Abstract:
A system for facilitating the administration of a network accessible file stored on a network computer by means of communication with a user over a telephone handset. The network computer storing the network accessible file, typically a Hypertext Markup Language (HTML) file for use in a web site, allows a user to dial in and, through the use of a telephone handset, modify, create, delete or exchange web pages comprising the web site. The network computer presents the user with a list of modifiable objects contained in a web page, through speech simulation software, and receives instructions identifying and modifying these objects by speech or Dual Tone MultiFrequency (DTMF) tones. Upon receipt of these instructions, the network computer generates a new HTML file to replace the modified HTML file.

Description:
FIELD OF THE INVENTION 
     This invention relates to the modification of network-accessible files performed via the telephone. In one specific aspect the invention relates to the modification of HTML files, or similar type files, by use of a telephone. 
     BACKGROUND TO THE INVENTION 
     Several methods of displaying networked images are known in the art. Particularly, the world wide web (WWW), a portion of the public internet, allows users to access and view an enormous number of web pages on a computing device, typically a personal computer (PC). 
     Recently, systems have begun to integrate the use of telephones and computing devices. One application of this is in the area of PC banking. In this example, a user can, through the use of the Public Switched Telephone Network (PSTN), connect to a bank&#39;s central computer via a telephone. Upon connection, a user is then presented with a number of preselected transactions to complete. The list of options is presented to the user in an audible fashion through either pre-recorded sound segments or text-to-speech engines operating on a text-based list. A user will select a transaction through tones created by the user&#39;s telephone. For example, the user may select to transfer funds between accounts. On recognition of these tones, the bank computer will transfer the funds between the accounts, as specified by the instructions received. After completing the transaction, a user can visit a bank&#39;s web site and query the status of the accounts involved in the transaction. The page displayed, in consequence to responding to the user&#39;s query, will reflect the results of the funds transfer transaction completed by use of the telephone. 
     The web page displaying the results of the user selected funds transfer transaction is generated from two sources. The first source is a web page template. A web page template is simply a web page that displays data fields that are populated from other data sources such as a database, for example, a Structured Query Language (SQL) database. The web page template effectively contains all the information displayed on the page—with the exception of the pertinent data—indicating the layout of the page, and the fields that are to be filled or populated. Upon receipt of a request to view account information, the banking system generates a web page, consisting of a combination of a web page template and account balance data corresponding to the transaction-updated balances of the accounts, and transmits this web page to the user over the public internet. The web page data is then converted into a graphical image by means of a web browser. 
     The banking system, described above, allows the user to perform tasks via the telephone, which, due to its portability (if wireless) and ubiquitousness, can be initiated from virtually any place on earth. Moreover, due to the increased use by the public of the WWW, users will often visit the same web page on a regular basis to access up to date information. However, the banking system only allows for the data which populates fields in a web page to be modified. The presentation and the pages involved remains static until an authorized user, typically a bank employee, accesses the web server, via computer, and modifies the contents of a web page or web page template. 
     Accordingly, it is desired to provide a method and apparatus for improved data image modification by users via telephone station apparatus control. It is also desirable that such an apparatus be adapted to perform in conjunction with the large installed base of common image viewers such as Netscape Navigators™ and Microsoft Explorer™. It is also desirable to allow for the modification of the overlaying template web page, in addition to the data populated the template and also the replacement, creation or deletion of web pages or web page templates by a user via a telephone station apparatus.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring to FIG. 1, a system embodying the invention is referred to as a web site server system  100 . Web site server system  100  is interposed between a switched network, which may be the Public Switched Telephone Network (PSTN)  102 , and data network  104 . Network  104 , which can be the public internet, a private network or intranet, or a combination of the two, is in turn connected to a computing device  106 . PSTN  102  connects telephone station apparatus  108  to the web site server system  100 . As is known to those skilled in the art, due to the convergence of the PSTN and the internet, an alternative system embodying the invention has station apparatus  108  and computing device  106  communicating with web site server system  100  over a common network, such as data network  104  or PSTN  102 . Similarly, telephone station apparatus  108 , depicted in FIG. 1, need not be device wired directly to PSTN  102 , but, in the alternative, could be a wireless communication device such as a mobile telephone or the like. Similarly, computing device  106  need not be physically connected to the data network  104 . Rather, as is known in the art, computing device  106  can be connected to data network  104  via an Internet Service Provider (ISP) through PSTN  102 , or can be connected through other means to data network  104  such as a cable modem, an Asymmetric Digital Subscriber Line (ADSL) connection, a wireless connection or the like. Similarly, while the preferred embodiment describes an implementation of the invention involving the WWW of the public internet, data network  104  could be a Local or Wide Area Network (LAN or WAN, respectively) or any other data network used to distribute files to a plurality of users. 
