This paper reviews the development of different kinds of voice range profile measurements from the past to the present stage. The combined measurements of the speakig, shouting, and singing voice range profiles are presented and the methold explained which was developed in Hannover. After analysis of more than 300 persons with normal voices and over 700 patients with voice disorders the relationship between the three voice profiles have been evaluated and described. The voice range profiles may be documented and superimposed for comparison before and after therapy. In functional voice disorders there is often some discrepancy between the singing, shouting, and speaking voice profiles. Despite a normal singing voice profile, the speaking voice area is restricted and displaced. In organic voice disorders the singing voice profile is found more or less reduced particularly in the head register, or all modalities of the voice production are effected. Voice range profile measurements have been proved useful in clinical practice. The method should become more attention for its use in diagnostics and for therapy monitoring in all kinds of voice disorders, exspecially for expert opinion.
