Automated computer telephone interviewing (ACTI) is a technique by which a computer with speaker-independent voice recognition capabilities asks respondents a series of questions, recognizes then stores the answers, and is able to follow scripted logic and branch intelligently according to the flow of the questionnaire based on the answers provided, as well as information known about the participant. This technique is also referred to as interactive voice response (IVR).
