A comparison has been made simultaneously of high speed films, acoustical analysis and overtone analysis with “VoceVista” and “Sygyt Ltd”. The overtones software was compared with acoustical analysis.

The variation of the 3 formants from 1000 Hz-5000 Hz was between 18-25% for normal persons. Glottal analysis tools from Erlangen showed no evidence of traditional acoustical voice analysis. With the new overtone analyzer (Sygyt Ltd.) we have a tool for measuring pathological voices combined with high speed films.
