The fundamental frequency of phonation (F0) change per unit change in transglottal pressure (dF/dP) was studied at different extension lengths and masses of the vibrating part of a rubber model. The dF/dP was decreased when the vibrating part was extended, and also when the mass of the vibrating part was increased. In the former, the F0 was increased, and in the latter, the F0 was decreased. In...

A model for the generation of fundamental frequency contours (F0contours) of spoken, sentences is presented for the purpose of elucidating the relationship between the sentence F0 contour and the linguistic and non-linguistic information. It is based on a quantitative formulation of the process whereby the logarithmic fundamental frequency is controlled in proportion to the sum of two component...

The pubertal voice in musically trained (voice conscious) boys and girls was investigated with voice range profiles and fundamental frequency (F0) in running speech during reading of a standard text. The methods were based on: 1) development and evaluation of the function of phonetograph 8301 made by the firm Voice Profile, 2) combined electroglottographic and stroboscopic examination of the mo...

Functional measurement was utilized to study the acoustic cues that contribute to the perception of the voicing difference in/zi/and/si/. Rather than simply varying the acoustic signal along a single dimension and observing the effect on perception, changes along two acoustic dimensions were covaried in a factorial manner. The time between the onset of the syllable and the onset of vocal-cord v...

Prosodic cues (namely, fundamental frequency, energy and duration) provide important information for speech. For a tonal language such as Chinese, fundamental frequency (F0) plays a critical role in characterizing tone as well, which is an essential phonemic feature. In this paper, we describe our work on duration and tone modeling for telephone-quality continuous Mandarin digits, and the appli...

This paper focuses on three key points of intonation modelling: interpolation of fundamental frequency contour, sentence by sentence parameter extraction and data scarcity. In some cases, they introduce noise and inconsistency on training data reducing the performance of machine learning techniques. We consider that the F0 contour is segmented into prosodic units (such as accent groups, minor p...

This study presents an acoustic analysis of emotion. The material consisted of two semantically neutral utterances spoken by two actors, one male, one female, portraying three moods: anger, happiness and sadness; and a neutral tone. The duration, fundamental frequency (F0) and an estimate of the sound intensity (RMS) were analysed. The fundamental frequency parameter was the most revealing, sho...

We study the effects of modeling tone in Mandarin speech recognition. Including the neutral tone, there are 5 tones in Mandarin and these tones are syllable-level phenomena. A direct acoustic manifestation of tone is the fundamental frequency (f0). We will report on the effect of f0 on the acoustic recognition accuracy of a Mandarin recognizer. In particular, we put f0, its first derivative (f0...

This paper deals with the fundamental frequency estimation for monophonic sounds in the SMS analysis environment. The importance of the fundamental frequency as well as some uses in SMS is commented. The particular method of F0 estimation based on a two-way mismatched measure is described as well as some modifications. Finally we explain how pitch-unpitched decision is performed.
