The paper describes an auditory experiment aimed at testing whether the intrinsic loudness of a stimulus with a given voice quality influences the way in which it signals affect. Synthesised voice quality stimuli in which intrinsic loudness was systematically manipulated were presented to listeners to test the effect of this manipulation on the affective colouring of the stimuli. The results sh...

Academic writing is not just about presenting a set of ideas, but through the act of writing, the authors position themselves as individuals having particular identities which mostly reflect the dominant sociocultural values and practices of the discourse communities in which they are living and performing. The present study, using a mixed method approach, attempted to explore the evidences of ...

This paper discusses the voice quality of Opus, IETF driven open source voice and audio codec. Opus is a newly developed hybrid codec based on SILK and CELT codec technologies. Opus construction is described shortly in this paper and more importantly its optimal operating points are found out based on the listening test results. Voice quality was evaluated with two subjective listening tests. I...

THE outline of a componential descriptive model of voice quality is suggested, in the hope of facilitating discussion about voice quality among phoneticians, linguists, speech therapists, psychologists and psychiatrists. Emphasis is laid on the function of voice quality as an index to biological, psychological and social characteristics of the speaker.

In human speech production, the voice source contains important non-lexical information, especially relating to a speaker’s voice quality. In this study, direct measurements of the glottal area waveforms were used to examine the effects of voice quality and glottal gaps on voice source model parameters and various acoustic measures. Results showed that the open quotient parameter, cepstral peak...

OBJECTIVES A wide range of well validated instruments is now available to assess voice quality and voice-related quality of life, but comparative studies of the responsiveness to change of these measures are lacking. The aim of this study was to assess the responsiveness to change of a range of different measures, following voice therapy and surgery. DESIGN Longitudinal, cohort comparison stu...

In this paper we investigate the prosody and voice quality of dominance in scenario meetings. We have found that in these scenarios the most dominant person tends to speak with a louder-than-average voice quality and the least dominant person with a softer-than-average voice quality. We also found that the most dominant role in the meetings is the project manager and the least dominant the mark...

Robust Header Compression (ROHC) has recently been proposed to reduce the large protocol header overhead when transmitting voice and other continuous media over RTP/UDP/IP in wireless networks. In this paper we evaluate the real-time transmission of GSM encoded voice with ROHC over a wireless link. We first present a tutorial on voice quality evaluation. We introduce an evaluation methodology t...

Voice over Internet Protocol (VoIP) is being widely deployed to offer users low-cost alternatives for long-distance and international telephone calls. However, for users who are accustomed to the high-quality sound offered by traditional Public Switched Telephone Network (PSTN) service, VoIP voice quality often pales in comparison. Voice quality in VoIP networks widely varies as a result of sev...
