Inês Nolasco, Alessandro Terenzi, Stefania Cecchi +3
The absence of the queen in a beehive is a very strong indicator of the need for beekeeper intervention. Manually searching for the queen is an arduous recurrent task for beekeeper…
The speaker-independent lipreading play-off; a survey of lipreading machines
Jake Burton, David Frank, Madhi Saleh +2
Lipreading is a difficult gesture classification task. One problem in computer lipreading is speaker-independence. Speaker-independence means to achieve the same accuracy on test s…
An extensible cluster-graph taxonomy for open set sound scene analysis
Helen L Bear, Emmanouil Benetos
We present a new extensible and divisible taxonomy for open set sound scene analysis. This new model allows complex scene analysis with tangible descriptors and perception labels.…
Visual Speech Language Models
Helen L Bear
Language models (LM) are very powerful in lipreading systems. Language models built upon the ground truth utterances of datasets learn grammar and structure rules of words and sent…
Comparing heterogeneous visual gestures for measuring the diversity of visual speech signals
Helen L Bear, Richard Harvey
Visual lip gestures observed whilst lipreading have a few working definitions, the most common two are; `the visual equivalent of a phoneme' and `phonemes which are indistinguishab…
Phoneme-to-viseme mappings: the good, the bad, and the ugly
Helen L Bear, Richard Harvey
Visemes are the visual equivalent of phonemes. Although not precisely defined, a working definition of a viseme is "a set of phonemes which have identical appearance on the lips".…
Comparing phonemes and visemes with DNN-based lipreading
Kwanchiva Thangthai, Helen L Bear, Richard Harvey
There is debate if phoneme or viseme units are the most effective for a lipreading system. Some studies use phoneme units even though phonemes describe unique short sounds; other s…
