Thirty females and 25 males with normal voice participated in the study. The Pearson correlation coefficient was determined through a statistical analysis. The results came out as follows; Firstly, there was a correlation between $F_0$ and voice quality parameters, however there was no correlation between $F_0$ and nasalance. Secondly, nasalance showed a correlation with voice quality parameters.
