“…For example, mirrors are often used to help patients see their own lip or jaw movements. Using the acoustic signal, spectral feedback has also been used to teach participants with speech disorders to achieve proper formant structure for vowels or rhotics (McAllister Byun & Hitchcock, 2012;Shuster, Ruscello, & Smith, 1992;Shuster, Ruscello, & Toth, 1995).…”

Background: Individuals with acquired apraxia of speech (AOS) can lose precision of articulatory movements, including the ability to achieve correct production of specific sounds or sound sequences. Novel treatment approaches should be explored to enhance treatment outcomes. Aims: To evaluate the clinical feasibility of ultrasound visual feedback of the tongue for addressing errors on rhotics in a patient with AOS. Ultrasound visual feedback was used to provide knowledge of performance to the participant. Methods & Procedures:A multiple baseline single case report is presented to evaluate a treatment programme that uses visual feedback of the participant's tongue from realtime ultrasound images. A blocked practice schedule was implemented during 12 onehour therapy sessions; 30 minutes involved ultrasound visual feedback (10 minutes of pre-practice and 20 minutes of practice) and 20 minutes involved non-ultrasound practice. Cues were provided to modify tongue shape to achieve perceptually accurate production of rhotics, along with practice trials with increasing levels of phonetic complexity. The feedback type (verbal knowledge of performance and knowledge of results) and feedback frequency (number of trials with feedback) were structured to adhere to principles of motor learning. Outcomes & Results:The participant demonstrated moderate evidence of acquisition of prevocalic rhotics and strong evidence of acquisition of postvocalic rhotics during treatment. There was evidence of retention and generalisation only for postvocalic rhotics. An untreated context was probed regularly and showed no evidence of improvement. Conclusion:The results provide preliminary support for the feasibility of this treatment approach for improving speech accuracy in adults with acquired AOS. The improvements in stimulability for the treated sound sequences could be used to foster further motor learning.

“…It is not easy for children to comply with instructions regarding correct articulatory postures, especially in the case of /r/ and / 3^/ , sounds for which "there is little definitive tactile or kinesthetic feedback during production" (Shuster et al, 1995). A possiblc solution t o this problerrl is the use of the palatometer (such as the Model 6300 f' (~lr~lomrtrr.).…”

Shuster, Ruscello, and Toth (1995) demonstrated the use of the Real-Tzme Spectrogram to elicit correct /r/ from two children, ages 10 and 14 years, both of whom had failed to learn /r/ after extensive periods of traditional therapy. First, the children were taught to identify the formants on the video display when the clinician produced a variety of vowels.…”

Microcomputers can support phonological intervention in a variety of ways. Software and hardware can assist clinicians in identifying errors and establishing appropriate treatment targets. Technology can also help to determine the nature of errors so that optimal intervention methods are used. Specific technology tools for addressing phonological errors due to problems with articulation, phonemic identification, and phonetic mapping are discussed. The use of technology to document and analyze treatment performance is also addressed.

“…Rhotics are distinguished acoustically from other sonorants by the low height of the third formant (F3), which closely approximates the second formant (F2). Both case studies (Shuster, Ruscello, & Smith, 1992;Shuster, Ruscello, & Toth, 1995) and single-subject experimental studies (McAllister Byun, 2017;McAllister Byun & Campbell, 2016;McAllister Byun, Halpin, & Szeredi, 2015;McAllister Byun & Hitchcock, 2012) have reported that visual-acoustic biofeedback featuring a lowered F3 target can improve rhotic production in speakers who have not responded to other forms of intervention. One caution that has been raised in previous studies of various types of biofeedback (e.g., Gibbon & Paterson, 2006;McAllister Byun & Hitchcock, 2012;Preston et al, 2014) is that gains made in the treatment setting do not automatically generalize to contexts in which enhanced feedback is not available.…”

Purpose Recent research suggests that visual-acoustic biofeedback can be an effective treatment for residual speech errors, but adoption remains limited due to barriers including high cost and lack of familiarity with the technology. This case study reports results from the first participant to complete a course of visual-acoustic biofeedback using a not-for-profit iOS app, Speech Therapist's App for /r/ Treatment. Method App-based biofeedback treatment for rhotic misarticulation was provided in weekly 30-min sessions for 20 weeks. Within-treatment progress was documented using clinician perceptual ratings and acoustic measures. Generalization gains were assessed using acoustic measures of word probes elicited during baseline, treatment, and maintenance sessions. Results Both clinician ratings and acoustic measures indicated that the participant significantly improved her rhotic production accuracy in trials elicited during treatment sessions. However, these gains did not transfer to generalization probes. Conclusions This study provides a proof-of-concept demonstration that app-based biofeedback is a viable alternative to costlier dedicated systems. Generalization of gains to contexts without biofeedback remains a challenge that requires further study. App-delivered biofeedback could enable clinician–research partnerships that would strengthen the evidence base while providing enhanced treatment for children with residual rhotic errors.
