Robust speech systems in mobile environment have gained a special interest in recent
years in order to enable access to remote voice-activated services. In this context, three …

Transcoding steganography (TranSteg) is a fairly new IP telephony steganographic method
that functions by compressing overt (voice) data to make space for the steganogram by …

This paper describes an algorithm for detection of nonlinguistic vocalisations, such as
laughter or fillers, based on acoustic features. The algorithm proposed combines the …

This study investigated whether it is possible to train a machine to discriminate levels of
extraversion based on handwriting variables. Support vector machines (SVMs) were used …

This paper investigates the impact of non-speech sounds on the performance of speaker
recognition. Various experiments were conducted to check what the accuracy of speaker …

This article addresses the problem of anti-spoofing protection in an automatic speaker
verification (ASV) system. An improved version of a previously proposed spoofing …

The typical approach to steganography is to compress the covert data in order to limit its
size, which is reasonable in the context of a limited steganographic bandwidth. Trancoding …

In this paper, we investigate the effect of lossy speech compression on text-independent
speaker verification task. We have evaluated the voice biometrics performance over several …

It is well known that the speaker discriminative information is not equally distributed over the
spectral domain. However, it is still not clear whether that distribution is altered when the …

In this work, multi-frame thermal imagery of the face of a person is employed for drunk
identification. Regions with almost constant temperature on the face of sober and drunk …
