My experiences have identified a number of issues that cause users to exit VoiceXML applications. For example, users will abandon an application - even if they like its concept - when they: are confused by their initial contact with it; think the application stopped working; encounter errors; don't quickly perceive the application's value; and become bored with long prompts or unwieldy application navigation. Your VoiceXML application can avoid or address these issues - and retain more first time users - by implementing human factors wisdom in the context of a UCD (user centered design) process.
