Automated Captioning for Radio

Radio broadcasters can benefit from where Television broadcasters have been for decades, by using ENCO's enCaption to automatically caption & transcribe your verbal content - not to video, but to your website, streaming endpoint displays and various digital platforms, all while creating text transcripts of every word said on the air.

How do you make radio news more accessible?

News & talk radio has long had a challenge - how to communicate with members of the deaf and hard-of hearing-communities. Radio broadcasters can now effectively address their audiences!

enCaption for Radio

Our automated AI-based, advanced Automatic Speech Recognition system generates text captions of every word said on the air, making those captions available for your Website, RDS transmissions, stations Apps, even large display screens. It’s fast and accurate, and totally on-premise (no Internet needed).

“ENCO is a leader in live captioning and is doing this better in real time in a fully automated way than any other solution we have come across.”

- Rob Bertrand
Senior Director of Technology WAMU

Live On-Air Captions

enCaption ingests the on-air signal path being routed to WAMU’s transmitter and online streaming encoders, enabling live, 24/7 captioning of all of WAMU’s on-air content. The captions created by enCaption are then fed to the station’s website, where they are displayed in a dedicated transcription page.
Generate text transcripts from your legacy audio recordings with ease, making them more accessible both in-house to your writers & editors, as well as your online audience. This is because the latest generation can optionally caption both Live and File-based assets with ease.
