Authoring tools probably can not provide any analysis capabilities for sync issues on the user added segments. However, the responsibility of aligning any new captions you add lies with you. ![]() Since the raw captions are generated by the tool itself, they are expected to be aligned with the converted audio. Authoring systems may provide basic measurements such as CPS (Characters Per Second), WPM (Words Per Minutes) and CPL (Characters Per Line) that will allow you to rectify the basic ‘timing’ issues. An operator is required to then add the captions missed by the ASR technology and properly align/format all the captions as needed. To further clarify and differentiate between caption authoring tools and caption QC tools, we will examine some scenarios to help you appreciate the importance of specialized caption QC systems.Ī common authoring system will let you generate raw captions using ASR (Automated Speech Recognition) technology that provides the first draft of the captions. The advent of advanced and automated caption QC software, such as CapMate from Venera Technologies, is now providing a logical alternative to the tedious manual caption QC process, allowing automation of a large portion of this process. The caption QC until recently, had remained a time-consuming and resource intensive manual process. While caption authoring is used to create captions and subtitles, caption QC is an increasingly important part of any caption/subtitle workflow in order to ensure the optimum end-user experience when viewing captions. So, we thought it is worthwhile to clarify and differentiate the role each software category provides.Ĭaption/Subtitle Authoring and Caption/Subtitle QC remain two separate and distinct activities. ![]() We often see content creators and distributors contemplate the difference between a Caption Authoring system and a Caption/Subtitle QC system and whether they are both needed. The presence of captions and subtitles with digital media files has become more prominent and nearly universal.
