Automatic live subtitling on the cards

Support of the Speechmatics automatic speech recognition technology within the company’s subtitle transmission and creation workflows has been announced. According to Screen Subtitling Systems, this represents a dramatic step forward in live, speaker-independent automatic speech recognition, and allows the realisation of a long held ambition – live automatic subtitling and captioning.

A prototype system is being demonstrated on the stand in Hall 1.Dean Wales, head of marketing and PR, Screen Subtitling Systems, said: “When using the high-quality audio typical of a live broadcast television programme, the Speechmatics system returns extremely fast and accurate transcripts that are immediately converted into subtitles and transmitted with the TV service.

“In addition, the integration will allow the automated production of accurate transcripts for live TV programmes, enhancing search and archive possibilities for live TV content,” added Wales.

Screen Systems is also announcing a new initiative with Institut für Rundfunktechnik to offer a subtitle file validation service through the online toolkit, created in development with fellow subtitling technology company OOONA. This is also being demonstrated on the company’s IBC stand.

Initially targeted at the IMSC 1 format of subtitle content used by major content providers, the service performs a number of tests covering both standards compliance and other qualitative metrics.

The intention, said Screen, is to expand the online system to cover additional popular subtitle formats, and to establish an authoritative service for validating and certifying subtitle files for both content creators and distributors alike.
