Research on tactual perception of speech has shown that many phonetic contrasts can be transmitted to the deaf through artificial hearing devices that stimulate the sense of touch. Past research has emphasized long-term training with tactual reception for the achievement of maximal perceptual performance. The present study demonstrates that, with a brief training period, deaf adolescents can attain a high level of perceptual performance with a tactual speech system in discrimination of certain hard-to-lipread word pairs pronounced by both a male and female speaker. Thus some speech sounds previously indistinguishable by the deaf people can be immediately available for speech comprehension through the tactual vocoder; and other speech sounds will be recognized with further training. The reason that some contrasts are learned quickly and others require extensive training may be found in a pattern perception postulate proposed by Gavin (1979): word patterns that result in stimulation across a greater area of skin tend to be more discriminable than word patterns which stimulate only small areas of the skin.
对语音触觉感知的研究表明，许多语音对比可以通过刺激触觉的人工听力设备传递给聋人。过去的研究强调通过触觉接收进行长期训练，以实现最大的感知性能。本研究表明，经过短暂的训练期，聋青少年在辨别男性和女性说出的某些难以唇读的单词对时，能够通过触觉语音系统达到较高的感知性能水平。因此，聋人以前无法区分的一些语音可以通过触觉声码器立即用于语音理解；而其他语音经过进一步训练后也将被识别。一些对比能快速学会而其他对比需要大量训练的原因，可能可以在加文（1979年）提出的模式感知假设中找到：导致皮肤更大区域受到刺激的单词模式往往比只刺激皮肤小区域的单词模式更具可辨别性。
