Abstract

A voice activated wireless locator service provides an interactive voice response system whereby a user is walked through a sequence of voice prompts to select a desired destination. Using either geo-coded information provided during the voice call or speech recognition of a shortcut phrase associated in a database with a street address, and using a locator service database, the system can provide spoken instructions using a text to speech engine, providing the name, location, and driving directions to one or more destinations matching the criteria provided by the user. Because the system uses speech recognition technology, it is particularly well suited for wireless access devices, such as cellular telephones, which are often used when a user is engaged in other activities, such as driving. Once the location information and driving directions are retrieved and provided vocally to the user, the same information can be provided in a text format using a WAP data connection and a database access synchronized to the voice activated database entries.

Claims

1. A method of providing voice activated locator services to a user using a wireless access device, comprising:

accepting a voice connection between the wireless access device and a speech serves;

initiating a call flow in which voice prompts are provided to the user and the user'"'"'s spoken responses are received;

converting the user'"'"'s spoken responses into database query commands;

forwarding the database query commands to a locator service, along with starting location information;

receiving destination information from the locator service;

converting the destination information into a voice prompt and presenting same to the user over the voice connection;

converting the destination information into a graphical representation and presenting the same to the user over a data connection between the wireless access device and a WAP server;

providing a starting location voice prompt to the user requesting starting location information;

receiving a spoken shortcut phrase from the user in response to the starting location voice prompt;

converting the spoken shortcut phrase to a text phrase;

comparing the converted text phrase to a plurality of pre-stored test phrases;

identifying a pre-stored text phrase matching the converted text phrase; and

forwarding the street address associated with the identified pre-stored test phrase as the starting location information.

2. The method of claim 1 wherein the graphical representation is text.

3. The method of claim 1 wherein the destination information includes driving directions.

4. The method of claim 1 wherein the destination information is stored to a database along with a unique identifier.

5. The method of claim 4 wherein the unique identifier is the Mobile Identification Number of the wireless access device.

6. The method of claim 1 wherein the location information for the wireless access device is obtained by cellular site triangulation.

7. The method of claim 1 wherein the user'"'"'s spoken responses are in the form of a type and a subtype for a desired destination.

8. The method of claim 1 wherein the starting location information is geo-coded information for the actual location of the wireless access device.

9. The method of claim 1 wherein the database query commands are forwarded over a computer network.

10. The method of claim 1 further comprising the step of a user placing a voice call between the wireless access device and the speech server, using the wireless access device.
