Two experiments are reported in which the magnitude of sampling errors associated with estimates of the mean, median, and standard deviation of voice fundamental frequencies (fo) during oral reading is investigated as a function of sample size. In one experiment, voices are sampled with fixed time windows. In the other experiment, results of fo analysis are compared for single-sentence voice samples and paragraph voice samples. Overall shape of fo distributions as well as interrelationships among various distributional measures are discussed.
