进行了两个实验，以探讨一个单一的振动触觉刺激器传达语调（问题与声明）和对比应力（四个4或5字的句子的前三个字之一）的有效性。在实验一中，人工听觉正常的受试者判断压力和语调在平衡的视觉单独和视觉触觉条件。六个声音的基本频率触觉的转换进行了测试。两个句子类型都是全浊的，两个句子包含清音辅音。朗读的好处是显著的，但很小。未观察到转化之间的差异。在实验II中，仅呈现触觉刺激。转换之间出现了显着的差异，语调比重音判断的差异更大。令人惊讶的是，在几个转换中，单独的语音语调识别比视觉触觉识别更准确。
Two experiments were conducted to explore the effectiveness of a single vibrotactile stimulator to convey intonation (question versus statement) and contrastive stress (on one of the first three words of four 4- or 5-word sentences). In experiment I, artificially deafened normal-hearing subjects judged stress and intonation in counterbalanced visual-alone and visual-tactile conditions. Six voice fundamental frequency-to-tactile transformations were tested. Two sentence types were voiced throughout, and two-contained unvoiced consonants. Benefits to speechreading were significant, but small. No differences among transformations were observed. In experiment II, only the tactile stimuli were presented. Significant differences emerged among the transformations, with larger differences for intonation than for stress judgements. Surprisingly, tactile-alone intonation identification was more accurate than visual-tactile for several transformations.
