Pitch Contour Stylization Using a Tonal Perception Model
An algorithm for automatic pitch contour stylization is described. It is based on a model of tonal perception, such that the resulting stylization is controlled by two perceptual thresholds. The output is the sequence of audible pitch events aligned with the syllables in the utterance. INTRODUCTION Stylization is a manual or automatic procedure that modifies the measured F0 contour of an uttera...
متن کاملAutomatic pitch contour stylization using a model of tonal perception
A new quantitative model of tonal perception for continuous speech is described. The paper illustrates its ability for automatic stylization of pitch contours, with applications to prosodic analysis and speech synthesis in mind, and evaluates it in a perception experiment. After a discussion of the psychoacoustics of tonal perception and an overview of existing tonal perception models and syste...
متن کاملPiecewise linear stylization of pitch via wavelet analysis
In this paper, we propose a wavelet analysis based piecewise linear stylization of the pitch trajectory. We also address the often-faced difficulty in handling the tradeoff between mean squared error and the number of lines used for fitting, where a heuristic approach is typically used to make the stylization choice. We pose the piecewise linear stylization task as a minimization problem by def...
متن کاملRemarks on Piecewise Polynomial Approximation
The theoretical and experimental background for the approximation of "real-world" functions is reviewed to motivate the use of piecewise polynomial approximations. It is possible in practice ~o achieve the results suggested by the theory for piecewise polynomials. A convergent adaptive algorithm is outlined which effectively and efficiently computes smooth piecewise polynomial approxImations to...
متن کاملA Divide et impera Algorithm for Optimal Pitch Stylization
We present OpS, a divide et impera algorithm to address the problem of pitch stylization as an optimization process in O(NlogN). We aim at balancing the quality of the stylized curve and its cost in terms of the number of control points used. We also investigate how the occurrence of prominent syllables can be exploited to obtain less expensive stylizations. Our tests show that the basic OpS al...
