This article analyzes the application of Chinese speech recognition technology in a non-barrier education system, and studies the construction of bi-modal database for a barrier-free teaching system. Barrier-free teaching is a term used to define systems that are designed to assist deaf students, while bi-modal approaches use both audio and video to assist learning. Based on a case study of a curriculum named “Foundations of Photoshop,” the article creates a corpus to make acquisition of experimental data and annotation of corpora. Meanwhile, the authors analyze and design the organization of data and build an essential dictionary and grammar network in the recognition system.
