Emotional states can be conveyed by vocal cues such as pitch and intensity. Despite the ubiquity of cellular telephones, there is limited information on how vocal emotional states are perceived during cell-phone transmissions. Emotional utterances (neutral, happy, angry) were elicited from two female talkers and simultaneously recorded via microphone and cell-phone. Ten-step continua (neutral to happy, neutral to angry) were generated using the straight algorithm. Analyses compared reaction time (RT) and emotion judgment as a function of recording type (microphone vs cell-phone). Logistic regression revealed no judgment differences between recording types, though there were interactions with emotion type. Multi-level model analyses indicated that RT data were best fit by a quadratic model, with slower RT at the middle of each continuum, suggesting greater ambiguity, and slower RT for cell-phone stimuli across blocks. While preliminary, results suggest that critical acoustic cues to emotion are largely retained in cell-phone transmissions, though with effects of recording source on RT, and support the methodological utility of collecting speech samples by phone.
情绪状态可以通过音高和强度等声音线索来传达。尽管手机无处不在，但关于在手机通话过程中如何感知声音中的情绪状态的信息却很有限。从两名女性谈话者那里获取了情绪话语（中性、高兴、愤怒），并同时通过麦克风和手机进行记录。使用直线算法生成了十步连续体（从中性到高兴、从中性到愤怒）。分析比较了反应时间（RT）和作为记录类型（麦克风与手机）函数的情绪判断。逻辑回归显示记录类型之间没有判断差异，不过存在与情绪类型的交互作用。多层次模型分析表明，RT数据最适合二次模型，在每个连续体的中间反应时间较慢，这表明存在更大的模糊性，并且在各个组块中手机刺激的反应时间较慢。虽然是初步的，但结果表明情绪的关键声学线索在手机通话中基本得以保留，不过记录源对反应时间有影响，并且支持通过手机收集语音样本的方法学效用。
