论文摘要
在基于对话的心理治疗中，治疗师使用言语技术来帮助客户表达思想和感觉并改变行为。特别是，治疗师如何传达同理心是心理治疗课程的基本质量指数，并且与心理治疗结果有关。在本文中，我们分析了治疗师言语的韵律，并试图将治疗师的口语风格与主观上的同理心相关联。开发了一个自动语音和文本处理系统，以将心理治疗会话的长期记录分为带有文本抄录的暂停限制的话语。数据驱动的聚类应用于多个课程中不同治疗师的话语。对于每个群集，根据量化的韵律特征参数得出话语类型的类型学表示。可以从与同理心相关的显着话语流派中观察和解释治疗师的突出风格。使用显着的话语类型，将心理治疗会话分为``高''和``'低点''的同理心水平的精度是$ 71 \％$。结果的分析表明，如果治疗师慢慢说话或迅速说话的话，同理心往往往往是（1）较低； （2）如果治疗师以稳定的语气和音量与客户交谈。
In conversation-based psychotherapy, therapists use verbal techniques to help clients express thoughts and feelings, and change behavior. In particular, how well therapists convey empathy is an essential quality index of psychotherapy sessions and is associated with psychotherapy outcome. In this paper, we analyze the prosody of therapist speech and attempt to associate the therapist's speaking style with subjectively perceived empathy. An automatic speech and text processing system is developed to segment long recordings of psychotherapy sessions into pause-delimited utterances with text transcriptions. Data-driven clustering is applied to the utterances from different therapists in multiple sessions. For each cluster, a typological representation of utterance genre is derived based on quantized prosodic feature parameters. Prominent speaking styles of the therapist can be observed and interpreted from salient utterance genres that are correlated with empathy. Using the salient utterance genres, an accuracy of $71\%$ is achieved in classifying psychotherapy sessions into ``high" and ``low" empathy level. Analysis of results suggests that empathy level tends to be (1) low if therapists speak long utterances slowly or speak short utterances quickly; and (2) high if therapists talk to clients with a steady tone and volume.
