在这篇文章中，我们评估了四名身体健全的参与者使用前臂背侧呈现的触觉线索来区分发音辅音位置的能力。此外，我们通过两项心理物理研究，确定了10名参与者穿着触觉袖子的前臂背侧皮肤的处理能力。我们的第一个研究表明，当振动的位置不同时，人类用户可以可靠地识别沿前臂长度排列的2-3个手爪。我们的第二项研究表明，局域振动的物理位置与感知到的物理排列成线性映射。基于这些发现，随后的语音实验使用了六个等距离放置的手爪，并将口腔内收缩的位置映射为前臂上的方向提示。语音研究的结果表明，参与者能够指出两个随机呈现的触觉提示(源自辅音-元音-辅音(CVC)无意义音节)中，哪一个的前辅音更接近嘴唇。当辅音在嘴里产生的距离较远时，以及(Iii)发音特征的位置和方式都不同时，(I)摩擦音比塞音的辨别性能更好。这项研究还表明，前臂使用线索的辨别性能低于之前研究中使用指垫的辨别性能。
In this paper, we evaluate the ability of four able-bodied participants to discriminate the articulation location for spoken consonants, using tactile cues presented on the dorsal side of their forearm. Additionally, we determine the processing capability of the dorsal forearm's skin with a tactile sleeve worn by ten participants using two psychophysical studies. Our first study shows that 2–3 tactors arranged along the length of the forearm can be reliably identified by human users, when only the location of vibration is varied. Our second study indicates that the physical placement of localized vibrations map linearly to the perceived physical arrangement. Based on these findings, the subsequent speech experiment uses six tactors placed equidistant from each other and maps location of the constriction inside the mouth as directional cues on the forearm. Results of the speech study show that participants are able to indicate which of two randomly presented tactile cues (derived from consonant-vowel-consonant (CVC) non-sense syllables) has the preceding consonant closer to the lips. The discrimination performance is better (i) with fricatives than plosives, (ii) when the consonants are produced further apart inside the mouth, and (iii) when both place and manner of articulation feature is varied. The study also shows that discrimination performance with cues applied to the forearm is inferior to that with the fingerpads utilized in a previous study.
