Abstract : Ten subjects monitored five speech samples at five different levels of intensity. Each subject was required to watch the Volume Unit (VU) meter, listen to the spoken material and set an average level for recording what was heard. Five of the subjects had considerable experience with audio equipment and formed the trained group; the other five subjects had no familiarity with sound recording instruments and formed the untrained group. There were no differences in the monitoring of vocal intensity between the trained and untrained groups with respect to Mean Performance level and variability. Training did not affect performance scores at the different intensity levels. Performance scores on different reading passages were significantly different for the trained and untrained groups. The trained group was less variable than the untrained group from one passage to another. (Author)
