The Voice and Speech Quality Correlates of Psychological Observations in Jungian Active Imagination Experiment.

Jungian active imagination is a well known and valuable method in analytical psychology and psychotherapy. The present study assessed, for the first time, psychological and psycho-acoustical (voice and speech quality) effects of active imagination experiment in outdoor, forest, ambient. In order to analyse the voice and speech quality, participants' verbal expressions were recorded before and after the experiment.

Hetero-aggressive outbursts in patients' behaviour in emergency psychiatry.

Introduction: Hetero-aggressive behaviour in patients with mental disorders is frequent and requires special skills of doctors and other medical staff in order to urgently protect the patient and indicate hospitalization.

Objective: The objective of this paper was to examine the frequency of the most common diagnostic categories in psychiatric patients with hetero-aggressive behaviour. The secondary objective was to examine aspects of realized hospitalization (voluntary, involuntary) and socio-demographic characteristics of these patients.

Adaptive filter based two-probe noise suppression system for transient evoked otoacoustic emission detection.

Transient otoacoustic emission (TEOAE) is a method widely used in clinical practice for assessment of hearing quality. The main problem in TEOAE detection is its much lower level than the level of environmental and biological noise. While the environmental noise level can be controlled, the biological noise can be only reduced by appropriate signal processing.

Production and perception of distortion in word-initial friction duration.

Unlabelled: The purpose of the present study was to investigate (a) the distortion in production of word-initial friction duration in fricative //, and (b) the perceptual discrimination between typical (normal) and atypical (prolonged or lengthened) friction duration. In the first experiment 80 school aged children pronounced word /uma/, 40 of them have had typical friction duration, 15 shortened and 25 lengthened duration of //, and all of them did not have any distortion in segment /uma/. Measurement and analysis of duration of both segments // and /uma/ were performed after segmentation of speech stimuli /uma/.

Adaptive microphone array for unknown desired speaker's transfer function.

The main drawback of minimum variance distortionless response (MVDR) beamformer is the cancellation of the desired speech signal and its degradation in multi-path wave propagation environment. To make the adaptive algorithm robust against room reverberation and to prevent desired signal cancellation an estimation of unknown desired speaker's transfer function was proposed. The estimation is based on the signal and the interference covariance matrices.

Acoustic analysis of consonants in whispered speech.

An acoustic analysis of whispered consonants in comparison to normally phonated consonants was conducted in time and intensity domains. Consonant duration and average root mean square intensity were measured for six speakers in both articulation modes. Each of 25 Serbian consonants (C) was sited between the vowel /a/ forming a syllable of /aCa/ type.
