Telephone speech standards committee descriptive document

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.
