Stutterers’ Self-Ratings of How Natural Speech Sounds and Feels

Abstract
The efficacy of stuttering treatment has been a contentious issue in recent years. Two issues of primary concern include the treated stutterer’s abnormal speech quality and the problem of continually self-monitoring fluency skills. One approach to addressing these issues is to obtain stutterers’ self-ratings of speech quality and levels of speech monitoring. However, the reliability and validity of such self-ratings need to be assessed before they are suitable for use in stuttering treatment. The present study investigated one method of estimating the reliability and validity of stutterers’ self-ratings of how natural their speech sounds (speech naturalness), and how natural they feel about the amount of attention they are paying to the way they are speaking (feel naturalness). Twelve adult stutterers were instructed to self-rate the speech and feel naturalness of their speech under a variety of rhythmic stimulation conditions across repeated rating occasions. With some qualifications, the results showed that stutterers were relatively consistent and valid self-raters of speech quality and levels of speech monitoring.
