A Fundamental Frequency Data Acquisition System (FFDAS).
… but the human listener perceives the lowest frequency in the harmonic series, the fundamental frequency (FO), as the pitch of the speaker’s voice at any given instant in time. Fundamental frequency in human speech conveys linguistic (semantic, syntactical, and lexical) information, as well …

Real-Time Fundamental Frequency Estimation Algorithm for Disconnected Speech
A new algorithm is presented for real-time fundamental frequency estimation of speech signals. This method extends and alters the YIN algorithm, which uses the autocorrelation-based difference function, by adding features to reduce latency, correct predictable errors, and make it structurally …

An Investigation of Fundamental Frequency Limitations for HF/VHF Power Conversion
… chiefly be attributed to increases in switching frequency. It is to be expected that the trends towards miniaturization will maintain steady pressure to keep this pace of increasing switching frequencies of power converters. However certain fundamental limits in high frequency power conversion …

Possible Effects of Voice Fundamental Frequency, Gender and Tongue Position on Phonation Threshold Pressure
… Pth was studied as a function of voice fundamental frequency (f₀), gender, and tongue position. Ten adult native speakers of American English (five men and five women) with no known history of respiratory, laryngeal, speech and hearing problems served as subjects. Subjects were asked to …

Four -Way Stop Contrasts in Hindi: An Acoustic Study of Voicing, Fundamental Frequency and Spectral Tilt
Spectral intensity analysis of contrasting breathy and modal vowels in Gujarati, !Xoo and languages which make use of the breathy and modal phonation type as contrastive features provide a background against which spectral analysis of the breathy/murmured release following VAS can be conducted to …

Improving individual identification of wolves (Canis lupus) using the fundamental frequency and amplitude of their howls: a new survey method
… individual mammals from variations in the fundamental frequency (F0) of their vocalizations. Other characteristics of vocalization which encode individuality, such as amplitude, are less frequently used because of problems with background noise and recording fidelity over distance. In this …

The Effects of Different Auditory Feedback Conditions on Speech Rate and Self-Perceptions of Speech
… 1, 3, and 5 millisecond delayed, amplified fundamental frequency; and normal auditory feedback. Dependent variabes were rate and self-perceptions of speech. Research hypotheses were: 1) any manipulation of auditory feedback affects rate and self-perceptions of speech in non-stutterers, 2) …

Vibration Characteristics of Thin-Walled Noncircular Composite Cylinders
… interest is the variation of the lowest natural frequency, the so-called fundamental frequency, as a function of wall laminate properties, cross-sectional eccentricity and other cylinder geometric parameters. Both simple and clamped support boundary conditions are investigated. Laminate …

Improving Understanding of Emotional Speech Acoustic Content
… is the inability to accurately portray the fundamental frequency contour of speech which carries the majority of information needed to identify emotional intent. Without reliable access to the fundamental frequency, other methods of identifying vocal emotion, if identifiable, could be used …

Modeling and frequency tracking of marine mammal whistle calls
… Since the whistle calls are composed of frequency modulated harmonic tones, they are best modeled as a weighted superposition of harmonically related sinusoids. Previous research with bottlenose dolphin whistle calls has produced synthetic whistles that sound too “clean” for use in a …

How individuals with Parkinson's disease modify their speech in a repetition for clarification
… measures of vocal intensity (loudness), fundamental frequency (pitch), and utterance duration were made for repetitions of a ‘misheard’ phrase. In one experimental condition noise was presented through headphones to induce the Lombard effect. Both individuals with PD and controls used …

Characterization of the singing voice from polyphonic recordings
… the vocal line characteristics. First, the exact fundamental frequency track for the voice is estimated using the score notes as guides. Next, the harmonic strengths are estimated using the fundamental frequency information. Third, estimates in notes are automatically validated or discarded based …

Experimental characterization of the dynamic response of a mock-up CANDU fuel bundle
… using dummy endplates. The results show that the fundamental frequency of the fuel elements changes depending on the contact conditions with the neighboring fuel bundles. Furthermore, the endplates exhibit a complex vibration response with multiple dominant vibration frequencies that include the …
