Objectives: Voice is influenced by personality. However, it is still questionable which acoustic features are influenced by personality traits. This study aimed to investigate the relationship between acoustic characteristics and personality dimensions. Methods: Thirty-three participants with dysphonia and 33 participants without dysphonia were recruited to take part in this cross-sectional st...

This study investigates the production of Brazilian Portuguese (BP) vowels by subjects with hypokinetic dysarthria. Twelve subjects participated in the study, including six who had hypokinetic dysarthria, and six without any neurological disorders or speech disturbance. The data consist of the first two formant frequency values for the samples of the seven vowels in BP. Analyses were performed ...

In speech articulation, mouth/lip shapes determine properties of the front part of the vocal tract, and so alter vowel formant frequencies. Mouth and lip shapes also determine facial emotional expressions, e.g., disgust is typically expressed with a distinctive lip and mouth configuration (i.e., closed mouth, pulled back lip corners). This overlap of speech and emotion gestures suggests that ex...

We used magnetoencephalography to investigate auditory evoked responses to speech vocalizations and non-speech tones in adults who do and do not stutter. Neuromagnetic field patterns were recorded as participants listened to a 1 kHz tone, playback of their own productions of the vowel /i/ and vowel-initial words, and actively generated the vowel /i/ and vowel-initial words. Activation of the au...

Vowel space area (VSA) refers to a two-dimensional area, which is bounded by lines joining F1and F2 coordinates of vowels. In the speech of individuals with cleft lip and palate (CLP), the effect of hypernasality introduces the pole-zero pairs in the speech spectrum, which will shift the formants of a target sound. As a result, vowel space in hypernasal speech gets affected. In this work, analy...

Czech vowels in fluent speech and their parameters can be found by The Generation and Analysis of Vowel Polygons software. On the base of found vowels formant values, vowel polygons can be created and further analyzed as a unit in relevant formant planes. Phoneme recognition is based on pattern similarity using Mahalanobis distance and Feed-forward Neural Network, and it is expanded by time dur...

Two phoneme monitoring experiments examined the influence of Transitional Probability (TP) on phoneme recognition. Target phonemes appeared at the end of Consonant-Vowel-Consonant (CVC) syllables, or as the first element of coda clusters in CVCC syllables. Reliable TP effects were found only for targets in CVCC syllables. The TPs both into and out of the targets influenced listeners' ability to...

This paper discusses issues including tongue position, tongue movement space, constraint etc. of Mongolian word-initial consonants. The experimental result shows that word-initial consonant tongue horizontal movement space is constrained by constriction position and is in conformity with the rule that front consonant leads to smaller tongue movement space; higher consonant leads to smaller tong...