     FIG. 2 is a schematic diagram of computing device  106 . Computing device  106  consists of a personal computer (PC)  200  connected to display  210 , input device  208  and network  104 . Display  210  can be any type of display known in the art. Similarly input device  208  can be comprised of combinations of common input devices such as keyboards, mice, audio input devices, or other known input devices. PC  200  is comprised of a central processing unit (CPU)  204  interconnected to memory  206  and network interface  202 . CPU  204  can be an Intel Pentium™, Motorola PowerPC™ or other suitable processor capable of performing the operations necessary to connect PC  200  to a network such as the internet or more specifically the WWW. Memory  206  is comprised of volatile memory, including Random Access Memory (RAM), and non-volatile memory, such as a hard disk drive or Read Only Memory (ROM) or preferably a combination of the these types of memory. Network interface  202  can be a network interface card such as an Ethernet or Token Ring network card, or a modem that connects to network  104  through the PSTN and an Internet Service Provider. PC  200  is also capable of reading removable media  212 , which may be a diskette, CD-ROM or other method of transferring data to memory  206  of PC  200 . As is known to those skilled in the art, computing device  106  is not limited to the embodiment described above, but can be modified to come within the spirit and scope of this invention. 
     Memory  206  contains the software programs and data necessary to enable computing device  106  to connect and communicate with data network  104 , such as the WWW. Memory  206  is comprised of data  220 , applications software  230  and operating system  240 . Operating system  240  preferably includes a graphical user interface such as Microsoft Windows 98™ or the Macintosh Operating System 8™. Application software  230  is comprised of: communications suite  222 , which includes means for connecting to data network  104 , and may include TCP/IP, PPP, SLIP, Ethernet or Token Ring software protocols; graphical image browser  224 , such as Netscape Navigator™, Microsoft Internet Explorer™, Mosaic™ or other commercially available browsers (including, if desired, text based browsers such as Lynx™); and other applications  226 . 
     FIG. 3 is a schematic of web site server system  100 . Similar to computing device  106 , web site server system  100  consists of a computer server  300  optionally connected to a display  316  and input device  314 . Computer server  300  is a networked computer connected to network  104 . Server  300  is also connected to PSTN  102 . Input device  314  and display  316 , while optional, may consist of similar devices corresponding to input device  208  and display  210  of computing device  106 . 
     Computer server  300 , as is common in the art, is typically a Reduced Instruction Set Computing (RISC) device such as a Sun Microsystems UltraSparc™ Station, or an IBM RS/6000™ computer. However, computer server  300  may also be a PC such a Compaq Proliant or IBM NetFinity™ server or any other computer suitable for hosting web pages and connecting to the internet, either directly, or through the PSTN. Computer server  300  is comprised of CPU  304 , typically a Sun UltraSparc™ CPU, Motorola or IBM PowerPC™. CPU, or Intel Pentium™, Pentium II™ or Pentium Pro™ CPU; interconnected with Analog to Digital (A/D) Converter  306 , Digital to Analog (D/A) converter  308 , memory  310 , network interface card  302 , and PSTN interface  312 . Network interface card  302  is connected to network  104 , and may be an ethernet, token ring, ATM card, T 1  interface or any other suitable means of communication with a data network to support access of a web page by a user. PSTN Interface can be a plurality or bank of modems connected to PSTN  102 , an ADSL card or similar analog to digital communications device capable of receiving voice-calls made over the PSTN or similar communications network. Memory  310 , which is in communication with CPU  304 , consists of a combination of volatile and non-volatile memory, typically RAM, ROM and hard disk drive or optical storage device, used to store data, software applications and an operating system. AID Converter  306  is any suitable device capable and suited to convert voice signals, received by computer server  300  from PSTN  102 , into a digital representation operated on by processor  304 . Similarly D/A Converter  308  is a device capable of producing audio signals that are recognizable by a typical user as speech. A/D converter  306  and D/A Converter  308  are typically combined into a single device called a ‘codec’ (e.g. the Motorola MC 145481 PCM Codec-Filter) which combines anti-aliasing filtering with the A/D and D/A conversion hardware. Computer server  300  is also capable of reading removable media  318 , which typically is a CD-ROM, diskette or other removable media, sufficient to transfer software or data to computer server  300 , generally, and memory  310  specifically. 
