Abstract

A method of funneling user responses in a voice portal system to determine a desired item or service includes (a) establishing an attribute value associated with a particular attribute of a desired item or service and (b) determining if the attribute value satisfies an end state. If the end state is not satisfied, steps (a) and (b) are performed with a new particular attribute.

Claims

1. A computer-implemented method of operating an interactive user operated Internet voice portal having established multiple predetermined vertical domains of interest and a hierarchy of attributes within each vertical domain of interest from top to bottom, the method comprising operations of:

responsive to a user placing a telephone call to the voice portal, a processor identifying the user and obtaining user selection of a vertical domain of interest;

a processor performing funneling operations comprising;

(a) building a vocabulary set containing top-level attribute values appropriate to the selected vertical domain of interest;

(b) querying the user to choose a top-level attribute value, applying speech recognition to user responses where recognized answers are limited to contents of the vocabulary set;

(c) until a bottom level attribute value is chosen, repeatedly performing operations comprising;

(1) building an updated vocabulary set containing attribute values appropriate to the latest chosen attribute value, and (2) querying the user to choose a next-lower-level attribute value and applying speech recognition to user responses where recognized answers are limited to contents of the updated vocabulary set;

responsive to a bottom level attribute being chosen, a processor conducting an Internet search of HTML non-voice sources for prescribed types of information pertaining to the chosen bottom-level attribute value and, unassisted by voice extensions and enhancements to said HTML, audibly providing resultant information to the user via the telephone call.

2. The computer-implemented method of claim 1, where:

the funneling operation is performed if the voice portal has not previously stored any attribute value preferences of the user for the selected vertical domain of interest;

the funneling operation is additionally performed if the voice portal has previously stored any attribute value preferences of the user for the selected vertical domain of interest, but the user has opted to override the stored attribute value preferences.

3. The method of claim 1, where:

the funneling operation is only performed if the voice portal has not previously stored any attribute value preferences of the user for the selected vertical domain of interest;

the operations further comprise, if the voice portal has previously stored any attribute value preferences of the user for the selected vertical domain of interest, instead of the funneling operation, a processor performing an operation of conducting an Internet search for prescribed types of information pertaining to the stored attribute value preferences.
