Abstract
ABSTRACT A telecommunications system and method is disclosed which introduces events into a current voice call of a telephone between at least two telephone users in a telecommunications network. The event is typically an audio file which can be introduced into the current voice call, in response to an event initiated by one of the telephone users. The invention can also be employed with Interactive Voice Response (IVR) systems for delivering audio, visual and translated information to a user in a telecommunication network. The invention is particularly suitable for use in Telecommunication Relay Services (TRS) systems. In another embodiment the invention provides a way of convertin g audio data to a visual representation and vice versa for telecommunication users.
Description
A Telephone System and Method Field of the Invention The present invention relates to a method and system of introducing events into a current voice call. In particular the invention relates to a method and system which utilises an Interactive voice response (IVR) system for delivering audio, Visual and translated information to a user in a telecommunications network.
Background to the Invention Interactive Voice Response (IVR) systems collect data in conjunction with a voice call.
The data may include information such as an account number. This data may be used to retrieve information from a server related to the caller. The IVR is usually implemented on a client’s system, which is coupled to the server. There are many hundreds of IVR systems in operation. There is no standardisation of hardware or operating systems.
Many of the proprietary systems have the capability to interface with the intemet. Some systems can receive an input from the intemet and output to a non-connected system such as an SMS to a mobile telephone.
Other IVR systems use inputs from the intemet to set up a voice call to a phone. This typically involves Computer Telephone Integration (CTI), Private Branch Exchange (PBX) or other switching mechanism. The human agent or call assistant will typically receive the user’s telephone number over the intemet and then call the user directly over a direct telephone connection. There is no connection between the intemet and the telephone call. In some cases, the human agent and the caller can interact using a web server to share information.
Telecommunication Relay Services (TRS) utilise a typical IVR system. TRS is a service which provides Deaf and Speech Impaired individuals access to normal telephony services. TRS and variants of the TRS principles are available in many countries. The current technical solution for provision of V0" tele hony services to Deaf and Speech Impaired individuals is to involve a human intermediary usually called a Communications Assistant (CA). The primary purpose of a CA is to read text input from one party of a telephone call and relay or voice that text out to the other party. A CA will also listen to a speaking party and relay that information as text to the other party. A CA is currently involved in all voice based TRS services. TRS voice telephony can be accessed by either a Computer connected to an IP Relay service via the intemet, or a "ITY machine connected to a standard telephone line. However a problem with this service is that TRS is not reliable as it is limited to a CA been available at the time a user wishes to make a call. The service is very expensive to maintain. Users of the service feel their privacy is compromised by the necessity of a communications assistant. Another problem is that it is difficult to have a meaningful communication session as there is a time lag by using the CA. A different CA can be connected to a user each time a connection is made making the user uncomfortable to a strange voice of the CA. The TRS service is limited to the language skills of the CA, in many cases the CA can only communicate in one language. Similar problems exist for hearing impaired or deaf individuals as the user must type the complete text. The CA must voice the text to the hearing person. The hearing person must reply to the CA, then the CA must type the complete response to the user.
The above problems can equally be applied to language translation call services.
Currently a human interpreter must be available who can interpret between two languages. Such interpreters are rarely available on demand 24 hours a day 7 days a week.
US patent publication number US2003/0005076 ‘Bellsouth Intellectual Property Corporation’ discloses an IVR system which provides a Visual Interactive Voice Response (VIVR) system for delivering information to a user during a VIVR session, comprising a VIVR Server operative to send voice-based information to a telephone and to send visual-based information to a networking device, in response to the receipt of a VIVR session request and a session identification number. A database operative is required to maintain a VIVR session identification number (session ID), which identifies the telephone and the networking device. This system requires an AIN (Artificial Intelligent Network) system. This system only works when the Voice and Data connections are on the same network, which is a limitation. This will not function with all telephones worldwide. The session identification number is generated automatically by the VIVR/AIN. This system cannot guarantee to automatically generate a unique session ID for instance when the data component originates on a corporate LAN, and the Voice Component originates behind a corporate PBX. The system requires access to the session ID database by components on the AIN this is not a practical solution, as the VIVR system also claims to identify the networking device and uses the IP address, the Internet directory number and the Voice directory number.