     Referring to FIGS. 3,  4  and  5 , memory  310  of computer server  300  is logically divided into three portions, namely operating system  400 , application software  420  and data  410 . Operating system  400  of computer is preferably a multitasking operating system such as Unix, Linux, Microsoft Windows NT™, Sun Solaris™ or IBM AIX™. However, an operating system capable of hosting a web site, connecting to the PSTN, and performing the coordinating and performing the operations disclosed below is sufficient. Application software  420 , stored in memory  310 , is further subdivided into PSTN application software  426  and network interface software  424  and IP suite  422 . PSTN application software  426  enables receipt of voice telephone connections made by a user to computer server  300  over PSTN  102 . Network interface software  424  enables the operation of network interface  312  and maintains communication between the user, via computing device  106 , and computer server  300  over data network  104 . IP Suite software provides the communication protocols, namely the Internet Protocols are described in RFC 1011, which is maintained by the Network Working Group of the IETF (Internet Engineering Task Force), the contents of which are hereby incorporated by reference, and is designed to facilitate communication between computer server  300  and computing device  106  over data network  104 . Together PSTN application software  426 , network interface software  424  and IP Suite  422  comprise communications software  430 . 
     Memory  310  of computer server  300  also stores other applications  428  which are necessary for the functioning of web site server system  100  embodying the invention. Other applications  428  consists of synthetic speech software  500 , speech recognition software  502 , DTMF Tone recognition software  504  and web server/hosting software  506 , as shown in FIG.  5 . Synthetic speech software  500  includes text to speech software which, in conjunction with D/A converter  308 , operates to convert digital text into a corresponding analog signal, which, when received by telephone station apparatus  108 , will be converted into an audio signal simulating speech to the end user. Such a text to speech system is commercially available in Lernout and Hauspie&#39;s L&amp;H TTS3000/TSO, a software package that runs under Windows 95 and NT. “Synthetic Speech” can also be implemented using playback of pre-recorded speech fragments which are concatenated together to form sentences. This provides a more natural sounding user interface than Text to Speech provides. This technology is preferred for playing out voice prompts. Whereas reading out the actual textual content of a web-site is better served by Text to Speech. Speech recognition software  502 , such as Nortel Network&#39;s OpenSpeech product or 3C the SpeechWorks Recognition Engine from Applied Language Technologies Inc. (ALtech) operates in conjunction with computer server  300 , to convert an analog signal into commands or instructions recognizable by computer server  300 . The analog signal, representative of a user&#39;s speech, is generated by telephone station apparatus  108  and transmitted to computer server  300  over PSTN  102 . DTMF Tone Recognition software  504 , such as is provided by Nortel&#39;s Meridian Application Server product, specifically via the MPC-8 DSP Card, operates, in conjunction with A/D Converter  306 , to recognize the tones produced by telephone station apparatus  108 . Web server software  506  operates to store, retrieve and transmit web pages, and receive and fill user requests pursuant to these functions. Examples of web server/hosting software  506  is Apache&#39;s web server software and Microsoft Internet Information Server. 
     As an option, a single unit which may be used to provide the telephone interface, codec, and DSP-based DTMF tone recognition software is the Dialogic D/41ESC “International SCSA 4-port Voice Processing Board”. This is an ISA board which plugs into a PC. 
     Data  410  comprises the third portion of memory  310  of computer server  300 . Data  410 , as shown in FIG. 6, is comprised of user access data  600 , object types  602 , electronic files, such as web pages and web templates  604 , and other miscellaneous data  606 . User access data  600  stores data corresponding to users authorized to access and modify a web site hosted by computer server  300 . User access data  600  contains user passwords; the various access rights granted to individual users, such as the web pages  604  that can be modified; the specific objects contained in those web pages that can be modified by individual users; a user&#39;s authorization to create, delete or exchange web pages and other security measures that are enabled to ensure that only authorized users of the web site server system  100  modify the web site hosted therein. Object types data  602  stores the various objects that can be inserted into a web page. This includes text objects, audio or video clip objects, graphic image objects, link objects, operation objects and other objects that may be presented on a web page as well as formatting instructions. Web pages and templates  604  comprise the web site hosted by web server software  506  on computing device  300 . The portion of memory  310  designated other data  606  includes sufficient memory for operating system  400  to perform routine tasks of web site server system  100 . Other data  606  is used for caching memory, the creation of temporary files, that a person skilled in the art understands to be necessary for the normal functioning of a computer, such as computer server  300 . 
