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

The Role of Fundamental Frequency in Phonetic Accommodation

Language and Speech, 2011
Previous research has argued that fundamental frequency is a critical component of phonetic accommodation. We tested this hypothesis in an auditory naming task with two conditions. Participants in an Unfiltered Condition completed an auditory naming task with a single male model talker.

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.

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 Stability in Functional Dysphonia

Acta Oto-Laryngologica, 1993
Functional dysphonia is a term applied to voice disorders for which there is an absence of apparent structural change in the larynx. The aim of this work was to investigate how functional dysphonia may differ acoustically from other types of dysphonia.

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.

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.

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.

Nonconscious control of fundamental voice frequency

The Journal of the Acoustical Society of America, 2008
The aim of this paper is to answer the question whether “perception-action” dissociation, which is well documented in vision, may also be found in auditory information processing. Trained singers were asked to produce vowel sounds into a microphone. The sound that each singer produced was fed back to their ears via headphones.
