This case study reports results obtained from a young, profoundly deaf child, M, who was fitted with a single-channel vibrotactile device, the Tactaid I, at 29 months of age. Her progress in speech and language development was evaluated over a 14-month period. During this period, M learned to understand 101 words through lipreading and the Tactaid I, and to produce consistent approximations of 90 words. Her scores on language tests with hearing-impaired norms progressed from below average to above average for her age. M's scores on language tests with hearing norms also reflected significant progress, although she did not achieve normal language development. These results indicate that a single-channel vibrotactile aid may facilitate the acquisition of spoken language in a profoundly deaf child who is unable to benefit from a conventional hearing aid.
本案例研究报告了一名重度失聪幼儿M的相关结果。M在29个月大时佩戴了单通道触觉设备Tactaid I。在14个月的时间里对她的言语和语言发展进展进行了评估。在此期间，M通过唇读和Tactaid I学会了理解101个单词，并能连贯地说出近90个单词。按照针对听力受损者的标准进行语言测试时，她的分数从低于同龄人平均水平提升至高于平均水平。按照针对听力正常者的标准进行语言测试时，M的分数也显示出显著进步，尽管她并未实现正常的语言发展。这些结果表明，对于无法从传统助听器中获益的重度失聪儿童，单通道触觉辅助设备可能有助于其习得口语。
