Some normative data on lip-reading skills (L)

Lip-reading and Bilingualism

This study investigated whether observers can identify what language was being spoken in visual-only speech stimuli, and whether or not this ability depends on an observers’ prior linguistic experience. Participants watched visual-only speech stimuli and were asked to decide if the talker in the video was speaking English or Spanish. Four groups of participants were studied: monolinguals and bi...

Lip Reading in Profile

There has been a quantum leap in the performance of automated lip reading recently due to the application of neural network sequence models trained on a very large corpus of aligned text and face videos. However, this advance has only been demonstrated for frontal or near frontal faces, and so the question remains: can lips be read in profile to the same standard? The objective of this paper is...

Towards Unrestricted Lip Reading

Lip reading provides useful information in speech perception and language understanding, especially when the auditory speech is degraded. However, many current automatic lip reading systems impose some restrictions on users. In this paper, we present our research e orts, in the Interactive System Laboratory, towards unrestricted lip reading. We rst introduce a top-down approach to automatically...

Some observations on computer lip-reading: moving from the dream to the reality

In the quest for greater computer lip-reading performance there are a number of tacit assumptions which are either present in the datasets (high resolution for example) or in the methods (recognition of spoken visual units called “visemes” for example). Here we review these and other assumptions and show the surprising result that computer lip-reading is not heavily constrained by video resolut...
