在本文中的结果提出了一个听觉描述的32个nonmanipulated，低通滤波，和随机拼接的语音样本。描述由三名评分员在24个言语量表上的评分组成。本研究的目的是建立对言语知觉的操作的影响。深入了解这个问题是通过检查的可靠性，和之间的相关性，在三个条件下的评级，并考虑了一些t检验的结果。看来，过滤后，除了韵律特征，一些语音质量特征仍然存在于信号中，发音信息被删除。拼接后，不仅语音质量特征，但也有一些发音和韵律信息仍然存在。此外，研究表明，这两种内容掩蔽技术都会带来感知上的系统性偏差。这些发现与低通滤波和随机拼接用作掩蔽技术的情感和个性研究有关。
In this paper the results are presented of an auditory description of 32 nonmanipulated, low-pass-filtered, and random-spliced speech samples. The description consisted of the ratings by three raters on 24 speech scales. The aim of this study was to establish the effects of the manipulations on the perception of speech. Insight into this question was gained by examining the reliability of, and the correlations between, the ratings in the three conditions, and by considering the outcomes of a number of t tests. It appeared that, after filtering, in addition to prosodic features, a number of voice quality characteristics remain present in the signal; articulatory information is eliminated. After splicing, not only voice quality features but also some articulatory and prosodic information remain present. Moreover, the study revealed that both content-masking techniques bring about systematic biases in the perception. These findings are relevant to emotion and personality research in which low-pass filtering and random splicing are used as masking techniques.
