Formant-Frequency Variation and Its Effects on Across-Formant Grouping in Speech Perception
2013How speech is separated perceptually from other speech remains poorly understood. In a series of experiments, perceptual organisation was probed by presenting three-formant (F1+F2+F3) analogues of target sentences dichotically, together with a competitor for F2 (F2C), or for F2+F3, which listeners must reject to optimise recognition.

Formant frequency development: 15 to 36 months
Journal of Voice, 1997Developmental characteristics of formant 1 (F1) and formant 2 (F2) are reported for spontaneous vocalizations produced by four young children. Each child was systematically sampled at between 15 and 36 months of age. Results indicated that both F1 and F2 remained relatively unchanged prior to 24 months of age. Significant decreases in average F1 and F2

Modeling formant frequency discrimination of female vowels
The Journal of the Acoustical Society of America, 1996The present investigations were designed to establish the features of vowel spectra that mediate formant frequency discrimination. Thresholds for detecting frequency shifts in the first and second formants of two steady-state vowels were initially measured for conditions in which the amplitudes of all harmonics varied in accordance with a model of ...

The role of fundamental frequency and formants in voice gender identification
Speech, Language and Hearing, 2014AbstractPurposeThe present study examined how fundamental frequency (F0) and formant frequencies contribute to the identification of gender.MethodSpeech stimuli were synthesized from recorded voices of men and women using a formant scaling factor of 1.2 and F0 range of 100–250 Hz. Listeners who were native speakers of Cantonese were instructed to judge

Formant frequency patterns in Russian VCV utterances
The Journal of the Acoustical Society of America, 1979Previous studies have sought to establish the significance of various parameters in the determination of the patternings of Russian formant frequency trajectories in vowel-consonant-vowel (VCV) syllables. In the present study, 9600 measurements of first and second formant frequency were made on Russian VCV nonsense words.

A Difference Limen for Vowel Formant Frequency
The Journal of the Acoustical Society of America, 1955Experiments have been conducted to determine difference limens (DL's) for vowel formant frequency. The DL's are obtained from quality judgments on synthetic vowel sounds. The results indicate the maximum accuracy necessary in analyzing the formant structure of spoken vowels and in synthesizing the sounds from the resulting formant data.
