Seven normally hearing adults were trained in the use of a multiple-channel electrotactile speech processor for 70 hours over a 6-month period. Two training strategies were used on each of the subjects: (1) analytic-plus-synthetic (AS), and (2) synthetic (S). The speech perception abilities of the subjects were assessed with closed sets of vowels and consonants, open sets of words and sentences, and speech tracking, for the tactile-plus-lipreading, tactile, and lipreading conditions. The subjects were tested on three separate occasions: (1) at the beginning of the study, (2) after 35 hours of training, and (3) after a further 35 hours of training. Wilcoxon matched-pair signed-ranks (MPSR) tests showed that improvements observed with both the AS and S strategies were significantly (p less than .05) greater than zero for most tests and conditions. The Wilcoxon MPSR test showed that the difference in improvements between the training strategies was significant for only the vowel and consonant tests in the tactile condition.
七名听力正常的成年人在6个月的时间里接受了70小时的多通道电触觉语音处理器使用培训。对每个受试者采用了两种训练策略：（1）分析加综合（AS），以及（2）综合（S）。通过元音和辅音的封闭集、单词和句子的开放集以及语音跟踪，对受试者在触觉加唇读、触觉和唇读条件下的语音感知能力进行了评估。在三个不同的时间点对受试者进行测试：（1）在研究开始时，（2）在训练35小时后，以及（3）在再训练35小时后。威尔科克森配对符号秩和（MPSR）检验表明，对于大多数测试和条件，采用AS和S策略观察到的改善均显著（p小于0.05）大于零。威尔科克森MPSR检验表明，训练策略之间的改善差异仅在触觉条件下的元音和辅音测试中显著。
