越来越多的实验研究表明，言语补充策略可以显著提高构音障碍患者的言语清晰度（D。Beukelman & K. Yorkston，1977; E. Crow & P. Enderby，1989; L.亨特，T。Pring，& S. Martin，1991; K. C. Hustad & D. R. Beukelman，2001）。然而，言语补充策略实际上是由构音障碍的发言者实施的研究是有限的，使其临床疗效未知。本研究比较了清晰度和语音速率的差异扬声器实施3种策略（主题，字母表，并结合主题和字母表补充）和习惯性（noncue）语音控制条件下5扬声器严重构音障碍。结果显示，结合线索和字母线索产生显着更高的可懂度分数和较慢的语音速率比主题线索和非线索的讲话。总体而言，主题线索和非线索语音没有不同的可懂度或语音速率。结合线索和字母线索没有彼此不同的可懂度，但是，语音速率之间的2个策略显着不同。发言者之间的个体差异一般与组的调查结果一致。结果有些不同，从以前的研究中，策略实验叠加在习惯性的语音信号。然而，研究结果提供的证据表明，字母线索和组合线索可以有一个重要的影响，对严重构音障碍的扬声器的可懂度。
A growing body of experimental research suggests that speech supplementation strategies can markedly increase speech intelligibility for individuals with dysarthria (D. Beukelman & K. Yorkston, 1977; E. Crow & P. Enderby, 1989; L. Hunter, T. Pring, & S. Martin, 1991; K. C. Hustad & D. R. Beukelman, 2001). However, studies in which speech supplementation strategies were actually implemented by speakers with dysarthria are limited, leaving their clinical efficacy unknown. The present study compared intelligibility and speech rate differences following speaker implementation of 3 strategies (topic, alphabet, and combined topic and alphabet supplementation) and a habitual (noncued) speech control condition for 5 speakers with severe dysarthria. Results revealed that combined cues and alphabet cues yielded significantly higher intelligibility scores and slower speech rates than topic cues and noncued speech. Overall, topic cues and noncued speech did not differ from one another with regard to intelligibility or speech rate. Combined cues and alphabet cues did not differ from one another with regard to intelligibility; however, speech rate was significantly different between the 2 strategies. Individual differences among speakers were generally consistent with group findings. Results were somewhat different from previous research in which strategies were experimentally superimposed on the habitual speech signal. However, findings provide evidence that alphabet cues and combined cues can have an important effect on intelligibility for speakers with severe dysarthria.
