Although automatic speech recognition (ASR) can provide a medium of controlling computers which is relatively easy to use, novice users often have problems with it during their initial practices. In this study, two methods for training subjects to use ASR are compared. One group of subjects received a short demonstration given by an experienced ASR user and the other group received verbal instructions on how to use the device. The results show that subjects given a demonstration achieved better performance than those given instructions (p< 0.005). This is explained by virtue of the fact that the successful use of ASR requires procedural knowledge which is better acquired through some form of practice than through instruction. It is concluded that a demonstration provides 'practice by proxy'. 'Task like' forms of enrolment are discussed. It is suggested that although they can provide the possibility of practice, they are not applicable to all types of ASR use. A demonstration provides users with task familiarization, and an appropriate style of speech. |
