The SlideSpeech, a large-scale multi-modal audio-visual corpus with a significant amount of real-time synchronized slides, is collected from YouTube. The corpus contains 1,659 videos, 1,000+ hours, with 473 hours of high-quality transcribed speech for training (Train). Additionally, the Dev set consists of 21 videos (5.07 hours), while the Test set comprises 25 videos (8.75 hours). Unlike the Train set, annotations in the Dev and Test sets are manually labeled. Specifically, SlideSpeech covers a variety of domain categories (22 classes), including computer science, musical instruments, history, agriculture, animation, music, parenting, travel, education and others. The corpus is easy to expand or target specific scenarios. The slides in the videos also include relevant images and some facial information. This corpus can be applied for automatic subtitle generation in online education scenarios.
