Disentangling Homophemes in Lip Reading using Perplexity Analysis

no code implementations28 Nov 2020 Souheil Fenghour, Daqing Chen, Kun Guo, Perry Xiao

This paper proposes a method to tackle the one-to-many mapping problem when performing automated lip reading using solely visual cues in two separate scenarios: the first scenario is where the word boundary, that is, the beginning and the ending of a word, is unknown; and the second scenario is where the boundary is known.
