Formant Modification through Vocal Production Learning in Gray Seals.

open access: yesCurrent Biology, 2019
Vocal production learning is a rare communication skill and has only been found in selected avian and mammalian species [1-4]. Although humans use learned formants and voiceless sounds to encode most lexical information [5], evidence for vocal learning ...

Finding the Most Uniform Changes in Vowel Polygon Caused by Psychological Stress [PDF]

open access: yes, 2015
Using vowel polygons, exactly their parameters, is chosen as the criterion for achievement of differences between normal state of speaker and relevant speech under real psychological stress.

Waveguide physical modeling of vocal tract acoustics: flexible formant bandwidth control from increased model dimensionality [PDF]

open access: yes, 2006
Digital waveguide physical modeling is often used as an efficient representation of acoustical resonators such as the human vocal tract. Building on the basic one-dimensional (1-D) Kelly-Lochbaum tract model, various speech synthesis techniques ...

Corner vowels in males and females ages 4 to 20 years: Fundamental and F1-F4 formant frequencies.

open access: yesJournal of the Acoustical Society of America, 2019
The purpose of this study was to determine the developmental trajectory of the four corner vowels' fundamental frequency (fo) and the first four formant frequencies (F1-F4), and to assess when speaker-sex differences emerge.

F0-induced formant measurement errors result in biased variabilities.

open access: yesJournal of the Acoustical Society of America, 2019
Many developmental studies attribute reduction of acoustic variability to increasing motor control. However, linear prediction-based formant measurements are known to be biased toward the nearest harmonic of F0, especially at high F0s.

Field Propagation Experiments of Male African Savanna Elephant Rumbles: A Focus on the Transmission of Formant Frequencies

open access: yesAnimals, 2018
African savanna elephants live in dynamic fission–fusion societies and exhibit a sophisticated vocal communication system. Their most frequent call-type is the ‘rumble’, with a fundamental frequency (which refers to the lowest vocal ...

Low frequency groans indicate larger and more dominant fallow deer (Dama dama) males. [PDF]

open access: yesPLoS ONE, 2008
BACKGROUND: Models of honest advertisement predict that sexually selected calls should signal male quality. In most vertebrates, high quality males have larger body sizes that determine higher social status and in turn higher reproductive success ...

Exploring auditory-motor interactions in normal and disordered speech [PDF]

open access: yes, 2013
Auditory feedback plays an important role in speech motor learning and in the online correction of speech movements. Speakers can detect and correct auditory feedback errors at the segmental and suprasegmental levels during ongoing speech.

Jak badać samogłoski metodami akustycznymi?

open access: yesLingVaria, 2014
How to study vowels using acoustic methods? A proposal of a method based on relative formant frequencies and the cardinal vowels model The first part of the paper proposes a method of studying (or, more precisely, of recognizing) oral vowels, using ...

Changes in salivary estradiol predict changes in women’s preferences for vocal masculinity [PDF]

open access: yes, 2014
Although many studies have reported that women’s preferences for masculine physical characteristics in men change systematically during the menstrual cycle, the hormonal mechanisms underpinning these changes are currently poorly understood.
