On Smoothing and Enhancing Dynamics of Pitch Contours Represented by Discrete Orthogonal Polynomials for Prosody Generation

The Function of Pitch Range Variations in Samples of Emotional Expressions in Persian

This study aims at investigating the interface between emotion and intonation patterns (more specifically, duration and pitch amplitude of speech). To this end, the acoustic properties of spectral parameters related to speech prosody are investigated. The results of acoustic and Statistical analysis show that mean level and range of FO in the contours vary strongly as a function of the degree o...

Recurrences and explicit formulae for the expansion and connection coefficients in series of the product of two classical discrete orthogonal polynomials

Suppose that for an arbitrary function $f(x,y)$ of two discrete variables, we have the formal expansions. [f(x,y)=sumlimits_{m,n=0}^{infty }a_{m,n},P_{m}(x)P_{n}(y),] $$‎ ‎x^{m}P_{j}(x)=sumlimits_{n=0}^{2m}a_{m,,n}(j)P_{j+m-n}(x)‎,$$ ‎we find the coefficients $b_{i,j}^{(p,q,ell‎ ,‎,r)}$ in the expansion‎ $$‎ ‎x^{ell }y^{r},nabla _{x}^{p}nabla _{y}^{q},f(x,y)=x^{ell‎ ‎}y^{r}f^{(p,q)}(x,y) =sumli...

The implementation of phrasal prosody by native and non-native speakers of English: SS ANOVA for multi-syllabic intonation contours

Non-native speakers often have difficulties with prosody; stress and intonation patterns that differ from those of native speakers can contribute to “foreign accent,” even at high proficiency levels. Although effects of a listener’s native language on the perception of prosody are well established, few studies have examined non-native prosody production. In particular, it is not known whether t...

A Remark on a Remark by Macaulay or Enhancing Lazard Structural Theorem

Characterization of Emotions Using the Dynamics of Prosodic Features

In this paper the dynamics of prosodic parameters are explored for recognizing the emotions from speech. The dynamics of prosodic parameters refer to local or fine variations in prosodic parameters with respect to time. The proposed dynamic features of prosody are represented by : (1) sequence of durations of syllables in the utterance (duration contour), (2) sequence of fundamental frequency v...
