Fundamental frequency tracking in diplophonic voices [PDF]

Biomedical Signal Processing and Control, 2017
Abstract Background and objectives Fundamental frequency ( f o ) extraction in disordered voices is a prerequisite for many types of clinical analyses. Special attention must be paid if multiple oscillators with different f o s are active simultaneously. Two independent approaches to f o tracking in diplophonic voices are proposed and compared

Estimation of fundamental frequencies

IEE Proceedings F Radar and Signal Processing, 1993
Although heuristical in nature, cepstrum analysis is probably the most familiar tool for estimating the fundamental frequency (FF) of a periodic signal embedded in noise. The reason might be that model-based procedures designed to determine the FF either are likely to estimate pure fractions of the true frequency or else require a priori information ...

Fundamental Frequency Peak Delay in Mandarin

Phonetica, 2000
Abstract Fundamental frequency (F₀) peak delay (henceforth peak delay) refers to the phenomenon that an F₀ peak sometimes occurs after the syllable it is associated with either lexically or prosodically. Although peak delay has been reported for various languages, the mechanism of its occurrence has so far remained unclear.

Fundamental frequency determination based on instantaneous frequency estimation

Signal Processing, 1995
Abstract For certain types of speech coding algorithms, it is important to determine accurately the pitch period or the fundamental frequency of the speech signals. A new fundamental frequency determination method based on the instantaneous frequency estimation is presented in this paper.

Fundamentals of Frequency Control

2018
In this chapter, the concepts regarding frequency, as a basic parameter of power systems are described. Initially, the physical phenomenon, based on that, this parameter is affected and how it can be controlled are explained. A short historical view on frequency is then followed. It is then discussed how the players in a power system may be affected by

Cigarette smoking and voice fundamental frequency

Journal of Communication Disorders, 1982
The effects of long-term cigarette smoking were examined in a series of phonatory tasks. The results indicated that a significant difference existed between the fundamental frequency of the male smokers and the male nonsmokers in the oral reading and spontaneous speech tasks.

A comprehensive model for fundamental frequency generation

ICASSP '76. IEEE International Conference on Acoustics, Speech, and Signal Processing, 1976
From these studies, it is possible to model the fundamental frequency (F0) contours for sentences which exhibit a comprehensive range of linguistic communicative functions, and thus extend the understanding of the role of F0 from simple declarative sentences to a class which more nearly typifies the utterances found in nornsl discourse.

Analysis of Fundamental Frequency Contours in Speech

The Journal of the Acoustical Society of America, 1971
Many factors contribute to the variability of an ensemble of measured fundamental frequency (Fo) contours. These include, among others, differences between speakers, differences between replications of the utterance by the same speaker, and errors of estimation.

Contributions of Fundamental Frequency and Formant Frequencies to Speaker Identification

Phonetica, 1975
Abstract This experiment in aural speaker identification attempts to ascertain the relative contributions of fundamental frequency and formant frequencies. Speech samples were four voiced, whispered, and low-pass filtered isolated vowels produced by eight male speakers.
