Abstract
The present invention describes a system and method for enabling a caller to obtain access to services via a telephone network by entering a spoken first character string having a plurality of digits. Preferably, the method includes the steps of prompting the caller to speak the first character string beginning with a first digit and ending with a last digit thereof, recognizing each spoken digit of the first character string using a speaker-independent voice recognition algorithm, and then following entry of the last digit of the first string, initially verifying the caller's identity using a voice verification algorithm. After initial verification, the caller is again prompted to enter a second character string, which must also be recognized before access is effected.
