Abstract

Научно-технический вестник информационных технологий, механики и оптики, Mechanics and Optics, 2018, vol. 18, no. 2, pp. 346-349 (in Russian). doi: 10.17586/2226-1494-2018 Abstract Nowadays there are a lot of continuous studies on the correct viseme classes to be used for the most effective automatic lipreading. The paper proposes a structured approach for the development of speaker-dependent classes of visemes. This method
