Abstract:
Speechreading or lipreading is the technique of understanding and getting phonetic features from a speaker's visual features such as movement of lips, face, teeth and tongue. It has a wide range of multimedia applications such as in surveillance, Internet telephony, and as an aid to a person with hearing impairments. Our lab (MIDAS:Multimodal Digital Media Analysis Lab) has worked on several aspects of lipreading both as an application as well as theory. We started with viewing it as converting silent speech videos to speech and text and now, we are working on utilizing the same for helping people suffering from various pathologies such as aphasia, dysarthria, etc. Speech, the same as language, is severely limited by the datasets the research community has. The problem gets more aggravated in case of low resource languages like Hindi and Tamil. Even for high resource languages like English, they are restricted by the vocabulary size they contain. For e.g., the largest lipreading dataset contains no more than a few thousand unique English words. Thus, one of our goals has been to overcome these limitations of the current systems by generalizing it to different languages and extending its vocabulary size. All of this has helped us to use the capabilities of lipreading on modern applications such as video streaming and live video generation.
