Identification of open set words, by an experienced normal hearing subject using the tactile vocoder developed at Queen's University, was examined. The tactile vocoder filters and processes the acoustic waveform into 16 filter channels, each of which controls a vibrator on the skin surface. After acquiring a 250-word vocabulary through the tactile vocoder, the subject was presented with three sets of 1000 different open set words in three reception conditions. The percentages of words correctly identified in the tactile vocoder (TV), lipreading (L), and lipreading plus tactile vocoder (L + TV) conditions were 8.8, 39.4, and 68.7 percent respectively. Phonemic analysis of stimulus/response pairs revealed that 36.7, 64.9 and 85.5 percent of the phonemes were correctly identified in TV, L, and L + TV conditions, respectively, indicating that incorrect-response words often contained many correct phonemes. Also, syllabic stress of stimulus and response words was identical 88 percent of the time in the TV condition. Important information about speech was transmitted through the tactile vocoder.
研究了一名听力正常的受试者使用女王大学开发的触觉声码器识别开放集单词的情况。该触觉声码器对声波形进行滤波并处理成16个滤波通道，每个通道控制皮肤表面的一个振动器。在通过触觉声码器获取了250个单词的词汇量后，在三种接收条件下向该受试者呈现了三组1000个不同的开放集单词。在触觉声码器（TV）、唇读（L）和唇读加触觉声码器（L + TV）条件下正确识别单词的百分比分别为8.8%、39.4%和68.7%。对刺激/反应对的音素分析表明，在TV、L和L + TV条件下，分别有36.7%、64.9%和85.5%的音素被正确识别，这表明错误反应的单词通常包含许多正确的音素。此外，在TV条件下，刺激词和反应词的音节重音88%的时间是相同的。关于语音的重要信息通过触觉声码器进行了传递。
