GB News has signed a deal with tech firm Ai-Media allowing it to launch a 24/7 subtitling service.
The captioning uses a mixture of Automatic Speech Recognition alongside human intervention to provide an accuracy of 98.5%.
The channel launched less than 18 months ago and is not yet required to offer subtitles by Ofcom but took the step ahead of schedule following viewer feedback and a recent investment of funds which made it possible.
CEO Angelos Frangopoulos said: "As The People's Channel, it is hugely important to us to include all voices across the United Kingdom, especially beyond London.
"While we always planned subtitles, we brought them forward when viewers contacted us in their hundreds to request better accessibility to GB News."
The service launched yesterday on GB News' feeds on Sky, Virgin Media, Freeview, Youview and Freesat.
