Case study using ultrasound to treat /r/.
BACKGROUND
Ultrasound has shown promise as visual feedback in remediation of /r/.


OBJECTIVE
To compare treatment for /r/ with and without ultrasound.


METHODS
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.


RESULTS
Formant values and trained listener ratings of speech samples indicated improvement in /r/ production, particularly after the introduction of ultrasound.


CONCLUSIONS
Ultrasound appeared to facilitate the acquisition of /r/ for the participant. Large-scale studies are needed to evaluate ultrasound further.
