Observed change in mean speaking voice fundamental frequency of two subjects undergoing voice training
David Rossiter, David M. Howard · Logopedics Phoniatrics Vocology · 1997
Previous studies have indicated that trained and untrained voice users exhibit a mean speaking voice fundamental frequency (FO) at a particular percentage point relative to their complete voice FO range. However, as these observations are based on separate groups of subjects, it may be that there are physiological reasons for this. This paper presents a pilot investigation into the relationship between FO and complete voice range. For the study an assessment is made of the mean FO performance of two subjects assessed before, during and after a short course of vocal tuition. It is observed that the mean speaking voice fundamental frequency of both subjects exhibits a generally consistent tendency towards a point at approximately 17% of the total FO range.