     The person skilled in the art will recognize that the distinction between operating system  400 , application software  420  and data  410  is artificial and is described in this form for clarity and ease of understanding. Moreover, application software  420  is also artificially separated into software components  422 ,  424 ,  426 ,  500 ,  502 ,  504  and  506 . It is well known to persons skilled in the art that several of these functions can and are embodied in a single software program and that several of these programs can be incorporated into operating system  400 . As such, various combinations of software and a variety of demarcations between software packages that perform the operations described above are within the scope and spirit of this invention. 
     In overview and referring to FIGS. 1-7E, server system  100  receives a request for connection from a user calling server system  100  from telephone station apparatus  108 . Server system  100 , upon receipt of the connection request, establishes a connection with telephone station apparatus  108  (S 702 ). Server system  100  receives identification data from telephone station apparatus  108 , and determines, by accessing user access data  600  of memory  310 , the identity and rights and privileges of the user associated with the identification data received (S 704 ). Server system  100 , generates a list of web pages stored in web page memory  604  that are accessible in light of the identification data received by the system (S 706 ). Server system  100 , generates a digital signal simulating speech, by means of text to speech software  500  operating on the list of web pages authorized to be altered, which is then-passed through D/A Converter  410  to generate an analog signal. This analog signal is transmitted to telephone station apparatus  108  over PSTN  102  where it is converted into an audio signal that simulates speech. The speech simulated corresponds to identifiers, such as titles, of the list of web pages that are alterable in light of the identification data received by server system  100 . Server system  100  then receives a request from telephone station apparatus  108  to select (S 708 ) and alter a web page (S 710 ). If data is received by server system  100  that corresponds to a request to modify the web page, operations  800  (FIG. 7B) are performed by server system  100 . If the request corresponds to deleting the selected page, operations  900  (FIG. 7C) are performed by server system  100 . Similarly, requests for exchanging the selected web page with a second selected web page are fulfilled by the performance of operations  1000  (FIG.  7 D). A request for the creation of a new web page is fulfilled by server system  100  by performing operations  1100  (FIG.  7 E). The alterations to the web site hosted by server system  100  are then accessible to all authorized users as disclosed below. 
     In greater detail, in S 702 , server system  100  establishes a connection, on request from a user, with telephone station apparatus  108 . The connection request is received by server system  100  on receipt of a telephone call from station apparatus  108  made over PSTN  102 . Upon the establishment of the connection, which is accomplished by operation of the PSTN Interface  312 , server system  100  establishes the user&#39;s identity and access privileges in S 704 . The user&#39;s identity is established by recognizing the user&#39;s voice, through the co-operation of the A/D Converter  306 , PSTN Interface  312  and speech recognition software  502  in S 704 . A user&#39;s voice or a series of words is stored in user access data  600  of memory  310  as an identifier for a particular user. In an alternative embodiment, upon connection (S 702 ) a user is prompted to enter, via the keypad of telephone station apparatus  108 , an access code. This access code, comprised of DTMF tones, is received by computer server  300  wherein DTMF Tone Recognition software  502  compares the DTMF access code received from the telephone station apparatus  108  via PSTN with the codes stored in user access data  600  to identify a particular user. In either embodiment, upon recognition, comparison and validation of the security code input by the user, computer server  300  accesses web page data  604  and user access data  600  to determine the web pages that the identified user has been granted authority to modify, create, delete or exchange (S 706 ). The user is then presented with the list of web pages, by server system  100 , for which access has been granted. The list of alterable web pages identified by server system  100  could also include a dummy entry for the creation of a new web page which the user may wish to create. The presentation of the list of web pages is accomplished through the operation of text to speech software  500 , D/A Converter  308  and PSTN Interface  312 . From the list of web pages identified, an analog signal is generated and transmitted to telephone station apparatus  108  over PSTN  102 . At telephone station apparatus  108 , the analog signal received is converted into an audio signal that simulates speech. The analog signal received by telephone station apparatus  108  corresponds to the web pages&#39; titles, or other page identification data, of the list of web pages identified as alterable by the user by server system  100 . The simulated analog speech signal is a translation of a digital signal generated by the operation of text to speech software  500  operating on the list of web pages identified by server system  100  as being alterable by the user, which is then passed to D/A Converter  308 . D/A Converter  308  converts this digital signal into an analog signal which is then transmitted to PSTN  102  through PSTN Interface  312 . Upon presentation of the list of alterable web pages, server system  100  awaits receipt of data selecting a web page (S 708 ). A selection request may be input either by DTMF tones, which may correspond to a number associated with the web pages contained in the list, in which case DTMF Tone Recognition software  504  would be accessed and used by CPU  304  of computer server  300 , or by receipt of spoken instructions repeating the title, or other unique identifier, corresponding to a web page in the list of web pages generated by server system  100 , In the latter case the spoken instructions received would be recognized by operation of speech recognition software  502 . Upon receipt of the instruction in S 708 , server system  100  prompts for an instruction to modify, delete, create or exchange the web page selected (S 710 ). A user responds to this prompt by the input of a DTMF tone or a speech command, which is identified as described above. 