This system assumes only one user per Voice communications channel. The function and scope of this system is limited by access to a predetermined number of network configurations.
Existing IVR systems maintain a continuous telephone connection. Another problem with sending information, in particular, for example, audio files, is that it takes time to transfer or stream audio files over the internet and the transmission time is dependent on the available bandwidth in the network. In general telephone systems have a guaranteed bandwidth to facilitate conversation. Existing problems in the music industry is the problem of music piracy wherein songs are downloaded illegally from the intemet.

Brief Description of the Drawings The invention will be more clearly understood from the following description thereof, given by way of example only, with reference to the accompanying drawings, in which: Figure 1 is an overview of the present invention, Figure 2 is a layout of the architecture of the IVR system and Figure 1 Figure 3 is an alternative embodiment of the present invention, Figures 4 and 5 is an application of the present invention for voice translation, Figures 6 and 7 is an application of the present invention for text to speech translation, and Figure 8 illustrates an alternative architecture of the present invention for a deaf LISCF.
Detailed Description of the Drawings Referring now to Figure 1, there is illustrated an overview of the present invention, indicated generally by the reference numeral 1. A call initiator 2, in the form of a user with a telephone and a computer connected to the intemet, makes an intemet 6 connection to a server 3. The call initiator 2 then uses a telephone to call a call recipient 5 via an interactive voice response (IVR) system 4 over atypical telephone network 7, for example a PSTN. There are two technical components of every voice call, the caller’s own telephone number (CLI) and the recipient’s telephone number (ODN). The invention utilises these components to route the output of the intemet commands via the IVR system IE 04 00 4 to the corresponding telephone connections in a reliable manner. These two components can be entered in a text box by the call initiator 2 on the computer in a text box of a web page.
The IVR system 4, if instructed by the call initiator 2, will connect the caller to the call recipient 5. Again, the call recipient 5 will have the telephone and a computer with an intemet connection. The call initiator 2 and the call recipient 5 can now converse as per a nOfl’Il'c1l COllV€TS3lIlOIl.V Ideally the sewer 3 is a HTTP server which can employ Secure Socket Layer (SSL) or other encryption mechanisms when required by the application. The server 3 can also perform FTP functions when applicable to an application required. The present description discusses a user which can be the call initiator 2 or call recipient 5. The call initiator and recipient 2,5 are depicted in figure 1 as having access to both a telephone and a computer connected to the intemet for illustration purposes. It will be appreciated to the person skilled in the art that the telephone and computer Could form one device, for example an internet enabled mobile telephone. Therefore, it is envisaged that the present invention can be carried out on a single device that provides both voice call and intemet connection capabilities. A voice call should be interpreted broadly to encompass any voice call over a communication network to include both land and wireless voice connections.
In operation, the call-initiator 2 is connected to the web server 3 via a computer intemet connection. The call initiator 2 makes a voice call which is routed via the interactive voice response system 4 to the call recipient 5 over the telephone network 7. While the caller is connected to the server 3, the caller can instruct the IVR system 4 to deliver or play sounds over the current telephone connection. This is achieved by clicking an icon or hyperlink on the computer screen, having the intemet connection to the web server 3. The clicking of the icon triggers an event to instruct the IVR system 4 via the web server 3 to deliver or play an audio file over the telephone connection. Similarly, the call recipient 5, if is connected to the web server 3, can also instruct the IVR system 3 to play audio files over the same telephone conversation. The net result is that one or both parties of the voice call can introduce external sounds in real time to the conversation, as required, as long as they are connected to the web server 3 in real time. l\) U\ IE 04 00 It will be appreciated that all commands relevant to an IVR application and it’s functions can be placed visually on a web page, which can be seen by both the call initiator 3 and the call recipient 2. When the call initiator 2 clicks the icon or hyperlink, the IVR system 3, connected to the user’s telephone, responds immediately. The web page can be updated in response to the user’s choices. When the call initiator clicks the relevant link on a web page, the audio file is played in real time over the telephone connection irrespective of the original audio file size. This is because the audio file is associated with the IVR system 4 or can stored directly on the IVR system 4. Therefore, it is not necessary to download the audio file over the telephone connection but simply play the audio file down the telephone line. This ensures instant response means because when the user for example clicks "yes" on the web page, the audio file "yes" is played over the telephone instantly. It will be appreciated that the telephone connection does not have to be limited to two callers. As the file name together with the unique identifiers called the ‘event data’ is only being transmitted from the web server 3, it is normally only a fraction of the size of the actual audio file. It will be sent irrespective of the user’s intemet bandwidth. All audio files are stored on the IVR system 3 or retrieved from another source to the IVR. This means that each event is triggered and carried out in real time. It has been found that a particularly suitable means of providing the voice call is over a VoIP voice channel.
