Real-Time Interpretation Solutions Comparison (2026): EventCAT, Flitto Live vs. Hudson Live
An objective look at the published specs of the three most-compared AI real-time interpretation solutions of 2026, and how the technical gap between "text subtitles" and "voice dubbing" should drive which one you pick.
- AI interpretation has become the default at large events, and the number of solutions has exploded — but from a planner's seat, specs alone rarely tell you which one fits your event.
- They all look like the same "real-time translation" from the outside. On the floor, though, a text-first (subtitle) product and a premium-voice (live dubbing) product serve completely different purposes.
- This article takes apart the technical differences between the three solutions most often compared in 2026 — EventCAT, Flitto Live, and Hudson Live — and gives you a clear basis for choosing by event purpose.
Once you have decided to drop the booths and receivers in favor of AI real-time interpretation, the next task is picking the solution. Every leading product on the market today supports both text (subtitles) and voice (TTS) as table stakes. But there is a pronounced technical gap in what attendees actually experience: the quality and immersion of the audio.
Will it stop at putting translated words on a screen and reading them out in a robotic tone — or will it filter out room noise and deliver broadcast-grade dubbing that carries the speaker's emotion and intonation? Planners should draw that line deliberately, session by session, based on how much each one matters.
This article dissects the core capabilities and limits of the three solutions most discussed in the global multilingual event and conference market — EventCAT, Flitto Live, and Hudson Live — based on the specs published on each company's official website.

📱 1. EventCAT: unmatched compatibility and easy access
EventCAT's motto is interpretation anyone can reach. Per its official website it delivers 50+ languages as real-time subtitles and voice (TTS), and its biggest strength is operational convenience and freedom from hardware constraints.
- Mobile access via QR/URL: attendees see and hear the interpretation on their own phone by scanning the QR code on the venue screen or clicking a URL — no app install.
- Full video-conferencing compatibility: it can be invited as a bot into Zoom, Google Meet, or MS Teams to feed live subtitles and audio into the platform you already use, which makes it strong for hybrid meetings.
- Security and customization: SOC2 certified for enterprise data protection, with a glossary feature for industry-specific terminology.
💡 Deployment tip: the most cost-effective and frictionless choice for track sessions running simultaneously across several small rooms, or internal global town halls where the point is simply getting the information across.
🦋 2. Flitto Live: the translation accuracy that dominates academic conferences
Flitto is a well-established global language data platform. Flitto Live, its real-time interpretation solution, supports 38 languages and 120+ language pairs, and stands out specifically on data-driven translation accuracy.
- Quality tuned for specialist fields: it delivers high-quality translated text and voice (TTS) at global academic conferences dense with medical, IT, or legal terminology, lowering the barrier between speaker and audience.
- A large-corpus engine: because the engine runs on the high-quality language data Flitto has built over years, the awkward literal-translation errors typical of machine translation are markedly rarer.
💡 Deployment tip: the right fit when the credibility of the text decides the quality of the event — pharma/bio symposia or researcher-facing seminars where academic and technical fact-checking comes first.
🎙️ 3. Hudson Live: past machine voice, into broadcast-grade live dubbing
Where EventCAT and Flitto Live provide excellent text-first read-aloud, Hudson Live is a high-end solution that moves the paradigm of event interpretation up a level, to a natural premium audio experience. Per the Hudson AI website, Hudson LIVE goes beyond interpretation and translation as the culmination of its AI-powered audio intelligence technology.
- Real-time Audio Separation: a large venue mixes background music, echo, and audience murmur in with the speaker, which badly degrades speech recognition (STT) accuracy. Hudson Live separates music from vocals — the speaker's voice — cleanly and in real time, establishing a far stronger audio baseline.
- Premium AI live dubbing: this is not the flat navigation-system tone of ordinary TTS. Hyper-realistic text-to-speech reproduces the original speaker's breathing, emotional expression, and intonation in the dubbed multilingual audio, which keeps the audience immersed.
- Seamless broadcast integration: it integrates cleanly with existing broadcast systems and accepts professional live streaming inputs including HLS, SRT, and RTMP. For large online events going out to YouTube or global distribution platforms, you get audio separation, translation, and live dubbing in a delay-free broadcast pipeline.
💡 Deployment tip: for the main events where an audiovisual brand experience and broadcast-grade sound are non-negotiable — a main-stage keynote with global VIPs, a product unpacking streamed live worldwide — Hudson Live is the only answer.
❓ Frequently asked questions
Q. EventCAT and Flitto Live also let you listen to audio. What is actually different about Hudson Live?
A. All three let attendees listen through earbuds. The difference is the depth of the audio. With EventCAT and Flitto Live, the voice is closer to a supporting layer (basic TTS) that reads the translated subtitles faithfully in a standard AI voice. Hudson Live is built for live dubbing — removing background noise and layering the speaker's emotion and intonation back on — which produces a large gap in listening fatigue and immersion over a long session.
Q. Our venue is an open space like KINTEX or COEX with heavy ambient noise. Will interpretation hold up?
A. On an open stage where white noise and microphones from neighboring booths bleed in, mic pickup and noise filtering decide translation quality. This is exactly where Hudson Live's Audio Separation — precisely targeting and extracting only the human vocal from the audio track — becomes the strongest defense against mistranslation.
Q. Can it connect directly to our global live streaming (YouTube, etc.) equipment?
A. Hudson Live Studio is designed to integrate seamlessly with existing broadcast systems. It accepts HLS, SRT, and RTMP live streaming input directly, so it drops into a broadcast-grade pipeline with no complex conversion step and no additional hardware.
🔜 Next step: build a session-by-session two-track strategy
If you are planning a large conference that has to be both successful and budget-efficient, splitting the solution is the 2026 answer. Put EventCAT or Flitto Live, with their strong mobile access, on the casual breakout sessions that run in parallel for large numbers of attendees.
And for the sessions that are the face of the event — the main keynote and the global live-stream stage — bring in Hudson Live, which gives the audience overwhelming immersion and a natural live dubbing experience. More detailed consulting for your event's scale and streaming setup is available through the official site.