     Upon receipt of a request to modify an existing page of the web site hosted by server system  100 , server system  100  performs operations designated  800  of FIG.  7 B. In S 802 , server system  100  reviews the contents of the web page, selected in S 708  for which a modification request was received in S 710 , and presents the user with a second list. This second list consists of the objects that can be modified by the user, based on the access rights contained in user access data  600 , which are contained in the identified and selected web page. This second can also include a dummy entry to allow for a user to insert a new object into an existing web page. As aforenoted, the objects may comprise various objects that can be inserted into a web page. This includes text objects, audio or video clip objects, graphic image objects, link objects, operation objects and other objects that may be presented on a web page as well as formatting instructions. The second list is, as described above, converted into an analog signal simulating speech by server system  100 , by co-operation of CPU  304 , speech to text software  502 , D/A converter  308  and PSTN Interface  312 , that is transmitted over PSTN  102  to telephone station apparatus  108 . The analog signal is then converted into an audio signal by station apparatus  108 . Upon presenting the second list to the user, server system  100  awaits a user selection of an object to modify. The user inputs a selection request into telephone station apparatus  108  either through use of the keypad of telephone station apparatus  108  or through speech. Upon receipt of this request, server system  100  identifies the object in the web page selected by the user for modification (S 804 ). Regardless of input method, that is speech or DTMF tones, server system  100  prompts the user to modify either the underlying object type or the object data that characterizes the selected object type (S 806 ). By way of explanation, an object is composed of two parts, namely an object type and object data. An object type represents the various objects that can be inserted into a web page. As aforenoted, object types include text objects, audio or video clip objects, graphic image objects, link objects, and operation objects. The object data is data characterizing the object type. The link object data would be data characterizing the link object and would include address data (URI) and format data that characterizes the link object&#39;s format on the web page, including font size, colour, position, etc. For example, a user may have requested to modify a link object. A link object is an object type that represents a hyperlink that can be displayed on a web page. If the user wishes to modify or replace the underlying object, with another type of object, the user would select to modify the object type. With such a selection a user could, for example, replace the link object with an image object. An example of where a user may wish to modify the object type may be where a Uniform Resource Identifier (“URI”) is no longer valid, for instance if the web page indicated by the link has been deleted or moved. The user, in such an instance, may wish to replace a link object with a text object, and accompanying text data, notifying users that the previously available link has been deleted. However, if the user wishes, for example, to modify the data, rather than the object type, relating to the underlying object, in this example the link object, the user would select to modify the object data. With such a selection, a link on a page would remain but its formatting and the URI to which the link points can be modified. Furthermore, as aforenoted, the list of objects that can be replaced in the selected web page may include a dummy entry which would allow the user to insert a new object in the selected web page. 
     If server system  100 , in S 806 , receives a request to modify the object type, server system  100  presents the user a list of object types that can be inserted in place of the object originally selected by the user in S 804  (S 808 ). The list presented to the user is generated by server system  100  by accessing object types data  602  stored in memory  310 . The object type list, once generated, is presented to the user in the manner described above. In S 810 , server system  100  receives a request for and identifies a new or second object type to replace the first object type identified in S 804 . Server system  100  then prompts the user to populate the object type selected with object data in S 812 . 
