构建心理辅导语音数据集，分析声调相似性与疗效关系
CUEMPATHY: A Counseling Speech Dataset for Psychotherapy Research
- 收集156场真实咨询对话，含39组治疗师-来访者配对
- 发现来访者评分与疗效相关，观察者评分则无关
- 治疗师与来访者声调强度相似度越高，疗效越好
心理治疗通常通过治疗师与来访者的口语交流进行。分析治疗互动中的语音特征有助于理解有效治疗的影响因素。本文介绍CUEMPATHY，一个从实际咨询会话中收集的大规模语音数据集，包含156次咨询会话和39组治疗师-来访者配对。详细描述了语音数据采集、主观评分（一名观察者和两名来访者评分）及转录过程。开发了自动语音与文本处理系统，用于定位每场会话中说话人轮换的时间戳。考察三种主观评分之间的关系发现，观察者与来访者评分无显著相关性，而来访者评分之间存在显著相关性。治疗师与来访者在语音强度上的相似性（以说话人轮次级强度绝对差值的平均值衡量）与心理治疗结果相关。本文还介绍了近期基于CUEMPATHY的声学与语言特征研究。
原文摘要 · Abstract (English)
Psychotherapy or counseling is typically conducted through spoken conversation between a therapist and a client. Analyzing the speech characteristics of psychotherapeutic interactions can help understand the factors associated with effective psychotherapy. This paper introduces CUEMPATHY, a large-scale speech dataset collected from actual counseling sessions. The dataset consists of 156 counseling sessions involving 39 therapist-client dyads. The process of speech data collection, subjective ratings (one observer and two client ratings), and transcription are described. An automatic speech and text processing system is developed to locate the time stamps of speaker turns in each session. Examining the relationships among the three subjective ratings suggests that observer and client ratings have no significant correlation, while the client-rated measures are significantly correlated. The intensity similarity between the therapist and the client, measured by the averaged absolute difference of speaker-turn-level intensities, is associated with the psychotherapy outcomes. Recent studies on the acoustic and linguistic characteristics of the CUEMPATHY are introduced.
