Facial motion during speech is a direct consequence of vocal-tract motion which also
shapes the acoustics of speech. This fact suggests that speech acoustics can be used to …

Biometric characteristics can be utilized in order to enable reliable and robust-to-impostor-
attacks person recognition. Speaker recognition technology is commonly utilized in various …

This study examines relationships between external face movements, tongue movements,
and speech acoustics for consonant-vowel (CV) syllables and sentences spoken by two …

Continuous latent variable models (cLVMs) are probabilistic models that represent a
distribution in a high-dimensional Euclidean space using a small number of continuous …

Over the past several decades, behavioral studies in experimental psychology have
revealed several intrigu-ing audiovisual (AV) speech perception effects. Under noisy …

In this chapter we address the audiovisual integration of information for speech. We first
summarize the spatial and temporal features of normal speech communication and the …

This paper presents a visual passwords system to increase security. The system depends
mainly on recognizing the speaker using the visual speech signal alone. The proposed …

In this paper we propose a novel fusion protocol based on fuzzy fusion of face and voice
features for checking liveness in secure identity authentication systems based on face and …

In this paper, we quantify the time-varying coordination of articulator motion for two speakers
engaged in two face-to-face speaking tasks: repetition of simultaneously produced words …

This study is a first step towards quantifying the relationship between external orofacial
movements, tongue movements, and the acoustics (AC) of speech sounds. The database …
