“…Only recently has a cosmetically appealing self-contained ear-level device delivering AAF for the application with those who stutter been achieved [50]. This device incorporates a microdigital signal processor core that reproduces the high fidelity of unaided listening and auditory self-monitoring while at the same time delivering DAF and FAF signals in combination or isolation in a custom in-thecanal or completely in-the-canal design.…”

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.

“…Research about MAF has not been reviewed because of the decline in interest in this condition. Increasingly sophisticated and miniaturized devices capable of providing DAF and FAF have become commercially available to clinicians and people who stutter (Stuart, Xia, Jiang, Kalinowski, & Ratstatter, 2003). Information can be found on the world-wide web about 12 different commercially available portable devices providing FAF, DAF or a combination of both (see Table 1 for summary of devices).…”
