“…Relative to this discussion, results showed that the perceptual quality of the clients' post-therapy speech was not improved compared to their pre-therapy speech. Franken et al [10] attributed this latter finding to the fact that only individuals with severe stuttering were used in the study. They suggested that clients with mild stuttering would exhibit a post-therapy improvement in speech quality since they may be able to achieve stutter-free speech without needing to monitor implementation of target behaviors as carefully as clients with a more severe impairment.…”

“…While stuttering is often significantly reduced at the termination of therapy, post-therapy speech has been frequently characterized as slow, monotonous, and lacking in expression [9]. Understandably, it has been suggested that, not only the reduction of stuttering but also, the residual quality of the post therapy speech (i.e., 'natural-sounding speech') be as a goal of stuttering treatment [10][11][12][13].…”

The effect of therapy and altered auditory feedback (AAF) on the perception of speech naturalness of people who stutter was examined. Thirty-five naïve young adult listeners rated speech samples from fluent speakers and individuals who stutter. Samples came from normal adults who spoke Standard American English; adults with mild or severe stuttering who spoke under conditions of non-altered feedback (NAF), delayed auditory feedback (DAF), and frequency-altered feedback (FAF); and adults with mild or severe stuttering prior to and following successful completion of a Precision Fluency Shaping Program. Speech produced under AAF was rated as significantly more natural sounding than speech from the same individuals under NAF (p < 0.0001). Speech produced during FAF was judged to be more natural sounding than that produced during DAF for those with mild (p = 0.003) and severe (p < 0.0001) stuttering. Mild stuttered speech was judged to have more natural-sounding speech than severe stuttered speech during AAF (p < 0.0001). Speech from individuals following therapy was rated significatly less natural sounding than that from individuals during AAF for both mild and severe stuttering (p < 0.0001). The speech of individuals prior to therapy was rated significantly more natural than their speech produced after therapy (p < 0.0001). Speech from normal fluent speakers was rated as significantly more natural sounding than all samples produced from the individuals who stutter (p < 0.0001). These findings support the contention that AAF benefits those who stutter through a reduction of stuttering with a gain in perceived speech naturalness.

“…This trend is espe cially obvious in the scores of the clinicians and stu t tering listeners. Listeners seem to consider the con trolled fluency and artificial speech technique rather unnatural (Franken et al, 1992). However, at the same time, they tend to accept it for nonformal speaking situ ations and almost accept it for somewhat formal speak ing situations.…”

The purpose of the present study was to develop and evaluate an instrument for assessing the communicative suitability of speech (i.e., the speaking situation-dependent adequacy of speech as judged by listeners). Listeners judged the suitability of speech of people who stutter (N = 10) at three stages of treatment (before, immediately after, and 6 months after) and that of people who do not stutter (N = 10, the latter serving as a reference). The listeners rated the suitability of the speech, using a 10-point scale, for 10 speaking situations that supposedly make different demands, with listeners consisting of three groups: unsophisticated listeners (N = 17), clinicians specializing in the treatment of stuttering (N = 17), and stuttering listeners (N = 17). Results indicate that the rating instrument can be scored reliably. Analysis of variance for the ratings of the reference speakers showed that the factor "situation" had a significant effect on the suitability ratings, with more demanding situations receiving lower suitability scores than the less demanding ones. Also, the speech of the people who stutter was judged significantly less suitable than the speech of the reference speakers. Furthermore, unsophisticated listeners were considerably less tolerant in their judgments than clinicians and stuttering listeners. Findings suggest that communicative suitability is a promising criterion to further investigate, especially as it may apply to the objective evaluation of treatment outcome for stuttering.
