The Global Tech Summit in San Francisco had the same old problem in early 2026. How do you get a global audience to actually connect when most of them don’t speak the same language? People would tune out of fast-paced talks, avoid the Q&A, and stick to their own language groups during breaks. Interprefy’s AI translation, built for mobile event tech, looked like a real solution, a way to get live audio feeds in dozens of languages directly onto attendees’ own phones.
Key Takeaways
- Putting AI-powered real-time translation tools right into an event’s mobile app makes it possible to support many languages, sometimes up to 20 at once.
- For the most important sessions or high-stakes presentations, bringing in human interpreters ensures you get the accuracy and nuance that AI alone can miss.
- Translating materials like the agenda, speaker bios, and logistical info before the event starts is a simple way to reduce confusion for international attendees on-site.
- Event staff need to be trained on how the mobile translation actually works so they can give immediate support and fix common user problems.
- To know if the translation services are actually effective, it’s important to measure engagement metrics like session attendance and specific feedback on language access from post-event surveys.
Why Language Barriers Were Tanking Engagement
For years, big events like the Global Tech Summit had to rely on old-school simultaneous interpretation. That meant huge booths lining the back of ballrooms, a frantic scramble to distribute and collect headsets, and an insane amount of logistical overhead. The cost for just a couple of the most common languages could eat up a huge slice of the budget, which meant anyone speaking a less common language was out of luck. They felt cut off, couldn’t really follow the Q&A sessions, and had a much harder time networking or catching the subtleties of a keynote speech.
Take Dr. Anya Sharma, a top AI ethics researcher from Bengaluru who attended the 2025 Summit. Her native language is Hindi. While she’s proficient in English, she found herself struggling to keep up with the rapid-fire technical arguments and the casual jokes during networking. She was missing key points and felt hesitant to ask a question in English. In the end, she felt more like an outsider than a participant. This wasn’t a one-off story. Post-event surveys were full of comments like “I couldn’t follow the keynote” or “I wish there was a session in my language,” showing a clear pattern, especially from attendees in growing tech markets.
The organizing committee, headed by Operations Director Mark Chen, saw this as a massive failure. “We wanted to attract the best minds globally, but if they couldn’t understand or be understood, we were failing,” Chen told Reuters in an interview after the event. The traditional setup, hiring teams of interpreters and renting booth equipment for every single language, wasn’t a scalable or affordable model for an event that truly wanted global reach.
The Hunt for a Modern Fix
Mark’s team started looking for alternatives in late 2025. They had a clear checklist: whatever they chose had to plug into the event mobile app everyone was already using. It needed to handle a whole lot of languages. And it had to be dead simple for thousands of people, many of whom weren’t tech-savvy, to figure out. The market was full of new AI translation tools, but most were for one-on-one chats and couldn’t handle the complexity of a huge conference with multiple speakers. Above all, it had to work. A glitchy translation that cuts out is more distracting than no translation at all.
Their search led them to Interprefy, a company that specializes in remote interpretation and AI translation for events. The thing that really got their attention was Interprefy’s hybrid model. It meant they could use certified, professional human interpreters for the must-be-perfect main stage keynotes, streaming that high-quality audio directly to attendees’ phones. Then, for all the smaller breakout sessions and networking events, they could use the AI translation engine to provide instant, if occasionally less perfect, interpretation.
Making it work inside their existing mobile app was a deal-breaker. Attendees already had the app for their schedules, maps, and speaker bios. Forcing them to download a second app or deal with a complicated setup was a non-starter. “We needed it to be as simple as tapping an icon and selecting a language,” Chen explained. He knew any extra friction would mean people just wouldn’t use it.
“On this episode of TechCrunch’s Equity podcast, Rebecca Bellan is joined by Connor Leahy, an AI researcher, entrepreneur, and now the U.S. Executive Director of nonprofit ControlAI, which is pushing for a far more radical approach to AI safety: stopping companies from developing superintelligence altogether.”
The Rollout Strategy
For the 2026 summit, the team went with a tiered rollout. They picked 15 primary languages to receive human-powered interpretation for every main stage event and a handful of the most popular breakout sessions. Then, for another 20 languages, they enabled AI translation across all sessions. This hybrid plan let them put their budget where it mattered most, on human expertise for the biggest moments, while still giving nearly everyone a translation option.
Before the event, the team worked with Interprefy to get the tech integrated. This involved setting up API calls to pull live audio from each session room and then push the translated audio back to the app in real time. They didn’t just hope for the best. They ran weeks of tests with a beta group to hunt down latency problems, audio bugs, and confusing parts of the user interface. One of the biggest takeaways from testing was the need for super-clear, in-app instructions (with pictures!) on how to pick a language and what to do if it wasn’t working, so they built a quick tutorial that popped up the first time anyone used the feature.
