Overview
Several studies have compared the effects of use of totally speech based and totally text based interaction. [[1]] concludes that participants’ repetitions of commands were more frequent when speech was used for both the user production and reception modes rather than text.
IVR - short for Interactive Voice Response - is the technology that automates the interaction with telephone caller. Historically, IVR solutions have used pre-recorded voice prompts and menus to present information and options to callers, and touch-tone telephone keypad entry (popularly known as DTMF) to gather caller response. Modern IVR solutions now enable input and responses to be gathered via spoken words with voice recognition.
