Use of wearable tactile speech perception devices is suggested to help overcome the difficulties in speech production resulting from severe and profound hearing impairment in children. This suggestion is based on the assumption that subjects can use tactile input in isolation, or in combination with information from residual aided hearing, to monitor and modify their speech. The present study evaluated the benefits to articulation provided through use of a multichannel electrotactile device ("Tickle Talker").
Six profoundly hearing-impaired children were videotaped speaking with the Tickle Talker on and with the Tickle Talker off during conversations with their audiologist. Five of the subjects also wore their binaural hearing aids during all recorded conversations. The number of vowels, consonants, and overall phonemes correctly articulated by each child in the two conditions were compared.
One subject improved articulation of initial consonants and initial phonemes; one subject improved articulation of total vowels, total consonants, initial consonants, total phonemes, and initial phonemes; and a third subject improved articulation of total vowels and medial phonemes.
Use of on-line tactile feedback from the Tickle Talker may benefit the articulation accuracy of some children, and the device may therefore be suitable to use with children who have not responded to more traditional speech training techniques.
有人建议使用可穿戴式触觉语音感知设备，以帮助克服儿童严重和极重度听力损失导致的言语产生困难。这一建议基于这样的假设，即受试者可以单独使用触觉输入，或与残余助听信息相结合，来监测和调整自己的言语。本研究评估了使用多通道电触觉设备（“挠痒痒交谈器”）对发音的益处。
六名极重度听力损失儿童在与听力学家交谈时，分别在佩戴和不佩戴“挠痒痒交谈器”的情况下被录像。五名受试者在所有录制的对话中也佩戴了双耳助听器。比较了每个孩子在两种情况下正确发出的元音、辅音和总音素的数量。
一名受试者改善了首辅音和首音素的发音；一名受试者改善了总元音、总辅音、首辅音、总音素和首音素的发音；第三名受试者改善了总元音和中间音素的发音。
使用“挠痒痒交谈器”的在线触觉反馈可能对一些儿童的发音准确性有益，因此该设备可能适用于那些对更传统的言语训练技术没有反应的儿童。
