The present study investigated the effect of fear on paralinguistic aspects of speech in patients suffering from panic disorder with agoraphobia (N = 25). An experiment was conducted that comprised two modules: Autobiographical Talking and Script Talking. Each module consisted of two emotional conditions: Fearful and Happy. Speech was recorded digitally and analyzed using PRAAT, a computer program designed to extract paralinguistic measures from digitally recorded spoken sound. In addition to subjective fear, several speech characteristics were measured as a reflection of psychophysiology: rate of speech, mean pitch and pitch variability. Results show that in Autobiographical Talking speech was slower, had a lower pitch, and a lower pitch variability than in Script Talking. Pitch variability was lower in Fearful than in Happy speech. The findings indicate that paralinguistic aspects of speech, especially pitch variability, are promising measures to gain information about fear processing during the recollection of autobiographical memories.
本研究调查了恐惧对患有广场恐怖症的惊恐障碍患者（N = 25）言语副语言方面的影响。进行了一项实验，该实验包括两个模块：自传式讲述和脚本讲述。每个模块都由两种情绪条件组成：恐惧和快乐。语音通过数字方式记录，并使用PRAAT进行分析，PRAAT是一个旨在从数字记录的语音中提取副语言测量指标的计算机程序。除了主观恐惧外，还测量了几个语音特征作为心理生理学的反映：语速、平均音高和音高变异性。结果表明，在自传式讲述中，语音比脚本讲述中更慢、音高更低、音高变异性更低。恐惧言语中的音高变异性低于快乐言语。研究结果表明，言语的副语言方面，尤其是音高变异性，是获取自传式记忆回忆过程中恐惧加工信息的有前景的测量指标。
