Abstract

A voice activated telephone directory and call placement system accessible over a telecommunications network allows a caller to store a personalized telephone directory, and to retrieve a selected directory listing therefrom by speaking a series of voice entries. In response, the system selectively provides a voice rendition of a destination telephone number associated with the listing and optionally initiates dialing of the number.

Claims

1. A method of operating a telecommunications network for providing a voice-activated telephone directory, the network having the capability of routing calls thereover and for processing caller-spoken, voice entries, said method comprising the steps of:

(a) storing a plurality of caller-associated telephone directories including the step of storing voice templates of a plurality of callers speaking respective directory listings;

(b) organizing said listings as part of respective subsidiary directories having respective subsidiary directory names with said subsidiary directories included as part of respective subdirectories having respective subdirectory names;

(c) storing voice templates of the callers speaking said respective subdirectory and subsidiary directory names;

(d) receiving a telephone call over the network from a caller in response to the dialing of a directory access telephone number associated with the caller'"'"'s directory;

(e) verifying the identity of the caller and, in response, retrieving said directory associated with the caller;

(f) receiving a caller-spoken entry, comparing said entry with said subdirectory name template of said directory associated with the caller, and determining whether said entry matches said subdirectory name template;

(g) if a match is determined between said entry and subdirectory name template, comparing a subsequent caller-spoken entry with said subsidiary directory name template included as part of said subdirectory, and determining whether said subsequent entry matches said subsidiary directory name template;

(h) if a match is determined between said subsequent entry and subsidiary directory name template, comparing an additional caller-spoken entry with said listing template, and determining whether said additional entry matches said listing template; and

(i) if a match is determined between said additional entry and listing template, retrieving said listing-associated telephone number.

2. The method as set forth in claim 1, said verifying step including the steps of receiving a caller-spoken entry of the passcode, comparing said entry with a previously stored voice template of the caller speaking a passcode, determining whether said passcode entry matches said passcode template.

3. The method as set forth in claim 2, said verifying step including the steps of using the caller'"'"'s social security number as said passcode and decoding said passcode entry independently of the speaker thereof in order to retrieve said passcode template.

4. The method as set forth in claim 1, further including the steps of storing a plurality of directories organized into a plurality of groups, assigning a directory access telephone number to each of said groups, and providing access to a directory included in one of said groups in response to the dialing of said directory access telephone number assigned thereto.

5. The method as set forth in claim 1, further including the step of naming said subsidiary directories as the letter of the alphabet corresponding to the first letter of the respective listing included in said subsidiary directories.

6. The method as set forth in claim 1, further including the step of identifying said subdirectory as a specific type of subdirectory.

7. The method as set forth in claim 6, said specific type of subdirectory including one of a personal directory, business directory, company directory, and city/state directory.

8. The method as set forth in claim 1, further including the steps of providing voice prompts over the network to the caller in order to prompt the caller to speak said entries.

9. The method as set forth in claim 1, further including the step of providing a voice rendition of said telephone number to the caller.

10. A method of operating a telecommunications network for providing a voice-activated telephone directory, said network having a capability of routing calls thereover and for processing caller-spoken, voice entries, said method comprising the steps of:

(a) storing a plurality of subdirectories organized into a plurality of directories;

(b) assigning a predetermined telephone number to each of said directories;

(c) providing access to a directory in response to a caller dialing said telephone number assigned to said directory;

(d) comparing a caller-spoken entry received over said network with a previously stored voice template of said caller speaking a subdirectory name identifying a subdirectory included as part of said directory associated with said telephone number, and determining whether said spoken entry matches said subdirectory name template;

(e) if a match is determined between said entry and name template, comparing a subsequent, caller-spoken entry received over said network with a previously stored, voice template of said caller speaking a directory listing organized as part of said subdirectory, and determining whether said subsequent entry matches said directory listing template; and

(f) if a match is determined between said subsequent entry and said directory listing template, retrieving a destination telephone number previously stored in association with said directory listing.
