Abstract Children with hearing loss frequently have diffi culty learning North American English /r/. The purpose of the present study was to investigate the remediation of North American English /r/ by establishing its tongue movement components for three adolescents with recent cochlear implants (CIs) through the use of ultrasound as an adjunct to speech therapy. The three adolescents had all been diagnosed with severe-to-profound bilateral sensorineural hearing loss, and had recently received unilateral CIs. All three students wore a hearing aid in their other ear. Ultrasound was used to assist in establishing the gestural components of /r/ as a starting point for accurate /r/ production: tongue root retraction, retrofl exion or bunching and midline grooving. A single subject design was used, with analyses of the gestural components of /r/ before, during and after intervention. All participants were able to learn the gestural components of /r/ with ultrasound. Furthermore, one of the participants gained accurate production of /r/ in isolation and at the word level.

Les enfants ayant une perte auditive ont souvent de la diffi culté à apprendre le son /r/ de l’anglais nord-américain. La présente étude visait à examiner la correction de la production du /r/ de l’anglais nord-américain en établissant les mouvements linguaux nécessaires à sa production à l’aide d’ultrasons en plus de la thérapie orthophonique chez trois adolescents ayant un implant cochléaire. Les trois adolescents avaient eu un diagnostic d’une surdité neurosensorielle bilatérale sévère à profonde et avaient récemment reçu un implant cochléaire unilatéral. Les trois portaient un appareil auditif à l’autre oreille. Les ultrasons ont servi à établir les composantes gestuelles du /r/ comme point de départ pour la production adéquate de ce son : la rétraction, la rétrofl exion ou l’épaississement de la base de la langue et la formation d’un creux médian. L’étude utilise une méthode à sujet unique où l’analyse des composantes gestuelles du /r/ a été effectuée avant, pendant et après l’intervention. Tous les participants ont pu apprendre les composantes gestuelles du /r/ à l’aide des ultrasons. De plus, un des participants a acquis une production précise du /r/ en isolation et dans un mot.
