The aim of this study was to determine the influence of emotional expression in spectral energy distribution in professional theater actors.
The study design is a quasi-experimental study.
Thirty-seven actors, native Spanish speakers, were included. All subjects had at least 3 years of professional experience as a theater actor and no history of vocal pathology for the last 5 years. Participants were recorded during a read-aloud task of a 230-word passage, expressing six different emotions (happiness, sadness, fear, anger, tenderness, and eroticism) and without emotion (neutral state). Acoustical analysis with long-term average spectrum included three variables: the energy level difference between the F(1) and fundamental frequency (F(0)) regions, ratio between 1-5kHz and 5-8kHz, and alpha ratio.
All the different emotions differ significantly from the neutral state for alpha ratio and 1-5/5-8kHz ratio. Only significant differences between "joy," "anger," and "eroticism" were found for L1-L0 ratio. Statistically significant differences between genders for the three acoustical variables were also found.
The expression of emotion impacts the spectral energy distribution. On the one hand emotional states characterized by a breathy voice quality such as tenderness, sadness, and eroticism present a low harmonic energy above 1kHz, high glottal noise energy, and more energy on F(0) than overtones. On the other hand, emotional states such as joy, anger, and fear are characterized by high harmonic energy greater than 1kHz (less steep spectral slope declination), low glottal noise energy, and more energy on the F(1) than F(0) region.
本研究旨在确定情感表达对专业戏剧演员声谱能量分布的影响。
研究设计为准实验研究。
纳入 37 名母语为西班牙语的演员。所有受试者均具有至少 3 年的专业戏剧演员经验，且在过去 5 年内无嗓音病理学病史。参与者在朗读一段 230 词的文章时被记录，表达六种不同的情绪（高兴、悲伤、恐惧、愤怒、温柔和色情）和无情绪（中性状态）。声学分析包括三个变量：F(1)和基频（F(0)）区域之间的能量水平差、1-5kHz 和 5-8kHz 之间的比率以及α比率。
所有不同的情绪在α比率和 1-5/5-8kHz 比率方面与中性状态有显著差异。仅在 L1-L0 比率方面发现“高兴”、“愤怒”和“色情”之间存在显著差异。还发现了三种声学变量在性别之间存在统计学上的显著差异。
情感表达会影响声谱能量分布。一方面，像温柔、悲伤和色情这样的声音质量带气息的情感状态，在 1kHz 以上具有较低的谐波能量、较高的声门噪声能量以及更多的 F(0)能量而非泛音能量。另一方面，像高兴、愤怒和恐惧这样的情感状态的特点是 1kHz 以上具有较高的谐波能量（谱斜率下降较平缓）、较低的声门噪声能量以及更多的 F(1)能量而非 F(0)区域能量。
