Subjective measurement and objective modeling of voice quality in a conference call for a stressed listener
نویسندگان
چکیده
This paper verifies the effect of delay of voice information between the participants in a conference telephone call on the subjective assessment of the quality of the conversation. And evaluate changes in the assessment of individual respondents based on their mental state. Criterion of transmission quality is a parametr MOS obtained from respondents of subjective tests before and after the stressful situation.

متن کاملAdvances in Perceptual Speech Quality Assessment
In the context of telecommunications, speech quality is the most visible and important aspects of quality of service (QoS), and the ability to monitor and design for this quality should be a top priority. Speech quality refers to the clearness of a speaker’s voice as perceived by a listener. Its measurement offers a means of adding the human end-user’s perspective to traditional ways of perform...

متن کاملUsing Context-based Statistical Models to Promote the Quality of Voice Conversion Systems
This article aims to examine methods of optimizing GMM-based voice conversion systems performance in which GMM method is introduced as the basic method for improvement of voice conversion systems performance. In the current methods, due to using a single conversion function to convert all speech units and subsequent spectral smoothing arising from statistical averaging, we will observe quality ...
متن کاملHMM-based stressed speech modeling with application to improved synthesis and recognition of isolated speech under stress
In this study, a novel approach is proposed for modeling speech parameter variations between neutral and stressed conditions and employed in a technique for stressed speech synthesis and recognition. The proposed method consists of modeling the variations in pitch contour, voiced speech duration, and average spectral structure using hidden Markov models (HMM’s). While HMM’s have traditionally b...
