This thesis presents new parameters based on the HOS (Higher-Order Statistics) analysis to improve the classification performance of a multi-stage pathological voice assessment system. Automatic pathological diagnosis is a field which still demands further investigation mainly due to the difficulty in quantifying or standardizing the speech pathologists’ diagnoses. In recent years, various spee...

VoIP services are scarifying, due to delay in transmission of voice packets (Latency), echo, jitter, packet loss and other Quality of Service (QoS) problems arrived in VoIP phones. The weakness on QoS is managing by voice and data service together on a VoIP network. In this paper we dedicated to studying the response of data transmission quality, characteristic of voice quality, the service qua...

The present study investigates the relationship of linguistic (phonetic) and extralinguistic (voice) information in preattentive auditory processing. We provide neurophysiological data, which show for the first time that both kinds of information are processed in parallel at an early preattentive stage. In order to establish the temporal and spatial organization of the underlying neuronal proce...

This paper reports the results of a controlled field experiment in which voice communication was introduced into an existing online community (online gaming guilds within the popular game ‘‘World of Warcraft’’), comparing a mix of voice and text with text only. Quantitative results suggest increases in liking and trust due to the addition of voice, as well as insulation from unexpected negative...

Multi-dimensional properties of audio data and resourcepoor nodes make voice processing and transmission a challenging task for Wireless Sensor Networks (WSN). This study analyzes voice quality distortions caused by packet losses occurring over a multi-hopWSN testbed: A comprehensive analysis of transmitted voice quality is given in a real setup. In the experiments, recorded signals are partiti...

In the present study, the effects of emotional tone of voice on the perception of word meaning were investigated. In two experiments, listeners were presented with emotional homophones that had one affective meaning (happy or sad) and one neutral meaning. In both experiments, the listeners were asked to transcribe the emotional homophones presented in three different affective tones--happy, neu...

We introduce a technique for augmenting neural text-to-speech (TTS) with lowdimensional trainable speaker embeddings to generate different voices from a single model. As a starting point, we show improvements over the two state-ofthe-art approaches for single-speaker neural TTS: Deep Voice 1 and Tacotron. We introduce Deep Voice 2, which is based on a similar pipeline with Deep Voice 1, but con...

Non-adherence to prescribed medical treatment is a major health problem especially with chronic diseases such as HIV/AIDS, Diabetes, Tuberculosis and Malaria for which medication adherence is very critical especially in outpatient setting. This paper presents a voice-based mobile medical alert system (Voice MedAlert) for outpatient adherence. The system runs on client server architecture respon...

Effective interactions between conspecific individuals can depend upon the receiver forming a coherent multisensory representation of communication signals, such as merging voice and face content. Neuroimaging studies have identified face- or voice-sensitive areas (Belin et al., 2000; Petkov et al., 2008; Tsao et al., 2008), some of which have been proposed as candidate regions for face and voi...

Voice disorders are a source of increasing concern as normal voice quality is a social demand for at least one third of the population in developed countries in cases where voice is an essential resource in professional exercise. In addition, the growing exposure to certain pathogenic factors such as smoking, alcohol abuse, air pollution, and acoustic contamination, and other problems such as g...
