Description: This research examined voice recognition performance as a function of time and showed no decrement in performance after 21 weeks. In addition, vocabulary sizes up to 240 utterances showed stable performance. Two people also combined their voice reference patterns and were then able to achieve an error rate of less than 2% when either person spoke to the speaker-dependent voice recognition unit. (Author)
