to extend what one person can reasonably be expected to know, rather than to generate the tour itself.
“One guide speaks once, and every guest receives a tour made for them in their own language, run from a single app,” says Fabio Primerano, Chief Executive Officer of Vox Group. “It gives guides more to work with and operators more to sell.”
ACCESSIBILITY BUILT IN, NOT BOLTED ON
Aura also addresses a gap much of the guiding technology on the market has overlooked. For guests who are deaf or hard of hearing, live subtitles are sent directly to their own phone as the guide speaks, letting them follow the tour in real time alongside the rest of the group rather than reading a summary afterwards. No separate equipment is issued, and no guest is visibly marked out as needing extra support, an accessibility approach built into the core product rather than offered as an add-on.
MULTIPLE CHANNELS, ONE DEPARTURE
Aura runs multiple commentary channels in parallel on a single tour, standard commentary, a historical deep dive, a children’s version, or a translated feed, so a family, a subject specialist and a first-time visitor can each follow a version suited to them without the guide repeating themselves. For operators, that means one departure can now carry visitors who would previously have needed splitting into separate language groups, with the tour adapting to each guest as it runs.
WHAT IT SIGNALS FOR AI IN TRAVEL
Aura’s evolution mirrors a pattern playing out across natural language processing applications more broadly: real-time translation and accessibility tools that once required specialist hardware or dedicated staff are increasingly built into existing infrastructure. For an industry still working out where AI adds value without eroding the human interactions travellers pay for, Vox’s approach, extending the guide rather than replacing them, offers one working answer.
