A number of experiments were made in the field of speech diagnostic analysis in which researchers wanted to examine whether it was the acoustic characteristics of sustained voice or continuous speech that were more appropriate for distinguishing healthy from pathological voice. While in phoniatric practice, doctors mainly use continuous speech, we also wanted to concentrate on the examination o...

vocal fatigue is a voice symptom which is frequently reported by professional voice users. teachers, singers, actors and other professions that require prolonged voice use are especially at-risk group. the vocal fatigue results in auditory perceptual and acoustic changes in the voice signal and can lead to serious pathological conditions. the present study has examined acoustic manifestations o...

Aim of this investigation was to analyse the voice in a group of 20 patients submitted to supracricoid partial laryngectomy (cricohyoidopexy, sparing two arytenoids) by the Multi Dimensional Voice Programme acoustic analysis system. Results revealed the following sound characteristics: high rate of noise, lack of periodic component of the signal, high rate of segments with no sound signal, voca...

Muscle tension dysphonia (MTD) is a voice disorder that occurs as a result of misuse or abuse of the voice [1]. While there is no neurological damage to the larynx nor any structural abnormality present, patients with MTD have limitations in vocal vibrations due to laryngeal muscle tension. Consequently, such patients demonstrate pathological voice problems, such as hoarseness, strained and str...

BACKGROUND Because of advances in voice research, voice acoustic analysis including fundamental frequency (F0), sound pressure level (SPL), jitter, shimmer, harmonics-to-noise ratio (H/N ratio), and maximum phonation time (MPT) can now be easily recorded and analyzed with a computer. Because these systems are widely used in clinical practice, this study was designed to establish the normal acou...

This paper describes a study of speaking-style characteristics, or “tone-of-voice”, in conversational speech, and shows that non-verbal information is transmitted efficiently regardless of cultural and linguistic contexts through differences in prosodic and voice-quality features. We asked Korean and American listeners with no previous kowledge of Japanese to judge the meaning of various uttera...

BACKGROUND Persons with stuttering (PWS) often present with other co-occurring conditions. The World Health Organization's (WHO) International Classification of Functioning, Disability and Health (ICF) proposes that it is important to understand the full burden of a health condition. A few studies have explored voice problems among PWS, and the characteristics of voices of PWS are relatively un...

We conducted a comparative study of a voice produced by a professional impersonator imitating a target speaker to explore the acoustical characteristics that the impersonator changes from his natural voice to imitate a target voice. Comparison of the pitch frequency of the target and imitated voices showed that the mean and dynamics of the pitch frequency of the imitated voice are changed so th...