Figure 2 is the same as figure 1 except the IVR system is shown in more detail. Typical IVR systems are designed to accept DTMF input from a connected voice telephony channel and use this input to execute instructions according to a software program assigned to that channel. The program will normally instruct a Call Control mechanism 400 — 405 to access and play an audio file to a caller listening to that voice channel by means of a telephone handset. In the case of IVR systems configured to accept Voice or audio input, the software program may be a Fax or Voice XML application. The Call Control module 402 is a representation of several standard telephony features common to IVR systems. Among these features is the facility to route an incoming voice channels to specific destinations by software commands, access and play audio files through one or more voice channels simultaneously or route the input for further processing. In each case the user input to the IVR originates from a telephone device connected to at least one voice channel on the IVR. Telephone devices are normally IE 0400 limited to 12 touchtone keys, there are 16 DTMF tones 0-9, *, #, A, B, C, D. (Ref: ANSI Tl.40l—l988 Section 7.2).
The configuration shown in figure 2 provides an alternative method of providing user input to the IVR and outputting the assigned program responses in real time to a callers listening and speaking through designated voice channels on the IVR. This is achieved by: Submitting the user input in the form of data over the internet.
Receiving the input data at a server connected to the IVR.
Formatting and relaying this ‘event data’ to a Call Data management module on the IVR.
The Call Data management module 401 contains a data table of all currently active voice channels and status information pertaining to those channels on the IVR. When the event data ‘identifier field’ references an active voice channel it will trigger an action within the Call Data management module 401 which will instruct the Call Control system to execute a program according to further instructions contained in the event data.
If the event data module 400 an identifier field contains no reference to an active voice channel it will either activate a new voice channel if valid instructions are contained in the event data or perform no action and return the call status through the server to the client. Figure 2 illustrates two users 2,5 connected to each other via the IVR. Both users 2,5 can speak and hear a per a normal voice telephony conversation. If the event data submitted by either user over the internet contains a valid channel identifier then that event may be output through the associated voice channels to one of the parties or both parties simultaneously. Either party can submit data a long as the channel Identifier corresponds to an active voice channel referenced in Call Data management module 401. The event data module 400 can contain several data fields amongst which are the following : A: Channel identifier field This a unique identifier in order to effect the program response through correct voice channels associated with the program.
IE 04 00 B: The data field This will normally contain the filename of an audio file accessible by the Call Control system. This field may also contain text data input by the user.
C: Call status field This data contains information pertaining current status of voice channels identified by the channel identifier. Call status data is returned to the client computer and can be visually displayed. l0 D: Connection field: This data contains instructions which when interpreted by the associated program will instruct the Call Control system to perform many standard IVR functions, including connecting and disconnecting channels and routing channels to alternative destinations. Setting up conference facilities or retrieving data from an alternative source and system.
E: language IN field In the case of text input applications this field will indicate in which language the user is inputting text.
F: language OUT field In the case of text input this field will indicate the requested output language of the text translation and audio files H: Gender field This will indicate that the user has requested the audio files be played in either a male or female voice. l: Routing field This will define the preferred routing of text and audio for processing, as well as defined storage folders for text and audio files.
IE 0400The Event data module 400 can contain a multitude of data fields, which can initiate programs, which can control all IVR functions and applications. The call control management 401 controls an audio file module 405 which delivers audio to either the incoming call or outgoing call connection 403,404.
It will be appreciated that the invention can be implemented to control the output from any current IVR system 4 via a web interface as illustrated in figure 3. When a telephone is connected to the IVR system 4, the internet based output can be interpreted by the IVR system 4 as a telephone key press and used to control telephone based IVR applications.
