Telephone Speech Standards Committee Descriptive Document PROB LEM DES CRIPTION PROPOSED BY Speech is poised to become a mass-market interface for over-the-phone applications. At the present time, those companies interested in implementing a speech system face several key challenges: 1. End-User Challenge: Speech provides a new and larger set of capabilities to the user, and can improve the quality of the user interface over touch-tone interactions. However, speaking to systems is unfamiliar to users, and each system is different - requiring users to learn how to use each one individually. A greater degree of predictability in the interface would likely reduce the end-user's learning curve, speeding adoption and increasing the user's comfort level. Touch-tone systems have not had the benefit of interface standards, and user confusion about the meaning/function of certain "keys" on the keypad is not uncommon. 2. Developer Challenge: To date, speech interactions have been designed by a small set of skilled designers, with varying design techniques. As speech becomes a real mass market interface option, we need a set of proven interface practices that can be employed by developers with little or no expertise in speech. Availability of a set of user interface standards will
