The paper first presents the factors affecting end-to-end speech quality in VoIP, such as end-to-end frame loss/concealment and end-to-end jitter. It then discusses how these factors affect the current objective speech quality measurement algorithms and suggests essential modifications for VoIP. It also highlights extensions to the basic objective measurement, such as time-varying speech measur...

We use language every day without devoting much thought to the process, but articulatory movement—the movement of the lips, tongue, and other organs—is among the subtlest and most adept of any actions performed by human beings. Here, I discuss the mechanisms of speech production, introduce functions for producing sound by controlling the movement of vocal organs, and consider models for achievi...

This study compares affective piano performance with speech production from the perspective of dynamics: unlike previous research, this study uses finger force and articulatory effort as indexes reflecting the dynamics of affective piano performance and speech production respectively. Moreover, for the first time physical constraints such as piano fingerings and speech articulatory constraints ...

Wearing a face mask affects the speech production. On top of that, the frequency response and radiation characteristics of the face mask depending on the material and shape of the mask adds to the complexity of analyzing speech under face mask. Our target is to separate the effect of muscle constriction and increased vocal effort in speech produced under face mask from sound transmission and ra...

Traditionally, literacy, and speech production have been investigated separately. Studies of development demonstrate that children are able to meet the challenge of language learning across modalities, and that adults may experience difficulties in one or both modalities. Yet, it is rare to find a conceptual connection between these two processes. I argue that speaking and reading actually shar...

The measurement of parameters from the output acoustic pressure waveform during speech has been a common activity in speech science laboratories for a number of decades. The widespread availability of personal computers with more than adequate processing capability to carry out speech analysis means that speech analysis is now commonly available and many more users have access to it. Indeed, th...
