This paper investigates various aspects of intonation and phonation in young adults with Down syndrome. The speech of nine speakers with Down syndrome was analyzed acoustically for different aspects of intonation and phonation. The results of these analyses were compared to similar speech samples of nine typical speakers of Standard British English. The controls were matched for age and gender....

Pitch period and amplitude perturbations are widely used parameters to discriminate normal and voice disorder speech. Instantaneous pitch period and amplitude of glottal vibrations directly from the speech waveform may not give an accurate estimation of jitter and shimmer. In this paper, the significance of epochs (glottal closure instants) and strength of excitation (SoE) derived from the zero...

The author describes aesthetic and practical considerations involved in the integration of sound and image in two recent compositions for piano and computer. In the first of these works, Shimmer (2004), video imagery is derived from the work’s sonic materials while in the second, Canon (2005), visual canons are generated from the real-time movement of the pianist’s hands. The author describes e...

Objective Today transoral laser microsurgery is considered as one of the first options to control early laryngeal cancer, and voice disorder inevitable complications this therapeutic component. This study aimed compare vocal function in patients with early-stage cancer following surgery healthy individuals normal quality using acoustic analysis handicap index examine correlation between results...

PURPOSE To analyze the impact of body weight and body fat volume on selected parameters of vocal quality, phonatory range, and aerodynamics in females. METHODS Based on measurements of body mass index in combination with body fat volume, 29 normophonic female subjects were classified as normal weight, underweight, and obese. Voice quality was investigated via auditory-perceptual ratings of br...

OBJECTIVES To compare voice parameters in subjects with different hearing level. METHODS The evaluation consisted of Multi-Dimensional Voice Program (MDVP) and electroglottography. Group 1 consisted of normal hearing subjects which is bilateral average hearing better than 25 decibels (dB) whereas group 2 consisted of patients who have bilateral average hearing between the 25 and 60 dB and gro...

Temperature and head movement are relevant parameters when analyzing the farrowing behavior of sows. Obtaining these body parameters in a way that is nonintrusive to animals is a major challenge in the harsh farrowing pen environment. Due to the presence of large amounts of metal as well as the unpredictable behavior of animals, such environments are not ideal for wired communication platforms....

Objectives: To investigate the validity of cepstral analyses against other conventional acoustic measures of voice quality in determining the perceptual impression in different motor speech disorders hypokinetic and ataxic dysarthria, and speech tasks prolonged vowels and connected speech. Methods: Prolonged vowel productions as well as connected speech samples (reading passages and monologues)...

BACKGROUND/AIMS Frequency and amplitude perturbations are inherent in voice acoustic signals. The assessment of voice perturbation is influenced by several factors, including the type of recording equipment used and the measurement extraction algorithm applied. In the present study, perturbation measures provided by two computer systems (a purpose-built professional voice analysis apparatus and...

The influence of pitch contour, segmental durations, and spectral features on the perception of two speaking styles was studied. For this purpose two male speakers each spoke “spontaneously” to an interviewer and afterwards read out their own literally transcribed spontaneous text. Pairs of identical spontaneous and read utterances were selected that were fluently spoken in both speaking styles...