     If, in S 806 , a request is received by server system  100  to modify the object data, rather than the object type, server system  100  then only performs the operations described in S 812 . In S 812  server system  100  receives, through speech or DTMF tones, or a combination of the two, object data that is associated with the object type selected in S 804  or S 808 . This object data may, for example, include text generated by server system  100  from the speech of the user; the position on the web page based on numbers indicated by DTMF tones generated by the telephone station apparatus  108 ; the selection of a file, for an audio, video or graphic clip or image, selected from a list of such flies generated by the server system  100  in the manner described above; or other data necessary to sufficiently characterize the object type selected in S 804  or S 810 . 
     Once the object type selected in either S 804  or S 810  has been sufficiently characterized, the user is prompted by server system  100 , in S 814 , for further modifications. If server system  100  receives data, again in the manner described above, indicating that further modifications are requested, then in accordance with S 814 , operations  800  are repeated. Once all modifications and operations  800  have been completed, S 712  (FIG. 7A) is performed. In S 712  server system  100  generates a second HTML file, or similar graphic image electronic file, capable of being distributed and accessed over data network  104 , based on the first electronic file, namely the web page selected by the user altered in accordance with the modifications completed in operations  800  made to the page selected in S 708 . This newly created or modified file is also stored in web page data  604  of memory  310 . Server system  100  then prompts the user to indicate, again through speech or DTMF tones, whether further pages are to be modified (S 714 ). If server system  100  receives a request, again through speech or DTMF tones, that other pages are to be modified, operations  700 , with the exception of S 702  and S 704 , are again performed. If no further pages are to be modified the connection with the user is terminated (S 716 ). 
     In S 710 , a request to delete the web page, selected in S 708 , on the web site hosted by server system  100 , may be received. If such a request is received, operations generally designated  900  (FIG. 7C) are performed. Server system  100  prompts the user to indicate whether hyperlinks (or links) on the web site which have a URI pointing to the web page selected for deletion are to be modified (S 902 ). If data received by server system  100  indicates that the links are not to be modified, then the page identified in S 708  (FIG. 7A) is simply deleted from memory  310  of computer server  300 . However, if server system  100  recognizes, through speech or DTMF tone input, that the internal links should be modified, server system  100  identifies and presents to the user, through text to speech software  500 , a list all links on the web site that have a URI indicating the web page selected for deletion in S 708 . Server system  100  then receives and recognizes, through speech or DTMF tones, data that is to replace the URI data contained in the link objects identified by server system  100  (S 906 ). The data corresponding to the link objects identified is then modified by server system  100  in accordance with the data received by server system  100  (S 906 ). This modification of the link object data could also include the removal of the link object from those pages containing the identified links. In an alternative embodiment, all links presented to the user in S 904  need not be modified in the same way. Server system  100 , if the user so desires, could modify each link separately with new link data or delete individual or all links identified by server system  100  in S 904 . Upon completion of the link object and link object data modifications, server system  100  deletes the page identified by server system  100 , in S 708 , from web page data  604  of memory  310  (S 908 ). Upon deletion of the page selected in S 708  (S 908 ) the system then, if data is received from the user indicating such an instruction, generates a default web page with the same URI as the web page deleted in S 908  (S 910 ) indicating that the previous web page has been deleted. The default web page is stored in web page data  604  of memory  310 . S 910  is performed to ensure that users desiring access to the previous page (through bookmarks, hyperlinks not contained in the web site hosted by server system  100 , or through hyperlinks in the web site hosted by server system  100  which were not modified during the performance of S 902 ) are not given an error message but a warning that a change has taken place. Upon completion of S 910 , operation S 714  is performed. As described above, server system  100  prompts the user for an indication of whether other web pages are to be modified (S 714 ). If data is received by server system  100  indicating that no further modifications are requested, the connection between telephone station apparatus  108  and server system  100  is terminated (S 716 ). If other modifications are indicated by the data received by server system  100 , operations  700 , with exception of S 702  and S 704 , are performed. 
