Abstract

In the clinical work with patients in a medical voice clinic it is important to have a normal updated reference for the data used. Several new parameters have to be correlated to older traditional measures. The older ones are stroboscopy, eventually coordinated with electroglottography (EGG), the Multi- Dimensional-Voice Program and airflow rates. Long Time Averaged Spectrograms (LTAS) and phonetograms (voice profiles) are calculating the range and dynamics of tones of the patients. High-speed films, updated airflow measures as well as area calculations of phonotograms add information to the understanding of the glottis closure in single movements of the vocal cords. A multivariate analysis was made to study the connection between the measures. This information can be used in many connections, also in the otolaryngological clinic.
