Summary: This Perspectives activity highlights two articles with objective measures for both evaluation and treatment of velopharyngeal dysfunction. The first article discusses the palatal closure efficiency (PaCE) index. This is an aerodynamic tool used to estimate the velopharyngeal opening during certain speech contexts. This is done by measuring a percentage of change between nasal and oral cognates of an individual. The second article describes the nasometer in depth, highlighting its use as an evaluation and treatment tool for decreasing hypernasality. It goes into further detail on the differences between hypernasality and measured nasalance, highlighting both strengths and limitations of the nasalance score.

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: These Perspectives (SIG 5) articles focus on the functional problems caused by the structural anomalies of the craniofacial complex and pathways for intervention. Articles describes the impact of submucous cleft palate, dental/skeletal anomalies, and distraction osteogenesis on speech and resonance outcomes for individuals with craniofacial anomalies. Multidisciplinary roles and best practice recommendations are also provided.

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: These Perspectives (SIG 5) articles focus on the status of academic and clinical training related to cleft and craniofacial conditions, a module training series for addressing the gaps in current educational roadmaps, and resources and best practice recommendations are provided.
