摘要

我们感兴趣的是调查在动态发音过程中情绪影响罗马尼亚元音共振峰相关水平的方式。在这项研究中,我们分析了语句/vine mama/(母亲来了),从中提取了每个元音的基本频率和共振峰,并研究了根据说话者表达的情绪(喜悦、悲伤、愤怒和情绪中立状态)计算的F0和F1-F4相关系数的变化。随后,我们应用简单线性回归来验证音高是否是估计低共振峰(F1和F2)的有效预测因子。我们获得的一些结果表明,对于/a1/和/a2/,无论情绪类型如何,决定系数(R2)的值都很低。对于元音/a1/,音高可以很好地预测愤怒和悲伤的形成峰F1,而对于F2,它只在愤怒和中性音调的情况下有效预测。另一方面,对于元音/a2/, F0可以很好地预测F1和F2,但只与愤怒有关。

A Correlational and Predictive Analysis of the Relationship between F0 and the Formants of Romanian Vowels
We are interested in investigating the manner in which emotions influence the level of correlation of the formants of Romanian vowels during dynamic pronunciation. In this study we analyzed the statement /vine mama/ (mother is coming) from which we extracted for each vowel the fundamental frequency and the formants, and we studied the variations of the correlation coefficients calculated for F0 and F1-F4 according to the emotion expressed by the speaker (joy, sadness, anger and the state of emotional neutrality). Subsequently, we applied simple linear regression to verify whether the pitch is an effective predictor for estimating the low formants (F1 and F2) or not. Some of the results we obtained indicate that for both /a1/ and /a2/ the values of the coefficient of determination (R2) were low regardless of the type of emotion. As for vowel /a1/, the pitch is a good predictor of formant F1 for anger and sadness, and for F2 it is an effective predictor only in the case of anger and neutral tone. On the other hand, for vowel /a2/, F0 is a good predictor for both F1 and F2, but only in association with anger.
