The main aim of the present work was to investigate whether vocal hyperfunction (VH), perceptual voice quality (VQ), gender, and phonetic environment influence Voice Onset Time (VOT). investigated group consisted 30 adults, including 19 women (X = 46.1 ± 13.7 years) 11 men 47.5 11.0 years), who had either phonotraumatic (PVH) non-phonotraumatic (NPVH). VQ judged considering overall severity dys...

Voice quality has been defined as the characteristic auditory colouring of an individual's voice, derived from a variety of laryngeal and supralaryngeal features and running continuously through the individual's speech. The distinctive tone of speech sounds produced by a particular person yields a particular voice. Voice quality is at the centre of several speech processing issues. In speech re...

In the present paper quality of voice has been analyzed in VoIP communications model. An investigation of IP-based voice communication with emphasis on the effects of a wireless channel on the quality of the received speech is attempted and the effects of voice signal compression and wireless channel conditions as well as channel coding on the voice quality and recognition are investigated thro...

Auditory voice quality judgements are used intensively for the clinical assessment of pathological voice. Voice quality concepts are fuzzily defined and poorly standardized however, which hinders scientific and clinical communication. The described database documents a wide variety of pathologies and is used to investigate auditory voice quality concepts with regard to phonation mechanisms. The...

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...

Long-term voice outcomes of 13 tracheoesophageal speakers are assessed using speech samples that were recorded with at least 7 years in between. Intelligibility and voice quality are perceptually evaluated by 10 experienced speech and language pathologists. In addition, automatic speech evaluations are performed with tools from Ghent University. No significant group effect was found for changes...

Although voices provide listeners with significant information about speakers, defining and measuring voice quality remain elusive goals. We argue that the much-maligned ANSI standard definition of sound quality is in fact an appropriate definition, because it treats quality as the result of a perceptual process rather than a fixed quantity, and highlights the interaction between listeners and ...

Mandarin Chinese is one of the well studied tone languages, and related contextual tonal variations as a function of prosody have attracted many researchers’ interest. Change of voice quality, which is not phonemic in Mandarin, is also subject to prosody. The focus of this study will be the effects of prosodic structure, focus in particular, on voice quality in Mandarin Chinese, and the results...
