Abstract

A system and method for constructing phrases for delivery by a media server over a network to a client. Upon initiation of a session an initial ordered play list comprising a plurality of identifiers is conveyed to the media server. Each identifier on the ordered play list is associated with an audio prompt file constituting a prerecorded audio message, an audio component file comprising a component of a variable audio message to be conveyed to the client or a identifier list comprising at least one identifier. Each identifier contains information sufficient to fetch the content associated with the respective identifier from another server. The media server utilizes the first identifier on the ordered play list to fetch the content associated with that identifier from a server specified by the identifier and removes the respective identifier from the ordered play list. The media server then determines whether the retrieved content is an audio file. If the retrieved content comprises an audio file, the file is played to the client. If the file comprises an identifier list, the identifier list is inserted at the top of the current ordered play list and the media server continues to fetch files associated with the respective identifiers on the ordered play list in sequence. This process continues until no more identifiers are present on the ordered play list. Once the play list has been exhausted, the audio message comprising any prompt files and variable data to be played to the client has been communicated over the network.

Claims

1. A media server for delivering audio information to a client, said client being communicably coupled to said media server by a communications network, said media server comprising:

a processor;

a computer program; and

a memory communicably coupled to said processor, said memory being operative to store said computer program,

said processor executing said computer program out of said memory;

a. to obtain an ordered play list comprising at least one identifier, each of the at least one identifier identifying one or more of a location and a name of an associated target object, at least one associated target object being a list of at least one additional identifier, each of the at least one additional identifier identifying one or more of a location and a name of an associated target object;

b. to sequentially fetch the target object associated with each of the at least one identifier in the ordered play list;

c. to determine whether said obtained target object is an audio file or the list of at least one additional identifier;

d. if the obtained target object is an audio file, to forward said audio file to said client over said communications network to play the audio file to said client; and

e. if the obtained target object is the list of at least one additional identifier, to insert the obtained at least one additional identifier in the ordered play list as the next identifier for which the associated target object is to be sequentially fetched.

2. A method of delivering audio information from a media server to a client over a communications network, said media server including a processor, a computer program, and a memory for storing said computer program, said memory being communicably coupled to said processor, said method comprising the steps of:

a) executing said computer program, by said processor, to obtain an ordered play list including at least one identifier, each of the at least one identifier identifying one or more of a location and a name of an associated target object, at least one associated target object being a list of at least one additional identifier, each of the at least one additional identifier identifying one or more of a location and a name of an associated target object;

b) executing said computer program, by said processor, to sequentially fetch the target object associated with each of the at least one identifier in the ordered play list;

c) executing said computer program, by said processor, to determine whether the obtained target object is an audio file or the list of at least one additional identifier;

d) if the obtained target object is an audio file, executing said computer program, by said processor, to forward said audio file to said client over said communications network to play the audio file to said client; and

e) if the obtained target object is the list of at least one additional identifier, executing said computer program, by said processor, to insert the obtained at least one additional identifier in the ordered play list as the next identifier for which the associated target object is to be sequentially fetched.

3. The method of claim 2 wherein the target object associated with each of said at least one identifier on said ordered play list is one of (i) an audio component file comprising a component of an audio variable stored on an audio server, (ii) an audio prompt file stored on a prompt server or (iii) a list of at least one additional identifier to retrieve associated target objects.

4. The method of claim 3 wherein said prompt server and said audio server comprise a single server.

5. The method of claim 2 further including the step of executing said computer program, by said processor, to process said audio file in advance of said step of executing said computer program to forward said audio file to said client over said communications network to play the audio file to said client.

6. The method of claim 5 wherein said step of executing said computer program to process said audio file includes the step of decompressing the respective audio file in the event said obtained target object is an audio file.

7. The method of claim 5 wherein said step of executing said computer program to process said audio file includes the step of transcoding said audio file in the event said obtained target object is an audio file.

8. The method of claim 2 wherein each said at least one identifier includes a Universal Resource Identifier (URI) identifying one or more of the location and the name of the associated target object.

9. The method of claim 8 wherein said step of executing said computer program to sequentially fetch the target object comprises the step of retrieving the target object over a TCP/IP based local area network.

10. The method of claim 8 wherein said step of executing said computer program to sequentially fetch the target object comprises the step of issuing an hypertext transfer protocol (HTTP) request to the respective URI included in the respective identifier and receiving an HTTP response containing content associated with the respective URI.

11. The method of claim 10 wherein said HTTP response includes a MIME type indicating that the HTTP response includes an audio file or a URI list and said step of executing said computer program to determine whether said obtained target object is an audio file or a list of at least one additional identifier includes the step of analyzing the MIME type of the respective HTTP response.

12. The method of claim 8 wherein said step of executing said computer program to sequentially fetch the target object comprises the step of retrieving the target object over a TCP/IP based wide area network.

13. The method of claim 12 wherein said TCP/IP based wide area network comprises the Internet.

14. The method of claim 2 further including, prior to said step of executing said computer program to obtain said ordered play list, the steps of:

generating said ordered play list in a play list generating server; and

executing said computer program, by said processor, to utilize said ordered play list from said play list generating server in said media server.

15. The method of claim 14 wherein said play list generating server and said media server comprise a single server.

16. The method of claim 14 wherein said step of generating said ordered play list includes generating said ordered play list at least in part in response to an input provided by said user.

17. The method of claim 16 wherein said input comprises an indicator of a specific language to be employed in the selection of audio prompt and audio variable files specified by said identifiers.

18. The method of claim 16 wherein said input comprises an indicator of a geographic locality communicated by said user.

19. The method of claim 16 wherein said input comprises an indicator of a currency to be employed in the selection of audio prompt files and audio variable files specified by said identifiers.

20. The method of claim 16 wherein said input comprises a voice input provided by said user.

21. The method of claim 16 wherein said input comprises a touch-tone input responsive to selections by said user.
