User enters application.

Disclosed is a method of assigning passwords for users to speak to gain entry to a speech-enabled application. The fundamental concept is to provide randomly selected passwords to users, drawing the passwords from a pool of passwords known to have good recognition accuracy.

Some speech-enabled applications require a user to provide a password to enter the application. In some cases, this entry to the application depends on correct recognition of the user's name followed by a spoken password or DTMF PIN. The DTMF PIN has the advantage of not relying on a probabilistic process such as speech recognition, but is a less natural way for a user to interact with a system. Relying on correct recognition of a user's name and a user-generated password puts the system at risk because proper names are among the most difficult types of tokens for a system to recognize, and allowing users to generate their own passwords opens the

Using the disclosed method, a system automatically assigns a password to a subscribed user, and...
