Purpose: The purpose of this study was to thoroughly analyze postoperative consonant errors by tongue cancer (TC) patients with speech disorders and also to investigate the correlation between the pathological factors and the speech performance using our Consonant-based Articulation Assessment Battery (CAAB).

Method: The participants were 57 monolingual Mandarin TC patients (26 women, 31 men) after surgery (aged 20-80 years). All participants were literate and had normal vision and hearing, enabling them to comprehend and comply with our instructions. In order to quickly evaluate their articulation performance based on the place and manner of articulation, they were instructed to pronounce the characters in CAAB. The analysis removed speech samples impacted by speakers' dialects, while recording and documenting all other responses.

Results: The study uncovered a significant correlation between pathological factors (e.g., size of tongue resection, specific resection site, and tumor size) and the accuracy of consonant articulation. Furthermore, tongue damage predominantly impacts the place of articulation (63.85%) than the manner of articulation (20.78%). The damage in the anterior part of the tongue has the most prominent influence on consonant production.

Conclusions: CAAB can fast capture the idiosyncratic characteristics of speech production by TC patients, and the articulation deficits are quite different from other types of organic or nonorganic speech disorders, for example, cleft lip and cleft palate. Hence, CAAB can be designated as an assessment tool for articulation disorders caused by stomatognathic damages. Our findings also shed light on the possible oral cancer surgery plan and the postoperative speech rehabilitation training.

Purpose: The purpose of this study was to examine the influence of socioeconomic deprivation on language and developmental outcomes in toddlers with cleft palate with or without cleft lip (CP ± L). Other factors known to influence language outcomes were also considered, including home language history, history of hearing problems, syndromic diagnoses, and sex.

Method: A multicenter, cross-sectional study design was conducted. Data for 566 16-month-old toddlers with CP ± L were collected from 17 outpatient cleft palate clinics located throughout the United States. Outcome measures included the MacArthur-Bates Communicative Development Inventories, LENA Developmental Snapshot, age at first word as reported by the caregiver, and the Ages and Stages Questionnaires-Third Edition (ASQ-3). Multivariable linear or logistic regression was used to determine the influence of socioeconomic deprivation, as measured by the Area Deprivation Index, on language and developmental outcomes.

Results: Greater socioeconomic deprivation significantly predicted poorer language outcomes in toddlers with CP ± L, including receptive vocabulary words (p = .02), expressive vocabulary words (p = .02), and late-developing gestures (p = .02). Additionally, toddlers from less affluent neighborhoods produced their first words significantly later than their counterparts living in more affluent areas (p < .01). Lower maternal education levels predicted significantly increased risk for problem solving delays (p < .01), and patients with subsidized insurance were at significantly increased risk for personal-social delays on the ASQ-3 (p < .01).

Conclusions: Children with CP ± L are susceptible to developmental delays associated with socioeconomic deprivation. These findings have implications for identifying a child's individual risk factors for developmental language disorders when conducting speech-language assessments. Future study should examine how inequities in care can be mitigated and addressed.

Purpose: The purpose of this study was to investigate the relationship between perceptual ratings of hypernasality made during connected speech and velopharyngeal (VP) gap size measured in millimeters in the sagittal plane during sustained vowel production using magnetic resonance imaging (MRI).

Method: A retrospective cross-sectional analysis was completed. A subgroup of 110 participants from another study with an M_age of 10.1 years presenting for management of VP insufficiency was included. Perceptual ratings of hypernasality during connected speech and measurement of gap size during sustained /i/ production on MRI were performed by raters blinded to the participants' medical and surgical history.

Results: There was a moderate-to-strong, positive correlation (r = .61; p < .001) between hypernasality ratings and VP gap size measured on MRI using sustained /i/. The odds of a higher hypernasality rating increased as the gap size increased (odds ratio = 1.34; 95% CI [1.20, 1.49]; p < .001). The predicted probability for hypernasality ratings of none/minimal/mild steadily decreased as the gap size increased indicating that lower ratings of hypernasality were associated with smaller gap sizes. For the rating of "moderate" hypernasality, the predicted probability of the rating steadily increased up to 8 mm and then decreased as the gap size continued to increase. The predicted probability for a hypernasality rating of "severe" consistently increased as the gap size increased.

Conclusions: Hypernasality ratings made at the connected speech level were significantly associated with VP gap size as measured during sustained vowel production. These findings suggest sustained vowel production elicited on MRI may adequately characterize VP gap size in the evaluation of VP insufficiency.

Purpose: The primary objective of this study was to explore the effects of intensive voice-focused treatment on speech parameters in Spanish speakers with dysarthria associated with Parkinson's disease (PD) as perceived by naïve listeners.

Method: Fifteen Spanish speakers with dysarthria associated with PD received the Lee Silverman Voice Treatment (LSVT LOUD) for a month. Voice and speech recordings were conducted pretreatment, posttreatment, and at a 1-month follow-up. Thirty naïve adult listeners rated the perceptual dimensions of ease of understanding (EoU), resonance, articulatory precision, prosody, and voice quality from sentences extracted from an emotional monologue on a visual analogue scale.

Results: EoU, resonance, articulatory precision, and voice quality significantly improved pre- to posttreatment, but gains were not maintained at follow-up. Speech severity was a significant source of variance in mean listener response for all perceptual dimensions, although the interaction between speech severity and time was only significant for resonance and voice quality.

Conclusions: LSVT LOUD may be beneficial to improve perceptual speech domains affected by PD in Spanish speakers with dysarthria. Its impact on the different speech subsystems may reflect a universal distribution of effects when directly targeting the glottal source. Language-specific contributions of each perceptual domain to speech intelligibility should be explored in further research to determine linguistically sensitive treatment targets.
