Summary: These articles show the breadth of topics relevant to the understanding and treatment of fluency and fluency disorders. The articles include topics on the impact of allergies on the sleep of children who stutter and using solution-focused principles to elicit perspectives on therapeutic change in older children who stutter and their parents.

Summary: This activity is a grouping of studies related to the understanding stuttering throughout the life span. The activity is based on articles related to attentional focus on motor control in people who stutter (PWS) and the relationship to social stress, acoustic measures of emotion in children who stutter, a study of covert stuttering throughout the lifespan, vocational stereotyping of PWS by human resource preprofessionals, and audio-based podcasts to assist in self-help for PWS. Together, these articles investigate important measures in understanding stuttering and how researchers and clinicians can better understand the condition of stuttering.

Summary: This activity presents a diverse perspective, including four different speech science articles focused on a variety of topics. Kimball and Sayce discuss the pros and cons of research using behavior and functional assessment and treatment in the areas of speech science and voice, specifically their limitation in outlining etiology or explaining treatment resistance. They also provide an overview of genetic research approaches as a possible path forward to develop additional evidence-based treatment approaches. Neel reviews the production and perception of extralinguistic information regarding sex/gender, sexual orientation, age, non-native accent, regional and social dialect, and race and ethnicity. The article explores the literature in the above areas reviewing acoustical features and common misperceptions, concluding with instructional activities to enhance student awareness of indexical characteristics. McAllister et al. studied the effects of biofeedback for residual rhotic errors in a preliminary case series. Participants were five native English speakers who had not yet generalized rhotic production. Treatment consisted of either electropalatographic or visual-acoustic biofeedback using the Challenge Point Program software. Although participant responses to treatment were variable, the median effect size tended to exceed the minimum value considered clinically significant. Gritsyk et al. examined three measures to determine which best predicted change in production accuracy during a vowel learning task. Using 20 female college students, researchers administered three tasks: an oral stereognosis task, a bite block task using auditory making, and a new phonetic awareness task. The bite block task with auditory masking, measuring proprioceptive awareness, was the only task significantly related to performance in speech learning.

Summary: This Perspectives (SIG 19) includes four different speech science articles that focus on speech production, speech perception, or both. Akbari and Aoyama examine epenthetic vowels produced by Persian L2 speakers of English corroborating previous research findings regarding acoustical characteristics of anaptyctic epenthetic vowels—prothetic epenthetic vowels differ from the phonemic vowels they precede. Hitchcock et al. examine speech perception of typical adults, typical children, and children with speech sound disorders, finding that children with speech sound disorders differ as compared to both typical groups. Rong conducted a preliminary examination of the articulatory control of speech and speech-like tasks. The results revealed shared and task-specific articulatory features in speech and speech-like tasks, specifically sharing that alternating motion rate tasks may be more useful for assessing temporal aspects of articulation whereas sequential motion rate tasks may be more useful for assessing spatial aspects of articulation and coordination. Lastly, Boyd-Pratt and Donai review evidence that the high frequency region contains perceptual cues regarding segmental, speaker identity, and speaker sex as well as improved speech recognition in the presence of noise.

Summary: In these Perspectives (SIG 4) articles, two of the articles relate to patterns of disfluency in young bilingual children—one of these two articles adds the patterns of stuttering in young bilingual children that stutter. The third article uses a thematic analysis to help understand why adults who stutter attended self-help groups.

Summary: These Perspectives (SIG 19) articles focus on perceptual considerations and the use of a system to investigate lingual coordination as a clinical tool. In the first article Rakerd et al. review the resonant effects of performers, resonance associated with nasality, and resonant voice for both normal and disordered populations. In the second article Grover et al. use the bubble noise method, which places noise randomly in time and frequency with “holes” or “bubbles” that give glimpses into the target signal, to determine what is perceptually important in the speech signal for native/first language listeners versus nonnative/second language listeners. In the final article, Dugan et al. review TonguePART, an image processing system used to track the tongue surface, as a reliable, fast method to track articulatory movement of the tongue for syllables
