Encoding voice fundamental frequency into vibrotactile frequency

The Journal of the Acoustical Society of America, 1979
Measured in this study was the ability of eight hearing and five deaf subjects to identify the stress pattern in a short sentence from the variation in voice fundamental frequency (F0), when presented aurally (for hearing subjects) and when transformed into vibrotactile pulse frequency.

Frequency Code: Orofacial Correlates of Fundamental Frequency

Phonetica, 1987
Abstract In the human voice, lip retraction as in smiling can be associated with high fundamental (F₀) and formant frequencies. The aim of this study was to investigate under naturalistic conditions the cross-species generality of the frequency code hypothesis and related orofacial correlates in F₀.

Fundamental-frequency approximation methods

The Journal of the Acoustical Society of America, 1974
The vibration of a sandwich plate is used, as an illustrative problem, to evaluate the effectiveness of some methods of obtaining one-term approximations for the lowest eigenvalue of coupled systems. It is shown that, in using a method of weighted residuals, the boundary conditions satisfied by both the trial and the weighting function play significant

Fundamental Frequency Estimation

1976
The fundamental frequency (F0) is a basic parameter in acoustical studies of speech. It is also a necessary parameter for low bit rate speech coding systems. It is generally considered to be one of the acoustical correlates to the perceived intonation pattern of speech.

Redefinition of Fundamental Frequency

The Journal of the Acoustical Society of America, 1962
Fundamental frequency of normal and esophageal utterances was measured by (1) number of pulses in a spectrographic continuous-amplitude display, (2) number of cycles in an oscillographic wavetracing, (3) harmonic interval in a narrow-band spectrogram. The results obtained by these measures yield widely varying fundamental frequencies.

Two-voice fundamental frequency estimation

The Journal of the Acoustical Society of America, 2002
An algorithm is presented that estimates the fundamental frequencies of two concurrent voices or instruments. The algorithm models each voice as a periodic function of time, and jointly estimates both periods by cancellation according to a previously proposed method [de Cheveigné and Kawahara, Speech Commun. 27, 175–185 (1999)].

Modifying fundamental frequency envelopes

The Journal of the Acoustical Society of America, 1975
An experiment was designed to investigate the hypothesis that changes in fundamental frequency alone are sufficient to cue several readings of a sentence. A sentence was recorded and digitized in four versions and analyzed by a predictor coefficient method. First, the sentence was synthesized with its natural F0 envelope.

Fundamental frequency extracting system

The Journal of the Acoustical Society of America, 1983
A system for extracting the fundamental frequency or pitch of complex waves such as voice, musical instruments or other audio signals. Separate channels extract the fundamental frequency component when it is present in successively wider frequency bands, the frequency intervals between which are equal or less than an octave.

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.

Fundamental frequency contours at syntactic boundaries

The Journal of the Acoustical Society of America, 1977
A series of experiments was conducted to determine the extent to which speakers’ syntactic coding influences fundamental frequency (F0) contours in the region of syntactic boundaries. F0 measurements were obtained for groups of nine and ten speakers by computer using a parallel processing algorithm.
