Abstract

This study examines the ability to express distinct emotions of negative and positive valences through voice modulations (i.e., affective prosody production) and how the speaker’s gender and age influence this ability. A sample of 31 neurologically healthy adults (17 women and 14 men, aged 41–76) were asked to say “papa” with six emotional tones—sadness, anger, fear, pleasant surprise, joy, and awe—in response to affect-evoking scenarios. The speakers’ vocal expressions were recorded and then assessed by five expert raters and 30 naive listeners using an emotion recognition task. Results showed that negative emotions were expressed more accurately than positive ones, highlighting a valence effect. In addition, female speakers showed higher recognition rates for their expressions of vocal emotions than male speakers. Furthermore, aging was associated with a moderate decline in the accuracy of prosodic emotional expression. Despite generally lower recognition rates from naive listeners compared to expert raters, recognition rates for all emotions, with the exception of awe, were not statistically different between listener groups. In conclusion, cognitively healthy adults can convey discrete emotions through prosody, including distinct positive emotions, but there are significant differences depending on the emotion expressed and individual speaker characteristics. These results highlight the complexity of affective prosody production and contribute to the understanding of individual differences in nonverbal emotional expression.

认知健康的成年演讲者的声乐情感表达:情感类别、性别和年龄的影响
本研究探讨了通过声音调制(即情感拟声)表达消极和积极情绪的能力,以及说话者的性别和年龄对这种能力的影响。研究人员要求 31 名神经系统健康的成年人(17 名女性和 14 名男性,年龄在 41-76 岁之间)在说 "爸爸 "时用六种情绪语调--悲伤、愤怒、恐惧、惊喜、喜悦和敬畏--来回应情感激发情景。说话者的声音表达被录制下来,然后由五位专家评分员和 30 位天真的听众通过情绪识别任务进行评估。结果显示,消极情绪的表达比积极情绪的表达更准确,这凸显了情绪效应。此外,女性说话者的声音情绪表达识别率高于男性说话者。此外,衰老与前声情绪表达准确性的适度下降有关。尽管与专家评分者相比,幼稚听众的识别率普遍较低,但除了敬畏之外,其他情绪的识别率在听者群体之间并无统计学差异。总之,认知健康的成年人可以通过拟声来传达不同的情绪,包括明显的积极情绪,但根据所表达的情绪和说话者的个体特征,两者之间存在显著差异。这些结果凸显了情感拟声词产生的复杂性,有助于人们理解非语言情感表达的个体差异。
