Definitions
- the present invention relates to a data access system and method, and a voice browser.
- the Internet provides access to information and data resources on a scale which is unprecedented.
- the resources however are primarily limited to individuals who have access to a computer system with appropriate communications equipment and software that enables the system to connect to the Internet.
- the media continually refers to a current divide between the information rich and the information poor, being those who have access to the Internet and those do not.
- One way of addressing this divide and facilitate wider access to individuals is to move away from requiring the access system to comprise the traditional computer system.
- the telephone interface allows any person with a telephone to call the server and respond to voice prompts issued by the server by pressing keys of the telephone to forward the corresponding dual tone multifrequency (DTMF) signals for the server.
- DTMF dual tone multifrequency
- the DTMF responses received by the server are used to instruct the voice browser to access World Wide Web pages from the Internet.
- the voice browser on receiving web pages encoded in hypertext markup language (HTML) includes translation software to deconstruct the pages into voice data which is used to provide voice signals for the caller.
- HTML is a language which is designed to provide a visual display on a computer screen, and accordingly the various display elements cannot be correctly dealt with, if at all, by the translation software of the voice browser.
- the various video and image formats, such as MPEG and JPEG cannot be translated.
- a number of web sites utilise frames and tables in their HTML code which also gives rise to significant difficulties and complexity for the voice browser.
- the tendency for HTML pages is to include more and more visual elements, such as video and images, to attract users and this gives rise to significant difficulties for a voice browser.
- WAP wireless application protocol
- the forum and WAP is concerned with the delivery of data on a wireless network and, in particular, the ability of wireless devices, such as mobile telephones, to access data resources, such as those available on the Internet.
- the WAP protocol is used by microbrowsers stored on wireless devices to access data information encoded in a particular format for the WAP protocol, such as the wireless markup language (WML).
- WML is a content language specifically developed for wireless devices with limited text displays and which use prompt driven navigation to display text and command menus. WML therefore allows delivery of text which can be selected and requested using displayed prompts and the keys of a wireless device.
- HDML Handset Transport protocol
- HDML handheld device markup language
- HDML breaks text to be displayed on a wireless device into cards which can be moved between one another by selecting "accept” or “previous” keys on a handheld device.
- Soft keys are also available for inclusion in the cards to navigate between different cards based on display prompts. Data can also be keyed in on the wireless device in response to a received prompt and forwarded back to a HDTP server.
- a data access method including: connecting to a caller using a voice call path; receiving a request for data from said caller on said call path; sending said request to a location in a communications network determined by said request, said location including said data in a prompt navigation language; receiving and translating said data in said prompt navigation language into voice data; and converting said voice data to voice for said caller on said call path.
- the present invention also provides a data access system, including: means for connecting to a caller using a voice call path; means for receiving a request for data from said caller on said call path; means for sending said request to a location in a communications network determined by said request, said location including said data in a prompt navigation language; means for receiving and translating said data in said prompt navigation language into voice data; and means for converting said voice data to voice for said caller on said call path.
- the present invention also provides a voice browser stored on a computer readable storage medium, including: code for receiving a request for data from a user; code for sending said request to a location in a communications network determined by said request, said location including said data in a prompt navigation language; code for receiving and translating said data in said prompt navigation language into voice data; and code for converting said voice data to voice for said user.
- a "prompt navigation language” is a content language, such as WML or HDML, which includes text data followed by link data or prompt data, without visual layout data.
- Figure 1 is a block diagram of a preferred embodiment of a data access system with a voice browser
- Figure 2 is a flow diagram of steps executed by a call flow module of the system
- Figure 3 is a flow diagram of steps executed by a page translator of the system.
- a data access system includes an interactive voice response
- the IVR 2 has a call flow module 8, a page translator module 10 and a text to speech module 16 stored on the platform.
- the IVR 2 also includes a telecommunications interface 18 for terminating calls received from a caller using a voice terminal 4, such as a standard telephone, so as to complete and connect to a communications path 20 between the caller 4 and the IVR 2.
- the IVR 2 also has an ISDN interface 22 to provide a permanent ISDN primary rate connection 24 to the Internet 12.
- the IVR 2 is a standard IVR platform which includes the interfaces 18 and 22 and the text to speech module 16.
- the IVR may, for example, be the First Contact IVR produced by Scitec.
- the text to speech module 16 may be the Learnout and Hauspie Tru Voice module.
- the Internet 12 includes at least one server 14 which is able to communicate with the page translator 10 using a standard protocol, such as HTTP, and stores prompt navigation language data, such as WML or HDML data.
- the modules 8, 10 and 16 and the interfaces 18 and 22 provide a voice browser for use by a caller 4.
- the modules 8, 10 and 16 are preferably implemented by computer programs, but can be implemented entirely or partly by hardware circuits, such as an ASIC, and may also be distributed over different communicating systems, as would be understood by those skilled in the art.
- the call flow module 8 executes the steps described below with reference to Figure
- the module 8 uses the line interface 18 to establish a call with the caller 4 and connect to and complete the call path 20 at step 30.
- the call flow module may await receipt of an identifying pin or security password to determine that the caller is authorised before proceeding to step 32.
- the module 8 initialises a session with the page translator module 10 by forwarding an initialising message to the translator module 10.
- call flow 8 will receive a default home universal resource locator (URL) from the translator 10 at step 34, which is stored for the caller 4.
- Call flow 8 then instructs the translator 10 at step 36, to access and download the data of the page at the location on the Internet 12 designated by the stored URL.
- Call flow 8 forwards the URL in a get page message, and the translator 10 obtains the page which is deconstructs into a number of data elements.
