When Responsible AI goes live on stage and plain X gives everyone a voice

Yesterday at the Champalimaud Foundation, the Center for Responsible AI showed something very clear: responsible AI is no longer a slide in a presentation, it’s a set of concrete solutions already changing how we live, work and receive care. And we were proud that plain X Live (captions & voice-over) was part of that story.

Throughout the event, plain X Live was used to make every talk and panel accessible in multiple languages, in real time. Participants simply opened a link on their phones, chose their preferred language, and decided whether they wanted live subtitles or live voice-over. No app install, no friction, just “reach everyone, in every language, as it happens.”

Behind the scenes, the operator cockpit allowed the team to tune latency, pick the best engines per language (Whisper, Google, Azure, Deepgram, Speechmatics, etc.), and load domain glossaries so names, acronyms and medical terms came through correctly. Our low-latency pipelines kept captions under ~2 seconds, while the mobile app let people adjust subtitle size or listen via high-quality audio, often with headphones.

While we focused on inclusion and accessibility, the stage was full of powerful responsible AI use cases:

  • Sword Health and its AI-powered telerehab, cutting physical therapy waiting times by 93%.
  • Halo (Unbabel), helping people with conditions like ALS recover their voice.
  • Priberam Care, improving how doctors and patients communicate during consultations.
  • Visor.ai, automating 99% of vaccine bookings in a pharmacy chain.
  • Automaise x Continente, handling 95% of back-to-school support requests in retail.
  • Affine (NeuralShift), saving 6–8 hours per week in legal research.
  • YooniK RID / Youverse, making check-ins 20% faster across 30 Pestana Group hotels.

Events like this remind us that responsible AI is about more than models and metrics. It’s about who gets to follow the conversation, participate and be heard.

Yesterday, at the Champalimaud Foundation, plain X Live helped make sure no one was left out.

If you’re running webinars, conferences or hybrid events and want live captions and multilingual voice-over that people actually use, we’d love to talk.
