Research on links between peoples’ personality traits and their voices has primarily focused other judgments about a target person based person’s vocal characteristics, particularly voice pitch. However, it remains unclear whether individual differences in are linked to actual traits, thus characteristics indeed valid cues personality. Here, we investigate how the of Five Factor Model Personali...

This study explored two tenets of the Italian Bel Canto operatic singing technique “Come si parla” and “aggiustamento.” Articulatory changes in the lower formant vowel space of 11 spoken and sung vowels were systematically examined in six male singers. Results showed that singers influence the placement of the lowest formant frequencies in the sung vowel space using both a lowered larynx and mo...

It is shown that within-speaker variations in vocal effort and phonation affect fundamental frequency (F0) and the formant frequencies of vowels in the sense of a linear compression/expansion of the spectral separations between them, given an adequate scaling of pitch. Between-speaker variations in size correspond to a translation of the spectral peaks shaped by F0 and the formants if pitch is ...

Body weight, length, and vocal tract length were measured for 23 rhesus macaques (Macaca mulatta) of various sizes using radiographs and computer graphic techniques. linear predictive coding analysis of tape-recorded threat vocalizations were used to determine vocal tract resonance frequencies ("formants") for the same animals. A new acoustic variable is proposed, "formant dispersion," which sh...

this paper reports the results of an experimental study on non-native production of english vowels. two groups of persian efl learners varying in language proficiency were tested on their ability to produce the nine plain vowels of american english. vowel production accuracy was assessed by means of acoustic measurements. ladefoged and maddison’s (1996) f1 f2 measurements for american english v...

We conducted quantitative analyses of a magnetic resonance imaging (MRI) database to examine the correlation between physical measures (vocal tract length and body height) and acoustic parameters (pitch and formant frequencies) of vowels. The vocal tract length was measured from MRI data for the five Japanese vowels produced by fifteen male Japanese speakers between the ages of 24 and 55. The a...

Formants are important phonetic elements of human speech that are also used by humans and non-human mammals to assess the body size of potential mates and rivals. As a consequence, it has been suggested that formant perception, which is crucial for speech perception, may have evolved through sexual selection. Somewhat surprisingly, though, no previous studies have examined whether sexes differ ...

This paper proposes a real-time variable-Q non-stationary Gabor transform (VQ-NSGT) system for speech pitch shifting. The system allows for time-frequency representations of speech on variable-Q (VQ) with perfect reconstruction and computational efficiency. The proposed VQ-NSGT phase vocoder can be used for pitch shifting by simple frequency translation (transposing partials along the frequency...

this study focuses on one particular sound change common in conversational speech, in which coronal nasal consonants undergo place assimilation toward the following syllable- or word-initial labial consonants. f2 and f3 formant frequency measurements were taken from, and compared between words involving the sequences /vnb/ and /vmb/ across syllable boundary as well as word boundary in assimilat...
