Speech Adaptation to Kinematic Recording Sensors: Perceptual and Acoustic Findings
Conclusion The findings suggest that 10 min may be sufficient time to allow speakers to adapt before experimental data collection with Northern Digital Instruments Wave electromagnetic sensors. (Source: Journal of Speech, Language, and Hearing Research)

Poor Speech Perception Is Not a Core Deficit of Childhood Apraxia of Speech: Preliminary Findings
Conclusions These findings suggest that speech perception deficits are not a core feature of CAS but rather occur with co-occurring language impairment in a subset of children with CAS. This study establishes the significance of accounting for language ability in children with CAS.Supplemental Materialshttps://doi.org/10.23641/asha.5848056 (Source: Journal of Speech, Language, and Hearing Research)

Statistical Methodology for the Analysis of Repeated Duration Data in Behavioral Studies
Conclusions We provide methods to select the best-fitting models for repeated duration data and to compare statistical methodologies. In this study, we show that Cox models are best suited to the analysis of our data set. (Source: Journal of Speech, Language, and Hearing Research)

Development of Velopharyngeal Closure for Vocalization During the First 2 Years of Life
Conclusion Velopharyngeal closure for spontaneous speech production can be considered complete by 19 months, but closure occurs earlier for speech sounds with higher oral pressure demands. (Source: Journal of Speech, Language, and Hearing Research)

Dysarthria in Mandarin-Speaking Children With Cerebral Palsy: Speech Subsystem Profiles
Conclusion Children with CP demonstrated deficits in speech intelligibility and articulation compared with TD children. Better speech sound articulation influenced higher word intelligibility, but did not benefit sentence intelligibility. (Source: Journal of Speech, Language, and Hearing Research)

Deep Brain Stimulation of the Subthalamic Nucleus Parameter Optimization for Vowel Acoustics and Speech Intelligibility in Parkinson's Disease
Conclusions Although lower-frequency STN-DBS stimulation was found to yield consistent improvements in speech outcomes, it was not found to necessarily lead to the best speech outcomes for all participants. Nevertheless, frequency may serve as a starting point to explore settings that will optimize an individual's speech outcomes following STN-DBS surgery.Supplemental Materialhttps://doi.org/10.23641/asha.5899228 (Source: Journal of Speech, Language, and Hearing Research)

Pitch and Time Processing in Speech and Tones: The Effects of Musical Training and Attention
Conclusion In general, this experiment shows that individuals with a better sense of pitch discrimination also have a better sense of timing discrimination in the auditory domain. In addition, although musicians perform better overall, these results do not support the idea that musicians have an added advantage for divided attention tasks. These findings serve to better understand how musical training and attention affect pitch and time processing in the context of speech and tones and may have applications in special populations.Supplemental Materialhttps://doi.org/10.23641/asha.5895997 (Source: Journal of Speech, Languag...

Vocalization Subsystem Responses to a Temporarily Induced Unilateral Vocal Fold Paralysis
Conclusions Group data alone masked important variability necessary to understand the unique relationships among the 3 subsystems. Multilevel analysis permitted a richer understanding of the individual differences in phonatory regulation and permitted subgroup analysis. Dynamic systems theory may be a useful heuristic to model the interactive relationships among vocalization subsystems.Supplemental Materialhttps://doi.org/10.23641/asha.5913532 (Source: Journal of Speech, Language, and Hearing Research)

Acoustic Predictors of Pediatric Dysarthria in Cerebral Palsy
Conclusion This study serves as a first step toward developing an acoustic model that can be used to improve early identification of dysarthria in children with CP. (Source: Journal of Speech, Language, and Hearing Research)

Tutorial and Guidelines on Measurement of Sound Pressure Level in Voice and Speech
Conclusions SPL of voice and speech should be reported together with the mouth-to-microphone distance so that the levels can be related to vocal power. Sound level measurement settings (i.e., frequency weighting and time weighting/averaging) should always be specified. Classified sound level meters should be used to assure measurement accuracy. Head-mounted microphones placed at the proximity of the mouth improve signal-to-noise ratio and can be taken advantage of for voice SPL measurements when calibrated. Background noise levels should be reported besides the sound levels of voice and speech. (Source: Journal of Speech, ...

Listeners Experience Linguistic Masking Release in Noise-Vocoded Speech-in-Speech Recognition
Conclusion The current study is the first to report a clear LRM benefit in noise-vocoded speech-in-speech recognition. Our results indicate that this benefit is available even under spectrally degraded conditions and that it may augment the benefit due to spatial separation of target speech and competing backgrounds.

The Effect of Remote Masking on the Reception of Speech by Young School-Age Children
Conclusions In accord with psychoacoustic data, young children do not appear to focus on a spectral region of interest and ignore other regions during speech recognition. This tendency may help account for their typically poorer speech perception in noise. This study also appears to capture an important developmental stage, during which a substantial refinement in spectral listening occurs. (Source: Journal of Speech, Language, and Hearing Research)

Performance on Auditory and Visual Tasks of Inhibition in English Monolingual and Spanish –English Bilingual Adults: Do Bilinguals Have a Cognitive Advantage?
Conclusions No significant differences in performance on auditory and visual tests of inhibition of irrelevant information were evidenced between the monolingual and bilingual participants in this study. These findings suggest that bilinguals may not exhibit an advantage in the inhibition of irrelevant information compared with monolinguals. (Source: Journal of Speech, Language, and Hearing Research)

Remote Microphone System Use at Home: Impact on Caregiver Talk
Conclusions Findings from this investigation suggest that children with hearing loss have increased access to caregiver talk when using an RMS in the home environment. Clinical implications and future directions for research are discussed. (Source: Journal of Speech, Language, and Hearing Research)
