Vowel identity correlates well with the shape of the transfer function of the vocal tract, in particular the position of the first two or three formant peaks. However, in voiced speech the transfer function is sampled at multiples of the fundamental frequency (F0), and the short-term spectrum contains peaks at those frequencies, rather than at formants. It is not clear how the auditory system e...

A stochastic representation of singing styles is proposed. The dynamic property of melodic contour, i.e., fundamental frequency (F0) sequence, is assumed to be the main cue for singing styles because it can characterize such typical ornamentations as vibrato . F0 signal trajectories in the phase plane are used as the basic representation. By fitting Gaussian mixture models to the observed F0 tr...

Intonational research is often dependent upon hand-labeling by trained listeners, which can be prone to bias or error. We apply tools from Functional Data Analysis (FDA) to a set of fundamental frequency (F0) data to demonstrate how these tools can provide a less theory-dependent way of investigating F0 contours by allowing statistical analyses of whole contours rather than depending on theoret...

Studies of the relationship between prosody and the topic structure of longer discourses have tended to focus on intonational cues, most specifically fundamental frequency (F0). However, this may limit the kinds of topic structure it is possible to identify. A case study of two speakers shows that including speech rate along with F0 factors in an analysis of the prosody of topic structure can b...

Modeling the speech generation process can provide flexible and interpretable ways to generate intended synthetic speech. In this paper, we present a deep generative model of fundamental frequency (F0) contours of normal speech and singing voices. The generative model we propose in this paper 1) is able to accurately decompose an F0 contour into the sum of phrase and accent components of the Fu...

This paper presents the developmental fundamental frequency (F0) data from Cantonesespeaking pre-adolescent children, male and female. Results of frequency analysis of the speech data from children of nine age groups from 4 to 12 years show that (i) there is an overall drop in F0 across the nine age groups of both genders and a larger change for male than female children; (ii) a significant dif...

With an average male body mass of 320 kg, the wapiti, ITALIC! Cervus canadensis, is the largest extant species of Old World deer (Cervinae). Despite this large body size, male wapiti produce whistle-like sexual calls called bugles characterised by an extremely high fundamental frequency. Investigations of the biometry and physiology of the male wapiti's relatively large larynx have so far faile...

A corpus-based method of generating fundamental frequency (F0) contours of various speaking styles from text was developed. Instead of directly predicting F0 values, the method predicts command values of the F0 contour generation process model. Because of the model constraint, the resulting F0 contour keeps certain naturalness even when the prediction is done incorrectly. The method includes a ...

The physiological background of sentence declination (fundamental frequency, F0, drop) was studied using ultrasound (US) examination of the cricothyroid (CT) space. The US probe was placed anteriorly in the region of middle cricothyroid ligament. The echoes caused by the antero-inferior edge of thyroid and antero-superior edge of the cricoid cartilages were used as points of measurement. The te...
