CaptionHub, the market leading multimedia localisation, subtitling and voiceover platform, announces the launch of CaptionHub Live – enterprise-grade, real-time AI–enabled, multilingual subtitling for live streams being used by the world’s largest companies for their flagship events.

CaptionHub Live is the UK headquartered AI tech company’s third major product launch this year, following the success of Automation — no-code, subtitling at scale — and Analytics — data insights and reporting for enterprise localisation teams.

According to CaptionHub, this new live subtitling capability is the culmination of over five years of R&D and customer feedback and has already powered live captions in keynotes and conferences for some of the world’s largest technology companies.

“In developing CaptionHub Live, we engineered solutions that resolved a number of issues that have hamstrung existing live captioning solutions – the world now has a truly resilient, no-latency multilingual live solution that underpin major flagship events” says Tom Bridges, CaptionHub’s CEO and product owner.

Existing localisation efforts for live streams are expensive and resource-intensive. Organisations can expect to pay tens of thousands of dollars for single events, with human translators hired to subtitle live events in a limited and restricted number of languages — with considerable delay.

Bridges continued: “Owing to cost, organisations have to be selective regarding which events they opt to live caption — this treats subtitle consumers almost as an afterthought. These existing subtitling solutions are reliant on old and antiquated broadcast standards, most of which do not support multilingual subtitles.”

While some existing AI-based solutions do provide live captions for streams, they intercept the stream itself, effectively making the caption provider a critical failure point in the stream path. This is often unacceptable for multiple reasons.

“CaptionHub Live solves all of these problems. Our patent-pending technology provides a level of cost-efficiency enabling our customers to subtitle more events, promoting wider accessibility and multilingual communication. CaptionHub Live provides true multilingual subtitling, fully synchronised audio, and we don’t alter the stream in any way which removes the stream risk present with other methods” adds James Jameson, CaptionHub’s Chief Commercial Officer. He goes on to say “The ultimate win for our customers is they can now broadcast their events and flagship events in 90+ languages in real-time at an absolute fraction of the cost and resource; taking their events to a global audience at the press of a button.”
