Washington, D.C. — CaptionHub, the market-leading video and audio captioning platform, was selected as the captioning partner for the 2020 NAB Show Express. NAB Show Express used CaptionHub’s AI technology to deliver event video captioning at an unprecedented scale as it shifted event education and exhibitor profiles to an entirely online offering.

NAB Show provided session captioning for the deaf and hard of hearing, underscoring the event’s commitment to accessibility for all. CaptionHub has developed a proprietary AI model called Natural Captions©, which pairs advanced speech recognition with natural language processing and scene detection. The result is naturalistic, readable captions.

Using CaptionHub’s integrated machine translation, key sessions were translated, furthering NAB Show’s reach and enabling transmission to a global audience.  The success of NAB Show Express paves the way for future online events as trade shows expand their digital presence.

“CaptionHub was selected for its ability to deliver captions and subtitles at the scale needed by NAB,” said Dorian Sullivan, vice president, Audience Development. “Leveraging its existing integration with online video platform partner Brightcove, CaptionHub provided a simple, effective route for NAB to ingest and publish subtitles.”

“Post production is in CaptionHub’s DNA, so we were delighted to be approached by NAB. It is the benchmark event for the media industry,” said Tom Bridges, CaptionHub’s founder and CEO. “They also share our values around accessibility and making content available for the widest possible audience. Our technology helps power captioning for some of the world’s biggest brands, but it’s the human connection that we feel most passionate about.”
