“…A spline was fitted to indicate the surface of the tongue using semi-automatic edge detection from the AAA software, which has recently been validated as a reliable method for tracking ultrasound tongue images. 13 If small corrections were required, they were retraced manually using the AAA “snap-to-fit” function.…”

“…Until recently this has been a time-consuming process, with annotators drawing lines on the images by hand. This problem is now largely solved with automatic tracking available, 13 in some cases, including estimation of the tip of the tongue's position. 14 A small number of studies have used UTI for measuring articulation in speakers with CP+/-CL.…”

Objective This study aimed to determine whether increased raising of the back of the tongue is evident in children with repaired cleft palate with or without cleft lip (CP+/-CL). We hypothesized that children with CP+/-CL would show increased raising of the tongue dorsum, a compensatory pattern. Method Secondary data analysis of mid-sagittal ultrasound tongue imaging data from 31 children with CP+/-CL and 29 typically developing children were used. We annotated the consonants /ʃ, t, s, k/ at the point of maximum constriction in an /aCa/ environment. Children with CP+/-CL said the tokens 10 times, typically developing children said them once. We automatically fitted splines to the tongue contour and extracted the Dorsum Excursion Index (DEI) for each consonant. This metric measures the relative use of the tongue dorsum, with more posterior consonants having higher values. We compared DEI values across groups and consonants using a linear mixed effects model. DEI was predicted by the interaction of consonant (baseline: /ʃ/) and speaker type (baseline: TD), including by-speaker random slopes for consonant and random intercepts for speaker. Results Overall DEI was not higher in children with CP+/-CL compared to typically developing children. Between groups the only significant difference was the position of /k/ relative to /ʃ/, where the difference between these two consonants was smaller in the children with CP+/-CL. Conclusions There was no support for the hypothesis that increased raising of the tongue dorsum is a common characteristic in children with repaired CP+/-CL. However, individual children may present with this pattern.

“…32 To analyse tongue shape and movement, the surface of the tongue must be tracked accurately. Ongoing work seeks to refine automatic tracking for both speech and swallowing assessment, 33 – 35 allowing the analyst to extract numerical values to measure movement. Another approach involves machine learning to classify images.…”

An initial framework for use of ultrasound by speech and language therapists in the UK: Scope of practice, education and governance

Background: There is growing evidence to support the use of ultrasound as a tool for the assessment and treatment of speech, voice and swallowing disorders across the Speech and Language Therapy profession. Research has shown that development of training competencies, engagement with employers and the professional body are vital to progressing ultrasound into practice. Methods: We present a framework to support translation of ultrasound into Speech and Language Therapy. The framework comprises three elements: (1) scope of practice, (2) education and competency and (3) governance. These elements align to provide a foundation for sustainable and high-quality ultrasound application across the profession. Results: Scope of practice includes the tissues to be imaged, the clinical and sonographic differentials and subsequent clinical decision-making. Defining this provides transformational clarity to Speech and Language Therapists, other imaging professionals and those designing care pathways. Education and competency are explicitly aligned with the scope of practice and include requisite training content and mechanisms for supervision/support from an appropriately trained individual in this area. Governance elements include legal, professional and insurance considerations. Quality assurance recommendations include data protection, storage of images, testing of ultrasound devices as well as continuous professional development and access to a second opinion. Conclusion: The framework provides an adaptable model for supporting expansion of ultrasound across a range of Speech and Language Therapy specialities. By taking an integrated approach, this multifaceted solution provides the foundation for those with speech, voice and swallowing disorders to benefit from advances in imaging-informed healthcare.

Purpose: This study investigates the hypothesis that younger speakers and speakers with more severe speech sound disorders are more likely to use simpler (undifferentiated) tongue gestures due to difficulties with, or immaturity of, lingual motor control. Method: The hypothesis is tested using cross-sectional secondary data analysis of synchronous audio and high-speed ultrasound recordings from children with idiopathic speech sound disorders ( n = 30, aged 5;0–12;11 [years;months]) and typically developing children ( n = 29, aged 5;8–12;10), producing /a/, /t/, /ɹ/, /l/, /s/, and /ʃ/ in an intervocalic /aCa/ environment. Tongue shape complexity is measured using NINFL (Number of INFLections) and modified curvature index (MCI) from splines fitted to ultrasound images at the point of maximal lingual gesture. Age, perceived accuracy, and consonant are used as predictors. Results: The results suggest that as age increases, children with speech sound disorders have lower MCI compared to typically developing children. Increase in age also led to decrease of MCI for the typically developing group. In the group of children with speech sound disorders, perceptually incorrect /ɹ/ productions have lower MCI than correct productions, relative to /a/. Conclusions: There is some evidence of systematic tongue shape complexity differences between typically developing children and children with speech sound disorders when accounting for increase in age. Among children with speech sound disorders, increase in age and perceptually incorrect consonant realizations are associated with decreasing tongue shape complexity.