- the translator 10 returns to the call flow module a total number of elements for the page.
- Call flow 8 sets an element number count el num to 0 at step 38. It then determines at step 40 whether the final or total element number has been exceeded for the currently requested page. This condition is a trap for an error and will normally always return false.
- step 42 the call flow module 8 instructs the translator 10, using a get element message, to obtain the element el num of the page.
- the translator 10 returns the data element and the text string of the element is forwarded, at step 44, to the text to speech module 16 for conversion into corresponding voice which is placed on the call path 20 for the caller 4 via the interface 18.
- the text strings of the data elements comprise voice data produced for the call flow module 8 by the translator 10.
- the call flow module 8 determines whether the element el num includes a prompt requiring return of a digit. If it does, operation proceeds to step 48 where voice delivery is halted and a prompt provided for entry of a single key press by the caller 4. The caller 4 then needs to press a key on the caller's terminal 4 connected to the path 20 so as to forward a DTMF signal corresponding to the key pressed to the call flow module 8 via the interface 18.
- the module 8 receives the signal corresponding to the single key press at step 50 which is returned in a get link message, at step 60, to the translator 10. The translator 10 responds to the get link message by returning a URL to the call flow module 8 which is received at step 62.
- the URL returned by the translator 10 is checked at step 64 to determine whether a null URL has been returned, in which case the existing page continues to be announced to the caller 4, as the call flow module proceeds to step 58. If the URL is not a null, then it is stored by the call flow module 8 at step 66 and operation returns to step 36 to download the page corresponding to the new URL.
- step 52 determines whether the element has a string prompt.
- a string prompt is one which calls for data entry by the caller so if the prompt is included in the element operation proceeds to step 54, where announcement to the caller is halted to await a sequence of key presses to be entered. The prompt will ask the user to enter the data used in the keys of the terminal and then press a final digit, such as "#".
- the call flow module 8 detects that a sequence of key presses have been fully entered at step 56, the data inputted is passed to step 60 for formulation in a get link message for the translator 10.
- the variable el num is incremented at step 58 and operation returns to step 40.
- the call flow module 8 will cease execution of the steps when the caller 4 disconnects from the call path 20.
- the page translator module 10 operates in response to the messages received from the call flow module 8 and executes the steps described below with reference to Figure 3.
- the translator 10 accordingly waits for a message from the call flow 8 at step 82.
- the message is stored at step 84 and action taken based on the form of the message is determined in steps 86, 90, 96 and 102.
- step 86 If the message is an initialising message, as determined at step 86, operation proceeds to step 88, otherwise operation proceeds to step 90.
- step 88 the translator 10 simply forwards a default home page URL to call flow 8 and operation returns to step 82.
- step 92 the translator 10 forwards a request for the page designated by the URL in the get page message to the Internet 12 via the interface 22.
- the URL is sent using HTTP to a web server 14 which stores content in WML or HDML.
- the page retrieved by the translator is WML or HDML page.
- WML and HDML pages only comprise text data followed by link data or text data followed by prompt data. No visual layout data can be included with WML or HDML pages. Formatting is also restricted corresponding to the restricted display requirements of wireless devices.
- the translator 10 deconstructs the downloaded page into a number of elements which comprise text data followed by link data or text data followed by prompt data. The number of elements in the page is then determined and forwarded to the call flow module 8 at step 94. Operation then returns to step 82.
- step 96 the translator 10 determines that the message is a get element message, operation proceeds to step 98, otherwise operation proceeds to step 102.
- the element designated by the el_num in the get element message is retrieved by the page translator and converted into voice data as a text string. Whilst the text in an element is simply placed in the text string, the link or prompt data in an element needs to be handled differently. For example link data including a URL to "CNN" is converted into a text string "press 1 for CNN or press 2 to continue” . A string in this format is recognised by the call flow module as being a "digit" prompt, in that it requires a single response by selection from a number of possible responses, such as a binary response set.
- prompt data of the page the data may comprise for example:
- step 104 the translator 10 determines the link designated in the get link message which includes data corresponding to DTMF signals returned by the caller 4.
- the get link message also includes the element number el_num for which the data has been returned from the caller. Using the element number, the translator is able to determine whether the return data corresponds to a link or a prompt. For a link, using the example described above, if a DTMF signal corresponding to 1 is returned then the URL for CNN is obtained from the element stored by the translator 10. If a 2 is returned, then the translator simply provides a null URL for the link.
- variable substitution may need to be made for the URL obtained from the corresponding stored element.
- the link URL is determined to be http://foo/cgi?DBW. The link URL determined at step 104 is then returned at step 106 to the call flow module 8, and operation returns to step 82.
- the call flow module 8 and page translator 10 provide an efficient voice browser which has a number of significant advantages.
- WML and HDML are languages which are used by wireless device microbrowsers
- content developers are able to develop content for these microbrowsers as well as for people with telephones who can dial the IVR platform 2. This content is therefore available to people who would ultimately not have had access to the content, because they do not possess a device with a microbrowser or a computer system with access to the Internet.
- HTML content can be written to take a voice browser into account, this is invariably not the case, whereas the content and flow of control are clear and well defined in prompt navigation content languages such as WML and HDML.
- the prompt navigation languages are efficiently utilised by the IVR 2.
- the translation of WML or HDML pages by the IVR 2 also does not introduce a significant processor load, and accordingly a larger number of simultaneous connections to callers 4 can be maintained without complex or expensive hardware.
- the IVR platform may also include a speech recognition module to process voice responses from callers 4 instead of DTMF signals sent in response to key presses.
