There is an increasing number of rich content that includes audio and presentations. It is important to caption these contents to assure accessibility for hearing impaired persons and seniors. Initially, we conducted a survey and found that the combination of video with audio, captions, and presentation slides (hereafter "multimedia composite") is helpful in understanding the content. Also our investigation shows that the availability of captioning is still very low and therefore there is a strong need for an effective captioning system. Based on this preliminary survey and investigation, we would like to introduce a new method which integrates caption editing software with presentation software. Three major problems are identified: Content layout definition, editing focus linkage, and exporting to speaker notes. This paper will show how our Caption Editing System with Presentation Integration (CESPI) solves these problems. Experiments showed 37.6% improvement in total editing time.
