Psychological Factors Influencing Response Preferences Using Speech Technology as an “On-Line Interviewer”

Users may not always desire natural language exchange with speech-capable systems. Regression and analysis of variance techniques were used to examine the choice of words vs. numbers as preferred speech input mode in response to items on two psychological tests presented by computerized voice output. Psychological factors were found to relate to response preference. This exploratory analysis suggests that additional designed experimentation assessing the psychological aspects of speech technology would prove interesting.
