Continuous Audio-visual Speech Recognition Continuous Audio-visual Speech Recognition

We address the problem of robust lip tracking, visual speech feature extraction, and sensor integration for audiovisual speech recognition applications. An appearance based model of the articulators, which represents linguistically important features, is learned from example images and is used to locate, track, and recover visual speech information. We tackle the problem of joint temporal model...

Gaze-based Assistive Technologies

The eyes play an important role both in perception and communication. Technical interfaces that make use of their versatility can bring significant improvements to those, who are unable to speak or to handle selection tasks elsewise, e.g. with their hands, feet, noses or tools handled with the mouth. Using the eyes to enter texts into a computer system, which is called gaze-typing, is the most ...

Audio signals in speech interfaces

This paper discusses a variety of types of non-lexical signals such as beeps, prosodic variation and speaker style changes, and we consider four cases in which such signals might be used to good effect. We discuss the results of user tests to determine if specific types of non-lexical signals are better in some situations than in others, and we discuss the advantages and disadvantages of using ...

Speech and Language processing as assistive technologies

The talk will distil experience and results from several projects, over more than a decade, which have researched and developed the application of speech recognition as an input modality for assistive technology (AT). Current interfaces to AT for people with severe physical disabilities, such as switch-scanning, can be prohibitively slow and tiring to use. Many people with severe physical disab...

Inventory-Based Audio-Visual Speech Enhancement

In this paper we propose to combine audio-visual speech recognition with inventory-based speech synthesis for speech enhancement. Unlike traditional filtering-based speech enhancement, inventory-based speech synthesis avoids the usual trade-off between noise reduction and consequential speech distortion. For this purpose, the processed speech signal is composed from a given speech inventory whi...