The invention will present each menu level in a visual form on a web page. The user can call the IVR application using a normal telephone or mobile phone. When the user clicks on the web page, the invention will send text data corresponding to an individual or series of DTMF tone to the IVR system 4 via the web server 3. The IVR system 4 will interpret the text and user’s telephone application and will respond according to the equivalent telephone keypad pressed by the user. The user can then Visually navigate the IVR system 4 menu structure in a much more ergonomic manner. This is particularly applicable to mobile phones as they do not need to be removed from the ear in order to press the keypad.
The users calling line identifier (CLI) can be stored on the web page. Subsequent data submissions from the web page will include an identifier based on the CLI information.
The user dials a specific number to access the IVR system 4. The CLI data, together with the dialled number to the IVR system, provides a method of routing the output of the server 3 via the IVR system 4 to the correct telephone connection. Additionally it is possible for the IVR system 4 to connect to other IVR systems 4a to access other information in response to an event initiated by the call initiator 2. In this case audio files representing valid DTMF tones are played by the IVR system 4 to the telephony input of IVR system 4a.
It will also be appreciated that each user accessing the same IVR application will have an activated CLI to generate a unique identifier. It will be appreciated that other identifiers beside CLI can be used as long as the web interface and IVR application are in compliance with this identifier. Other identifiers can be uses to generate the unique identifier for example the Out Dialled Number (ODN), a cookie associated with one of the users, an IP address or a browser script. These identifiers can be entered separately on the web page [\) ‘J! IE 04 00and entered on the telephone keypad when requested by the IVR program, associated with the IVR system 4. Software stored on the IVR system 4 can then maintain a direct link between requests made on a web page and outputs to the correct telephone connection.
It is also possible for the IVR system 4 to send a unique identifier directly to the user, which can be shown or hidden. If they do not enter any telephone number it is possible to show this identifier to the user and use the voice connection to request the user to enter this identifier by keying in numbers on the telephone handset, which is then used as the identifier.
Alternatively the IVR system 4 can inform the user over the voice call to enter an identifier on the webpage. This identifier would relate to the current voice channel the caller is using and uniquely identify event data from the internet.
The invention provides for music listening without downloads as illustrated in figure 3.
Currently, it is possible to call a special number and listen to sample track of popular songs and music. The caller is requested to enter several key presses before the required audio is played over the phone. This is cumbersome and limited to twelve phone keys. The invention will allow the caller to interact visually with the available tracks by presenting the audio application as visual information on the users device. A user can send an intemet application to a first IVR system 4, which links to a second IVR system 4a storing the music application. The selected audio application from the second IVR system is converted to visual information at the second IVR system, for example in the form of a menu. This menu is presented on the users device. The user can select an option from the menu which triggers the delivery of an audio application over the voice call to the user. This is achieved by the user by selecting a portion of the visual information by clicking the appropriate icon or hyperlink on the users device or computer. The user can listen to the music over the current voice call without actually downloading the music application.
Referring now to Figures 4 and 5, indicated generally by the reference numerals 20 and 30 respectively, there is identified a language translation application of the present invention.
The caller selects a phrase to send, in this case "how are you today". The web server 3 receives the corresponding file name only, for example, FR1005. The web server 3 sends IE 04 00the file name to the IVR system 4. The IVR system 4 recognises the file name and plays the matching audio file over the appropriate telephone connection to both parties. The audio file played over the telephone connection is a pre—recording of "comment allez vous aujourd’hui". The result is that the English speaker has asked the recipient "how are you today". The recipient hears only "comment allez vous aujourd’hui", the direct translation of "how are you today" into French in real time.
The French speaking caller recipient 5 connected to the intemet wishes to reply to the phrase "comment allez vous aujourd’hui" and selects the phrase "je vais bien, et vous".
The corresponding file name, for example, eng2345 is sent over the intemet to the web server 3. The file name eng2345 is sent to the local IVR system 4. The IVR system 4 recognises the file name and plays the matching audio file over the appropriate telephone connection to both parties. The audio file played over the telephone connection is a pre- recording of "I am well, and you?’’. The result is that the French speaker has replied to the English phrase "how are you?". The English speaker hears only "I am well, and you?".
