目的：本研究调查了9-14奥尔兹自发言语的声学特征，以及当对话者的可懂度被人为降低时，他们适应这些特征以保持有效交流的能力。方法：记录了96名儿童（50 F，46 M）从事解决问题的任务与同性朋友;录音为20名成年人作为参考。该任务是在良好的听力条件（正常传输- NORM）和降级传输条件（DEG）下进行的。分析发音率、基频中值（f0）、f0范围和1-3 kHz范围内的相对能量。结果如下：随着年龄的增长，儿童显著降低了他们的中值f0和f0范围，成为更快的说话者，并降低了他们在自发言语中的中频能量。儿童产生类似的清晰的语音适应（在DEG）的成年人，但只有11-14岁的儿童增加f0范围，一个无益的策略，不通过声码器传输。儿童所做的改变与发声努力的普遍增加是一致的。结论：言语产生的进一步发展发生在童年后期。儿童使用清晰的言语策略来帮助面临可理解性问题的对话者，但可能无法将这些策略调整到与成人相同的程度。
Purpose: This study investigated the acoustic characteristics of spontaneous speech by 9-14 year olds, and their ability to adapt these characteristics to maintain effective communication when intelligibility was artificially degraded for their interlocutor. Methods: Recordings were made for 96 children (50 F, 46 M) engaged in a problem-solving task with a same-sex friend; recordings for 20 adults were used as reference. The task was carried out in good listening conditions (normal transmission - NORM) and in a degraded transmission condition (DEG). Articulation rate, median fundamental frequency (f0), f0 range and relative energy in 1-3 kHz range were analyzed. Results: With increasing age, children significantly reduced their median f0 and f0 range, became faster talkers and reduced their mid-frequency energy in spontaneous speech. Children produced similar clear speech adaptations (in DEG) as adults but only children aged 11-14 increased f0 range, an unhelpful strategy as not transmitted via the vocoder. Changes made by children were consistent with a general increase in vocal effort. Conclusion: Further developments in speech production take place during later childhood. Children use clear speech strategies to benefit an interlocutor facing intelligibility problems but may not be able to attune these strategies to the same degree as adults.
