Final answer:
A robocall is an automated phone dialer that delivers prerecorded messages. They face challenges such as legal restrictions, possible respondent errors, and changing phone usage habits.
Step-by-step explanation:
The term used to describe a type of automated phone auto-dialer that delivers a personalized, prerecorded message to recipients is a robocall. These robocalls are often used for a variety of purposes including political campaigns, public service announcements, and marketing. However, they can have limitations such as potential error if respondents press incorrect keypad numbers, misunderstandings of the questions, lower response rates, and legal restrictions like the Telephone Consumer Protection Act that prohibits automated calls to cell phones. Additionally, recent challenges have emerged due to changes in phone usage habits such as increased use of caller ID, decreased use of landlines, and the hectic nature of personal schedules leading to decreased willingness to be interviewed.
