AppTek integrates its latest speaker change technology into its closed captioning platform.

Applications Technology (AppTek), today announces the inclusion of speaker change detection in the latest release of its automatic closed captioning platform technology – AppTek Caption. The release includes updates to its proprietary Automated Speech Recognition (ASR) engine with specific models for news, entertainment and general use and automated punctuation technology in addition to the inclusion of new speaker change detection.

“Our research has shown that the hearing-impaired community finds the viewing experience of our closed captioning platform preferable to the electronic newsroom techniques and on-par with human transcription. With the inclusion of our speaker change identification and the latest improvements to our automated punctuation, we continue to make our captioning platforms more accurate and engaging for the audiences we serve,” stated Adam Sutherland, AppTek CEO. “The AppTek team’s deep expertise in neural networks, machine learning and artificial intelligence allow us to continue to make breakthroughs in ASR technology as well as commercial products based on that technology.”

The latest update increases the accuracy and readability of the captions produced for either live or pre-recorded content. Adding indication for speaker change dramatically improves the flow and understanding of closed captions and subtitles.
