The impact of changes in a speaker's vocal effort on the performance of automatic speech
recognition has largely been overlooked by researchers and virtually no speech resources …

Whisper island detection is a challenging research problem which has received little
attention in the research community. Effective whisper-island detection is the first step …

Abstract Infrequent Non-Speech Gestural Activities (IGAs) such as coughing, deglutition and
yawning help identify fine-grained physiological symptoms and chronic psychological …

Recognizing the human activity, behavior and physiological symptoms in smart home
environments is of utmost importance for the functional, physiological and cognitive health …

In this study, several improvements are proposed for improved whisper-island detection
within normally phonated audio streams. Based on our previous study, an improved feature …

In this article the significance of a new parametric spectral ratio method that can be used to
detect whispered speech segments within normally phonated speech is described …

The expansion of the video games industry raises innovative and challenging issues for
speech technologies, eg the development of automatic content-based speech processing …

Vocal effort changes induce various modifications to acoustic characteristics of speech. In
this paper we investigate the impact of raised vocal effort on the speech spectrum. In …

Non-neutral speech, especially whispered speech, has strong negative impact on speech
system performance. It is therefore necessary to detect whisper-islands embedded within …

While the challenge of non-neutral speech is attracting more research attention in recent
years, the specific speaking style of “whisper” is of particular interest in both speech …
