PurposeWe评估的效果的语音补充策略，以减少率和提高可理解性脑瘫children with cerebralpals.MethodTwenty-five脑瘫儿童（法师= 12.08年）完成了结构化的讲话任务，在2个语音条件：习惯性语音和缓慢的语音。15名儿童有轻度的可懂度缺陷，10名有中度至重度的可懂度缺陷。在每种情况下，孩子们重复2-7个单词的话语。在习惯性言语条件下，儿童使用自然的、不变的语速。在慢速言语条件下，孩子们被提示在单词之间插入停顿。可懂度评级获得了不熟悉的成年听众（n= 100）的正字法transmittance。言语速率，每分钟的话，测量每个话语。ResultsAll儿童，无论严重程度组，能够降低他们的讲话速度时，实施缓慢的语音策略。只有中重度组的儿童在实施慢速言语策略时清晰度有所提高。虽然有相当大的个体差异，有一个更大的改善，在可理解性较长的话语相比，较短的thes.ConclusionA缓慢的语音策略可能是有益的中度严重的可理解性赤字的儿童谁在较长的话语。未来的研究应寻求进一步研究的临床可行性，缓慢的语言与儿童的可懂度降低。
PurposeWe evaluated the effects of a speech supplementation strategy to reduce rate and improve intelligibility in children with cerebral palsy.MethodTwenty-five children with cerebral palsy (Mage= 12.08 years) completed a structured speaking task in 2 speech conditions: habitual speech and slow speech. Fifteen children had mild intelligibility deficits; 10 had moderate–severe intelligibility deficits. In each condition, children repeated utterances of 2–7 words in length. In the habitual speech condition, children used their natural and unaltered speaking rate. In the slow speech condition, children were cued to insert pauses between words. Intelligibility ratings were obtained from orthographic transcriptions by unfamiliar adult listeners (n= 100). Speech rate, in words per minute, was measured for each utterance.ResultsAll children, regardless of severity group, were able to reduce their rate of speech when implementing the slow speech strategy. Only children in the moderate–severe group showed an improvement in intelligibility when implementing the slow speech strategy. Although there was considerable individual variability, there was a greater improvement in intelligibility for longer utterances compared to shorter ones.ConclusionA slow speech strategy may be beneficial for children with moderate–severe intelligibility deficits who speak in longer utterances. Future studies should seek to further examine the clinical feasibility of slow speech for children with reduced intelligibility.
