We focus in this paper on the detection of emotions collected in real-life context. In order to improve our emotional valence detection system, we have tested new voice quality features that are mainly used for speech synthesis or voice transformation: the relaxation coefficient (Rd) and the functions of phase distortion (FPD); but also usual voice quality features. Distributions of voice quali...

This paper proposes techniques for flexibly controlling voice quality of converted speech from a particular source speaker based on one-to-many eigenvoice conversion (EVC). EVC realizes a voice quality control based on the manipulation of a small number of parameters, i.e., weights for eigenvectors, of an eigenvoice Gaussian mixture model (EV-GMM), which is trained with multiple parallel data s...

Cellular Wireless Wide Area Networks (WWANs) are most prevalent and offer highbandwidth data transfer. We believe WWANs can be availed for voice communications employing Voice Over IP technologies. Such a communication will be of better quality and offer higher resilience compared to voice communication over a cellular phone (using cellular voice networks). We present a Quality of Service analy...

At present, two important questions about voice remain unanswered:When voice quality changes, what physiological alteration caused this change, and if a change to the voice production system occurs, what change in perceived quality can be expected? We argue that these questions can only be answered by an integrated model of voice linking production and perception, and we describe steps towards ...

Skype, one of the popular VoIP applications, has its own redundancy mechanism to mitigate the impact of packet loss at the expense of additional bandwidth usage. However, the benefit of voice quality improvement through redundancy is reduced greatly in the case of consecutive loss of Skype packets. When Skype is running over wireless networks, the high likelihood of having consecutive packet lo...

Title of Thesis : AN ALGORITHM TO EVALUATE THE ECHO SIGNAL AND THE VOICE QUALITY IN VOIP NETWORKS Andre Neumann Kauffman, M.S., 2006 Directed By: Associate Professor, Steven A. Tretter, Department of Electrical and Computer Engineering Voice over the Internet Protocol (VoIP) has been increasingly popular, but reliability and voice quality remain important factors that limit the widespread adopt...

This paper investigates the effect of voice quality in commutative speech. Voice quality is often considered as the characteristic auditory colouring of an individual speaker's voice, but in our study, we find that voice quality can also reveal information about the interlocutor in everyday social interactions. In the correlation analysis between acoustic measures and interlocutors, the effect ...

Thoracic-surgery-related unilateral vocal fold paralysis (UVFP) may cause severe morbidity and can cause profound functional impairment and psychosocial stress in patients with pre-existing thoracic diseases. In-office intracordal hyaluronate (HA) injections have recently been applied to improve voice and quality of life in patients with vocal incompetence, but their effect on thoracic-surgery-...

An Internet telephony system is basically a computer-form of a conventional telephone to support real-time voice communication between two or more users who are connected to the Internet. Internet telephony circumvents expensive international telephone toll charges by using Internet as an intermediary medium to transport voice signals between two users. In doing so, transcontinental telephone c...
