This study examined the distribution of fundamental frequencies in the connected speech of 14 healthy young adults. Acoustic analysis of fundamental frequency was performed on previously collected speech samples of a phonetically balanced reading passage. For the first three sentences of the reading passage, fundamental frequency contours were extracted using PRAAT, a speech analysis software package. The accuracy of these contours were visually verified and manually corrected when needed. The distribution of the fundamental frequency histories for each sample were then analyzed using Gaussian Mixture Model analyses in MATLAB. For most speakers, four statistical modes were identified in the data ...
