After training, i.e. after mimicking early phases of speech acqui- sition, the model is capable of producing and per- ceiving vowels and CV-syllables (C = voiced plo- sives). Different instances of the model were trained for representing different "virtual subjects" which are then used as listeners in identification and

It was the aim of the present study to combine the two examinations, in order to estimate the relationship between pitch, sound pressure level and voice duration and to develop a new computer-assisted graph. A three-dimensional (3D) wireframe phonogram was constructed based on SPL profiles to obtain a general view of the parameters recorded. We have termed this "phonetography". Variable further projections were selected for the analysis of different aspects of parametric relationships. The results in 21 healthy volunteers and 4 patients with hyperfunctional dysphonias demonstrated that there were three typical figures of the 3D phonograms produced, depending on the relationship between voice duration when soft ("piano") compared to loud ("forte"). In one-third of the healthy volunteers, the values of the piano voice duration were greater than those of forte for almost all pitches examined. In two-thirds of the healthy subjects the values of forte voice duration were partly greater, as were those of piano voice duration. All of the patients showed voice duration values greater for forte than for piano. The results of the study demonstrate that the 3D phonogram is a useful tool for obtaining new insights into various relationships of voice parameters.

They are usually connected with damage to the central nervous system, thus being combined with further neurological symptoms. In German and English literature 9 cases of isolated statoacoustic nerve lesions due to vaccinations could be found. They are summarized and their similarities and differences are discussed. Information relevant for the evaluation of possible causal relations between vaccinations and solitary 8th cranial nerve disorders is emphasized. Questions concerning the incidence, etiology and differential diagnosis of functional cochleovestibular impairments are highlighted.

With one exception all participants were treated with intramuscular application of testosterone. Our data were based on phoniatric examinations, comprehensive interviews, an examination of gender attribution by independent listeners and acoustical voice analysis. The results revealed non-uniform gender attribution predominantly for participants with testosterone treatment less than one year. Impaired performance concerning voice intensity, voice quality and upper border of singing range were found independently of the duration of testosterone application. We conclude that voice therapy seems to be advisable for female-to-male transgenders. Until the end of the first year of hormone therapy voice care should be focused upon gender-related voice performance. Vocal efficiency in relation to individual demands is of major importance after this period.
