Two studies are presented, in which emotional vocal recordings were made using a computer emotion induction task and an imagination technique. Concurrent recordings were made of a variety of physiological parameters, including electroglottograph, respiration, electrocardiogram, and surface electromyogram (muscle tension). Acoustic parameters pertaining to voice quality, including F0 floor, F0 r...

Introduction: Microbubbles are widely used as contrast agent in diagnostic ultrasound. Recently they have shown good potential for applications in the therapeutic field such as drug delivery to the brain. Recent studies have shown focused ultrasound in conjunction with injected micro-bubbles could temporarily disrupt blood-brain barrier and let therapeutic agents transport into...

Traditional didjeridus have a broad range of bore geometries with many details not immediately apparent to a player, and are therefore suitable for examining the relationship between perceived quality and physical properties. Seven experienced players assessed the overall playing quality of 38 didjeridus that spanned a wide range of quality, pitch, and geometry, as well as 11 plastic cylindrica...

In this paper we investigate the modulation domain as an alternative to the acoustic domain for speech enhancement. More specifically, we wish to determine how competitive the modulation domain is for spectral subtraction as compared to the acoustic domain. For this purpose, we extend the traditional analysis-modification-synthesis framework to include modulation domain processing. We then comp...

A data transmission framework is proposed to embed digital data into an audio signal in a perceptually undetectable or almost undetectable way. The resulting signal can be reproduced as is with no loss of acoustic quality; the embedded data can be exactly retrieved at the decoder. The transmission process exploits the perceptual redundancy of the audio signal to conceal the acoustic impact of t...

Data hiding in audio signal enables acoustic data transmission by playing back the data-embedded audio and by recording the signal and extracting the data at receiver like mobile devices. In our previous work, we proposed an audio data hiding system for acoustic data transmission, of which the audio quality and transmission performance are suitable, based on phase modification of the modulated ...

An acoustic analysis of voice, articulatory, and prosodic cues to perceived age was completed for a speech database of 150 American English speakers. Perceived ages were submitted to multiple linear regression analyses with measures of acoustic correlates of: voice quality, articulation, fundamental frequency, and prosody. The fit between predicted and actual perceived ages from the resulting m...

Low loss Bulk Acoustic Wave devices are considered from the point of view of the solid state approach as phonon-confining cavities. We demonstrate effective design of such acoustic cavities with phonon-trapping techniques exhibiting extremely high quality factors for trapped longitudinally-polarized phonons of various wavelengths. Quality factors of observed modes exceed 1 billion, with a maxim...

This paper presents high-level strategies for controlling emotional speech morphing algorithms. Emotion morphing is realized by representing the acoustic features in their timefrequency plan that is warped and modified to generate natural morphed emotional speech. These acoustic features are desirable to be decomposed into multidimensional space and to be orthogonal. After matching these acoust...