At the summit, it was straightforward. An attendee opened the app, found the session they were in, and tapped a “Language” icon. From a dropdown menu, Dr. Sharma, for instance, could select Hindi. The AI system, which ran on advanced neural machine translation models, took the speaker’s English and delivered a synthesized Hindi voice to her headphones almost instantly. For the big opening keynote, she just switched over to the human interpreter’s channel to get that completely fluent, natural delivery.
It wasn’t perfect from the start. On day one, the Wi-Fi in one of the big ballrooms got swamped, which caused some brief audio dropouts for people using the AI translation. The on-site support team, who had been trained by Interprefy beforehand, quickly figured out what was happening and worked with the venue’s IT staff to reconfigure the Wi-Fi channels. It was a good lesson: even with amazing tech, you still need solid infrastructure and smart people on the ground to fix things when they break.
The Results: More Than Just Words
The difference was obvious. Dr. Sharma said her experience was night and day compared to the year before. “I could follow every presentation without mental strain,” she shared. “More importantly, I felt confident enough to ask questions in my own language during a Q&A, knowing the speaker would receive a clear translation.” That confidence meant she was actually participating, not just sitting there. Being able to follow networking chats, even with the slight delay of the AI, let her join conversations instead of just standing on the sidelines.
The numbers from the Global Tech Summit committee backed this up. Post-event surveys showed a 35% increase in satisfaction scores related to language accessibility from the previous year. The total number of questions asked in Q&As went up by 20%, with most of that growth coming from attendees who weren’t native English speakers. As Mark Chen put it, “It helped our attendees contribute fully.” The discussions got better because you were hearing from people who would have stayed silent before. During one panel, for instance, a question from an attendee listening in Korean sparked a whole new direction in the on-stage debate. A 2025 report by the Event Industry Council confirms this, finding that accessibility features like translation directly link to higher attendee satisfaction and retention.
The hybrid approach was definitely the right call. For the opening keynote by Dr. Evelyn Reed, a Nobel laureate from Sweden, the human interpreter delivered a flawless translation of her complex message. But later that day, in a small, technical breakout on quantum computing, the AI translation let a diverse group of researchers debate theories in their preferred languages, fostering a conversation that would have been impossible with a single language barrier.
Lessons Learned and What’s Next
So, what’s the takeaway from the Global Tech Summit’s experience with Interprefy’s AI translation for other event organizers? First, the hybrid human-AI model gives you the best of both worlds. You get accuracy where it counts and broad coverage everywhere else, all at a manageable cost. Relying only on AI can lead to misinterpretations with highly technical or culturally sensitive topics, while using only human interpreters is just too expensive if you want to support a lot of languages.
Second, the tech has to be integrated directly into your existing event app, because asking attendees to download and learn a separate program is a surefire way to kill adoption. Third, you can’t cheap out on network infrastructure and on-site support. AI translation needs stable internet and clean audio streaming to function properly, and you need people on hand who can solve problems fast. And finally, you have to tell attendees the feature exists and show them how it works. If they don’t know about it or can’t figure it out in seconds, it might as well not be there.
Looking ahead, Mark Chen’s team plans to add even more languages supported by human interpreters for their main sessions. They’re also looking into how AI could be used for real-time transcription and summary generation in multiple languages, making event content useful long after the conference ends. For any event that’s serious about being global, this kind of AI-powered translation is quickly becoming a must-have tool.
What is AI translation in mobile event tech?
It’s technology that uses artificial intelligence to provide real-time language translation services directly inside an event’s mobile app. This lets attendees listen to talks and presentations in their preferred language using their own phone and headphones.
How does AI translation differ from traditional simultaneous interpretation?
Traditional interpretation uses human interpreters in soundproof booths who translate live. AI translation uses machine learning algorithms to do the job, which typically means you can offer far more languages for less money, though it can sometimes miss the nuance a human interpreter would catch.
What are the benefits of using Interprefy for mobile event translation?
Interprefy’s main advantage is its hybrid model that mixes human and AI translation, giving you flexibility. It plugs into existing event apps, supports a huge number of languages, and streams the translated audio right to an attendee’s phone, which makes the event more accessible and engaging for everyone.
Can AI translation handle highly technical or specialized content?
AI has gotten much better, but it can still struggle with very specific technical jargon or culturally nuanced topics. For that kind of content, using a hybrid approach with human interpreters for the most critical sessions is usually the safest and most effective strategy.
What should event organizers consider when implementing AI translation?
Organizers need to think about their budget, how many languages they need to support, and how accurate the translation needs to be for different types of sessions. They also have to make sure their venue’s Wi-Fi can handle the load and that the translation tech works smoothly within their main event app. Doing a lot of testing beforehand and having tech support on-site is also key.