Referring now to Figures 6 and 7, indicated generally by the reference numerals 40 and 50, illustrate a text to speech with a translation application. The speech impainnent application includes the facility by which a user can input the text of the audio file to be played using a computer keyboard. Then using a text—to-speech (IT S) system the resulting audio file is played over the associated live telephone connection. Nonnally, a speech impaired person will click icons on a web page and the pre-recorded audio will be played over the current telephone connection. There will be occasions when the user will need to express something which is not available as a pre-recorded audio file. In this instance, the user can type the required text on the web page. A search is performed on the IVR system 4 to determine if an audio file matching the text is available. If a match is found on the audio file, it is retrieved and played immediately by the IVR system 4 over the telephone line. If no match is found, the text is submitted for processing to the text-to-speech system 51.
The resulting TTS audio file will be delivered to the IVR system 4. The TTS audio is immediately played over the telephone to the connected users. The audio file and text is stored on the IVR system for future and subsequent use. Subsequent text matches will access and play the pre-recorded audio file immediately. Therefore, it will not need to be processed again by the TTS system. A user can choose to change the audio output, for ,_r UI IE 04 00 example, from a male to female voice.
Referring again to Figure 6, a user submits text to be converted to audio in a chosen language. The user can type the required text on the web page and submit it to the server 3. In this case, the text is first translated into equivalent text in the language specified by the user 41. The translated text is sent to the TTS system 42, specified for that language.
The resulting translated audio output is played by the IVR system 4 over the associated live telephone connection.
A status protocol is provided between the IVR system and the telephone users, for example by means of CGI, ASP or other scripts on the server 3 which can interrogate the call data management module 403 of the IVR system 4. The results of the interrogation can be formatted and returned via the server 3 to the user as call status information . The protocol can be configured to visually indicate to the users the status of a current voice call via the users computer. This is important for deaf users who cannot hear whether a voice connection has been made. Additionally the invention provides a visual indication procedure to establish a call. For example, a hearing impaired person can click pre—defined icons or input to a text-to-speech system 51, illustrated in figure 7, when using the present invention. The resulting audio will be played over a connected telephone system to the call recipient. In this case, speech coming from the recipient into the IVR system 4 can be sent to a speech—to—text system. This will output a text string corresponding to the words spoken by the recipient. This text output is then viewed by the hearing impaired person on the connected computer. All the time during the call connection the status can be visually indicated to the hearing impaired or deaf user.
Figure 8 illustrates an alternative architecture of the present invention for use in a TRS service by a hearing impaired or deaf user. For Hearing impaired or Deaf individuals the proficiency of a communications assistant (CA) is improved. IP Relay services are faster with reduced latency. One of the problems of TRS services for Deaf individuals is the conversation latency caused by the requirements of : a) The User needs to type the complete text. b) The CA must Voice the text to the hearing person. l\} U: ie 0400 c) The hearing person to reply to the CA d) The CA must then type the complete response to the User.
By implementing the present invention a CA is no longer required to voice the text to a hearing person. This affords the opportunity for the CA to improve relay speeds by applying Speech Recognition software without interfering with the conversation flow. This can significantly improve text input when compared to typing. Speech recognition requires less CA training than that required for a typing proficiency of 60 words per minute. The perception of privacy is improved as neither the IP relay user or the hearing recipient is directly aware of the CA. The sex of the CA is not relevant, the user can choose a male or female TTS (Text to Speech) output. Users can store frequently used phrases. The output voices are consistent and recognisable to regular recipients such as friends and families of TRS users.
It will be appreciated that while IVR systems have been discussed in this specification other telephone switching mechanisms can be used.
It will be appreciated that the present invention improves the overall efficiency of the Telecommunications Relay Service for speech impaired individuals. The caller can choose a male or female voice at will. TRS services may not always have CA of the requested sex available. Users can choose to input text in another language, without the need for a CA conversant in that language. Users can store frequently used phrases such as name, address, or TRS explanations and information. There is a greater perception of privacy as there is no third party involved in the conversation. The output voices are consistent and recognisable to regular recipients such as friends and families of TRS users.
