The recordings of 20 speech defective speakers' readings of a standard prose passage were presented to 36 student speech clinicians under three listening conditions: (1) unaltered; (2) time expanded to 150% of the original recording time; and (3) time-expanded to 200% of the original recording time. Results of their evaluations indicate that the expanded versions of the recordings elicited more accurate evaluations by the student clinicians. Implications of these findings concerning the possible usefulness of time-expanded speech as an aid in the training of listening skills in student speech clinicians are discussed.

Correlation coefficients on height, weight, and temporal features were computed separately for 15 female and 15 male speakers. With only one exception, speakers' heights and weights were not significantly correlated with their temporal characteristics. Implications of these findings and suggestions for future research are discussed.

The purpose of this investigation was to determine the relationship among speakers' heights, weights, body surface areas, and speaking fundamental frequencies. The recordings of 30 speakers' readings of a standard prose passage were analyzed by means of the Fundamental Frequency Indicator (FFI) to obtain their speaking fundamental frequency characteristics. The speakers' heights and weights were obtained by means of standard measurement procuedures, and their body surface areas were calculated. Pearson product-moment correlation coefficients, computed separately for men and women, indicated that speakers' heights, weights, and body surface areas were not significantly correlated with their speaking fundamental frequencies; female speakers showed a slight negative correlation while male speakers showed a low, positive trend. Implications of these findings and suggestions for future research are discussed.
