Anecdotally, velar fronting can be difficult to remediate in some children. This pilot study examined the use of ultrasound visual feedback in remediating velar fronting in typically developing children. A single-case, multiple-baseline across-subjects experimental design was used to examine acquisition, retention and generalisation of velar treatment targets. Two otherwise typically developing children (P1, aged 4;0; P3, aged 4;11) completed the study. The productions of /k/ and /ɡ/ at syllable level were targeted during treatment. P1 improved her productions of /k/ and /ɡ/ at syllable level during the treatment period and achieved correct production at word level during follow-up. P3 made no improvements in his productions of velar targets. This study suggests that ultrasound visual feedback may be an option for remediating velar fronting in some preschoolers. Further study is required.
据传闻，软腭前移在一些儿童中可能难以矫正。这项初步研究考察了超声视觉反馈在矫正发育正常儿童软腭前移中的应用。采用单病例、跨受试者多基线实验设计来考察软腭治疗目标的习得、保持和泛化情况。两名发育正常的儿童（P1，4岁0个月；P3，4岁11个月）完成了该研究。治疗期间以音节水平的/k/和/ɡ/发音为目标。P1在治疗期间提高了她在音节水平的/k/和/ɡ/发音，并在随访期间在单词水平上实现了正确发音。P3在软腭目标发音上没有改善。这项研究表明，超声视觉反馈可能是矫正一些学龄前儿童软腭前移的一种选择。还需要进一步研究。