     If data is received by server system  100  in S 710  that indicates that two web pages are to be exchanged then operations generally designated  1000  of FIG. 7D are performed. Operations  1000  may be performed to allow for web pages, prepared by a user in advance of an event occurring, to be exchanged upon the occurrence of the event through use of a telephone. For example, a user may generate a web page that is ordinarily not accessible by visitors to a web site. For instance, a police force may generate a web page listing emergency contact telephone numbers in case of a natural disaster, such as flooding. While this page may or may not be ordinarily available, it is not, ordinarily, the first page a visitor to a police force&#39;s web site will view. However, once a state of emergency has been declared, it may be desirous to exchange the police force&#39;s main web page with the emergency contact web page. Regardless of the rationale for requiring such an exchange, the operations performed are the same. In performing operations  1000 , server system  100  identifies and generates a list of web pages, which is presented to the user through use of text to speech software  500 , that the user has access and is allowed to exchange with the web page selected in S 708 . Upon receipt of data, indicated by either speech or DTMF tones, a second web page is identified (S 1004 ). The URI for each web page identified in S 708  and S 1004  is then exchanged (S 1006 ). As described above, further modifications may be performed (S 714 ) or the connection with the user will be terminated by server system  100  (S 716 ). 
     Should the data received in S 710  indicate that a new web page is to be created then operations, generally designated  1100  of FIG. 7E, are performed. Server system  100  identifies and generates a list, which is presented to the user as in S 802 , of object types available to the user (S 1102 ). Upon receipt of data, in the form of speech or DTMF tones, indicating the object type to be inserted in the new web page (S 1104 ), the object type selected is characterized by data, such as text, formatting information and the like, by further data received by server system  100  from the user (S 1106 ). Server system  100  then inquires and receives data from the user indicating whether additional objects are to be added to the new web page (S 1108 ). Upon receipt of data indicating that no further additions are required, a second web page, or other graphic image capable of being transmitted and accessed over a data network, is generated based on the first electronic file, or web page, selected in S 708  and altered in accordance with the data instructions received through the performance of operations  1100  and stored in web page data  604  of memory  310  (S 712  of FIG.  7 A). Server system  100  then requests whether additional pages are to be altered (S 714 ), and if no further alterations to the web site hosted by server system  100  are indicated, server system  100  terminates the connection with the user (S 716 ). 
     FIG. 8 illustrates an exemplary method of reviewing or viewing of the alterations made by server system  100  illustrated in FIGS. 7A-7E and is generally designated operations  1200 . A connection, on request of a user, is established between server system  100  and computing device  106  over data network  104  (S 1202 ). Typically, a request is made by computing device  106 , operating under operating system  240 , such as Microsoft Windows 98™, via input device  208  in conjunction with browser application  224 , such as Netscape Navigator™. Upon receipt of this request, server system  100 , by means of application of web server software  506 , fulfills this request by transmitting a web page, stored in web page memory  604  of computer server  300 , to computing device  106  via data network  104  (S 1204 ). Computing device  106  receives the transmitted data (S 1206 ) and a graphic image is generated by browser  224  by interpreting the transmitted data (S 1208 ). The transmitted data is typically in the form of Hypertext Markup Language (HTML) files. The graphic image generated in S 1208  is then displayed on display  210  of computing device  106 , in the manner known in the art. The image displayed on display  210  will reflect the alterations made by server system  100  in performing operations  700 - 1100  (FIGS.  7 A- 7 E). 
     As will be understood to those skilled in the art, the hardware components of computer server  300  and PC  200  need not be separate components as described and illustrated. As is known in the art, two or more of the components of each computing device could be combined in a single Application Specific Integrated Circuit (ASIC) chip. Similarly, as described above, the demarcations between software components of computer server  300  and PC  106  are shown for ease of understanding and could be combined into a smaller number of software applications and provide the same functionality. Moreover, the disclosed system is not limited to HTML files, but the system could also be adapted to SGML, XML or other languages used to generate graphic images for distribution over a network. 
     Those skilled in the art will understand and appreciate that the steps of the method disclosed in FIGS. 7A-7E and FIG. 8 need not be performed in the same sequence or in their entirety to fall within the spirit and scope of the claims. Similarly, data transmitted to server system  100  in the form of speech or DTMF tones can, in the alternative, be transmitted in DTMF tones or speech, respectively, or through a combination of the two forms. Further, it will be understood that the teaching of the invention will equally apply to telephone system which use other than DTMF tones to transmit keypad entries. 
     It will be further understood that the invention is not limited to the embodiments described herein which are merely illustrative of a preferred embodiment of carrying out the invention, and which are susceptible to modification of form, arrangement of parts, steps, details, and order of operation. The invention, rather, is intended to encompass all such modification with its spirit and scope, as defined by the claims.
