目的本研究旨在探讨儿童、青年和老年人在安静和噪音环境中产生的会话和清晰语音句子的可懂度。相对说话者的可理解性进行了评估，在不同的说话风格。方法61名青年受试者在-5 dB信噪比条件下听混合语音噪声的句子。这些分析检查了在会话、清晰和噪音适应条件下以及三个谈话者组的正确分数。相关分析研究说话者的可理解性是否在说话风格适应中是一致的。结果噪声适应和清晰的语音显着提高可懂度为年轻的成年听众。三个谈话者组的可理解性改善各不相同。值得注意的是，可理解性的好处是最小的儿童的说话风格的修改。听众还认为，与年轻的谈话者相比，老年人在噪音中产生的讲话不太容易理解。谈话者的可懂度之间的会话和清晰的语音在安静的强烈相关，但不是在安静和噪音中产生的会话语音。结论研究结果提供的证据表明，与年龄和沟通障碍相关的可懂度变化有可能帮助临床决策的个人与语言障碍，特别是构音障碍。
Purpose This study examined intelligibility of conversational and clear speech sentences produced in quiet and in noise by children, young adults, and older adults. Relative talker intelligibility was assessed across speaking styles. Method Sixty-one young adult participants listened to sentences mixed with speech-shaped noise at -5 dB signal-to-noise ratio. The analyses examined percent correct scores across conversational, clear, and noise-adapted conditions and the three talker groups. Correlation analyses examined whether talker intelligibility is consistent across speaking style adaptations. Results Noise-adapted and clear speech significantly enhanced intelligibility for young adult listeners. The intelligibility improvement varied across the three talker groups. Notably, intelligibility benefit was smallest for children's speaking style modifications. Listeners also perceived speech produced in noise by older adults to be less intelligible compared to the younger talkers. Talker intelligibility was correlated strongly between conversational and clear speech in quiet, but not for conversational speech produced in quiet and in noise. Conclusions Results provide evidence that intelligibility variation related to age and communicative barrier has the potential to aid clinical decision making for individuals with speech disorders, particularly dysarthria.
