Analysis and modeling of the effect of paralinguistic information upon the local speech rate

چکیده
The local speech rate is one of the important prosodic parameters for representing both linguistic and paralinguistic information. The present paper presents a command-response model for the process of speech rate control, and applies it to the analysis of the effects of emphasis on the local speech rate in English utterances. It shows that the local speech rate as a function of time can be approximated by the smoothed response of a second-order linear system for speech rate control to a set of underlying commands, whose timings and amplitudes serve as quantitative parameters for representing paralinguistic information. Together with the command-response model for F0 contour generation, it provides a unified approach to the quantitative analysis of paralinguistic information in prosody.

1. Introduction In human communication, speech conveys not only linguistic information but also emphasis, intention, attitude and so on. They are called paralinguistic information [1]. There are several researches on paralinguistic information [2,3]. Methods for modeling or detecting of paralinguistic information is useful for various application in man-machine communication such as speech synt...

Few, if any, studies have investigated the effect of professional experience as a rater variable and type of assessment as a task variable on raters’ criteria in the assessment of speech acts. This study aimed to explore the impact of nonnative teachers’ professional experience on the use of criteria in monologic and dialogic assessment of 12 role-plays of 3 apology speech acts. To this end, 60...

Influence of paralinguistic information upon articulatory gesture was examined using EMMA record of tongue, jaw and lips. The focus was upon the contrast between “admiration” and “suspicion.” It was found that previously reported contrast in F2 is related to the horizontal displacement of the tongue body and lip aperture control. These articulatory characteristics were observed not only in vowe...
