Visual Keyword Spotting

Visual Keyword Spotting is a subtask in the field of computer vision that aims to identify specific query keywords from silent videos of speaking faces. This technology achieves precise localization and recognition of keywords by analyzing changes in lip movements and facial expressions in the video. Its application value is extensive, including but not limited to enhancing the robustness of speech recognition systems, assisting the hearing impaired in understanding and interacting, and extracting and processing information in noisy environments.
