“…The production of a sound demands subtlety of articulation and specific motor and sensorial abilities (5,28) that requires the child's maturation in both cognitive and motor terms (18) . Growth causes slow and significant changes on shape and size of the articulators which causes constant adaptation from motor control (27) .…”

OBJETIVO: Analisar a efetividade da estimulabilidade como prova complementar ao diagnóstico do transtorno fonológico (TF) e descrever o desempenho de crianças com ausência de sons no inventário fonético quanto a sons ausentes estimuláveis, gravidade, gênero, idade e ocorrência de diferentes processos fonológicos. MÉTODOS: Participaram 130 crianças de ambos os gêneros, entre 5 anos e 10 anos e 10 meses de idade, distribuídas em dois grupos: Grupo Pesquisa (GP), composto por 55 crianças com TF; e Grupo Controle (GC), composto por 75 crianças sem alterações fonoaudiológicas. A partir da aplicação da prova de Fonologia, foi calculada a gravidade do TF por meio do Percentual de Consoantes Corretas-Revisada (PCC-R) e verificado o inventário fonético. Para cada som ausente do inventário foi aplicada a estimulabilidade em imitação de palavras. O GP foi dividido em GP1 (27 crianças que apresentaram sons ausentes) e GP2 (28 crianças com inventário completo). RESULTADOS: Nenhuma criança do GC apresentou som ausente no inventário e no GP1 49% apresentaram sons ausentes. Houve ausência da maioria dos sons da língua. As médias do PCC-R foram menores no GP1, indicando maior gravidade. No GP1, 22 crianças foram estimuláveis e cinco não o foram a qualquer som. Houve associação entre os processos fonológicos mais ocorrentes no TF e a necessidade de avaliação da estimulabilidade, o que indica que a dificuldade em produzir os sons ausentes reflete dificuldade de representação fonológica. A estimulabilidade sofre influência da idade, mas não do gênero. CONCLUSÃO: A prova de estimulabilidade é efetiva para identificar dentre crianças com sons ausentes do inventário, aquelas que são estimuláveis. Tais crianças com TF, que apresentam sons ausentes do inventário, são mais graves uma vez que os valores do PCC-R são mais baixos. As crianças com sons ausentes são estimuláveis em sua maioria, e podem não ser estimuláveis para sons com estrutura silábica ou gesto articulatório complexos. A dificuldade em produzir os sons ausentes reflete dificuldade de representação fonológica. A produção motora da fala demonstrou receber influência da maturação de forma semelhante entre meninos e meninas.

Diagnostic ultrasound imaging has been a common tool in medical practice for several decades. It provides a safe and effective method for imaging structures internal to the body. There has been a recent increase in the use of ultrasound technology to visualize the shape and movements of the tongue during speech, both in typical speakers and in clinical populations. Ultrasound imaging of speech has greatly expanded our understanding of how sounds articulated with the tongue (lingual sounds) are produced. Such information can be particularly valuable for speech-language pathologists. Among other advantages, ultrasound images can be used during speech therapy to provide (1) illustrative models of typical (i.e. "correct") tongue configurations for speech sounds, and (2) a source of insight into the articulatory nature of deviant productions. The images can also be used as an additional source of feedback for clinical populations learning to distinguish their better productions from their incorrect productions, en route to establishing more effective articulatory habits.Ultrasound feedback is increasingly used by scientists and clinicians as both the expertise of the users increases and as the expense of the equipment declines. In this tutorial, procedures are presented for collecting ultrasound images of the tongue in a clinical context. We illustrate these procedures in an extended example featuring one common error sound, American English /r/. Images of correct and distorted /r/ are used to demonstrate (1) how to interpret ultrasound images, (2) how to assess tongue shape during production of speech sounds, (3), how to categorize tongue shape errors, and (4), how to provide visual feedback to elicit a more appropriate and functional tongue shape. We present a sample protocol for using real-time ultrasound images of the tongue for visual feedback to remediate speech sound errors. Additionally, example data are shown to illustrate outcomes with the procedure.

“…Various technologies, such as ultrasound and electropalatography, have been used to provide real-time information about the location and movements of the articulators during speech (e.g., Adler-Bock, Bernhardt, Gick, & Bacsfalvi, 2007;Gibbon, Stewart, Hardcastle, & Crampin, 1999;McAllister Byun, Hitchcock, & Swartz, 2014;Preston et al, 2013Preston et al, , 2014. Another alternative is visual-acoustic biofeedback, such as a dynamic visual display of the formants or resonant frequencies of the vocal tract.…”

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.

The Use of Ultrasound in Remediation of North American English /r/ in 2 Adolescents

Abstract: Two-dimensional dynamic ultrasound appears to have potential utility for remediation of /r/ in speakers with residual /r/ impairment. Further research is needed with larger numbers of participants to establish the relative efficacy of ultrasound in treatment.
