Abstract
Background: Ultrasound has shown promise as visual feedback in remediation of /ɹ/.
Aims: To compare treatment for /ɹ/ with and without ultrasound.
Methods & Procedures: A Canadian English‐speaking adolescent participated in a case study with a no treatment baseline, alternating treatment blocks with and without ultrasound and a final no treatment period.
Outcomes & Results: Formant values and trained listener ratings of speech samples indicated improvement in /ɹ/ production, particularly after the introduction of ultrasound.
Conclusions: Ultrasound appeared to facilitate the acquisition of /ɹ/ for the participant. Large‐scale studies are needed to evaluate ultrasound further.
Notes
1. Caveat regarding the phrase ‘say X ten times’: the [t] of ten would be co‐articulated with an actual preceding WF [ɹ], sometimes making segmentation more challenging for acoustic analysis.
