this study examined the phonetic characteristics of persian sentence stress produced by native mandarin chinese speakers. we compared the phonetic correlates of sentence stress, namely fundamental frequency (f0), vowel duration, and vowel intensity in the production of 8 mandarin chinese speakers and 8 native persian speakers. results indicated that mandarin chinese speakers of persian could di...

Fundamental and formant frequencies influence perceived pitch and are sexually dimorphic in humans. The information content of these acoustic parameters can illuminate the forces of sexual selection shaping vocal sex differences as well as the mechanisms that ensure signal reliability. We use multiple regression to examine the relationships between somatic (height, adiposity, and strength) and ...

In a former study on changes of voice quality and fundamental frequency after glossectomy we found that the mean fundamental frequency and the distance between F0 of closed vs. open vowels changed postoperatively. The general aim of our current study is to investigate whether the changed iF0 distances can be traced back to the consequences of oral surgery or to a compensatory mechanism to enhan...

We present a new method for the estimation of a continuous fundamental frequency (F0) contour. The algorithm implements a global optimization and yields virtually error-free F0 contours for high quality speech signals. Such F0 contours are subsequently used to extract a continuous fundamental wave. Some local properties of this wave, together with a number of other speech features allow to clas...

AN ALGORITHM FOR LOCATING FUNDAMENTAL FREQUENCY (F0) MARKERS IN SPEECH Princy Dikshit Old Dominion University, December 2004 Director: Dr. Stephen A. Zahorian Speech has been the principal form of human communication since it began to evolve at least one hundred thousand years ago. Speech is produced by vibrations of the vocal cords. The rate of vibration of the cords is called fundamental freq...

Fundamental frequency (F0) variation is one of a number of acoustic cues normal hearing listeners use for guiding lexical segmentation of degraded speech. This study examined whether F0 contour facilitates lexical segmentation by listeners fitted with cochlear implants (CIs). Lexical boundary error patterns elicited under unaltered and flattened F0 conditions were compared across three groups: ...

A fundamental frequency (F0) estimator named Harvest is described. The unique points of Harvest are that it can obtain a reliable F0 contour and reduce the error that the voiced section is wrongly identified as the unvoiced section. It consists of two steps: estimation of F0 candidates and generation of a reliable F0 contour on the basis of these candidates. In the first step, the algorithm use...

This paper describes a robust method for estimating the fundamental frequency (F0) of melody and bass lines in monaural realworld musical audio signals containing sounds of various instruments. Most previous F0-estimation methods had great difficulty dealing with such complex audio signals because they were designed to deal with mixtures of only a few sounds. To make it possible to estimate the...
