## Title
Systems and methods for providing instant messaging to TDD/TTY users

## Abstract

Instant messaging (IM) is provided between a TDD/TTY user and an entity. The user may use a TDD device to initiate a call with the entity. One or more converters may convert a TDD message from the user's device to IM, which is then provided to a recipient of the call, such as a representative of a company. The converter(s) may also convert IM from the representative into a TDD message that may then be provided to the user on the TDD device.

## Background
BACKGROUND
Currently, hearing-impaired users communicate with representatives of entities, such as financial services companies, through TDD (telecommunications devices for the deaf) and TTY (telephone typewriter) devices. This process requires a third party to relay information between the user and the representative. The third party receives TDD/TTY signals and verbally relays the information to the representative, and then receives spoken information from the representative and provides it via TDD/TTY to the user. This often leads to confusion for the hearing-impaired user and the representative. Additionally, the presence of a third party, unknown to the user, presents potential security concerns for the user.
As an example, Telecommunications Relay Service (TRS), is an operator service that allows people who are hearing-impaired to place calls to standard telephone systems via TDD/TTY, personal computer, or other assistive telephone devices. A common type of TRS call involves a call from a person who is hearing-impaired and utilizes a TDD/TTY to a person who is not hearing impaired and can both hear and speak. In such a call, typed messages are relayed as voice messages by a TRS operator, and vice-versa. This allows callers who are unable to use a standard telephone to be able to place telephone calls to people who use a standard telephone, and vice-versa. When the person who is hearing is ready for a response, it is customary for that person to say “Go Ahead” or “GA” to indicate that it is the TDD/TTY user's turn to talk, and “Stop Keying”, “SK”, or “Ready to hang up” when it is time to hang up, and vice-versa. Hence, this process is time-consuming, expensive, and may be frustrating for both the calling party and the recipient of the call.
SUMMARY
Instant messaging (IM) is provided between a TDD/TTY user and an entity. The user may use a TDD device to initiate a call with the entity. One or more converters may convert a TDD message from the user's device to IM, which is then provided to a recipient of the call, such as a representative of a company. The converter(s) may also convert IM from the representative into a TDD message that may then be provided to the user on the TDD device.

DETAILED DESCRIPTION
FIG. 1 is a block diagram of an implementation of a system that provides instant messaging (also referred to herein as IM) between a TDD/TTY (also referred to herein as TDD) user and a recipient of a call from the TDD/TTY user. Instant messaging is a form of real-time communication between two or more parties based on typed text. Instant messaging uses an instant messaging client that connects to an instant messaging service. Many IM clients are known, such as Microsoft's Windows Messenger, Yahoo's Instant Messenger, and AOL's Instant Messenger.
A connection 15 is established between a TDD device 10 and an entity 20. A user may use the TDD device 10 to initiate a call with the entity 20, or vice-versa. The TDD device 10 may be any known TDD equipment or electronic device for text communication via a telephone line, or any computing device that has been equipped to emulate the functionality of a TDD device. A typical TDD device is about the size of a small laptop computer with a keyboard and small screen to display typed text. In addition, TDD devices commonly have a small spool of paper on which text may be printed. The text is transmitted live, via a telephone line, to a compatible device, e.g., one that uses a similar communication protocol. As described herein, the text transmitted by a TDD device is converted to an IM protocol. An example computing device is described with respect to FIG. 8.
The entity 20 may be a company, such as a financial services company or bank, for example, that comprises one or more converters 22 that convert a TDD message to IM, and IM to a TDD message, described further below. The converter(s) 22 may convert a TDD message from a user's device 10 to IM, which is then provided to the recipient of the call, such as a representative 30 of the entity 20. The converter(s) 22 may also convert IM from the representative 30 into a TDD message, which may then be provided to the user on the TDD device 10. The conversions may be performed by the same converter device and/or module or by different converter devices and/or modules. Various TDD protocols and various IM protocols, described further herein, may be supported and may be used interchangeably.
In an implementation, one or more representatives 30 are associated with the entity 20, and may have one or more computing device(s) 25 on which to receive and transmit IM messages. The entity 20 may also comprise one or more computing device(s) 25 that may operate in conjunction with software modules 27 and one or more data storage device(s) 29. The storage device(s) 29 may contain user information that had been previously received and stored, e.g., with respect to a user's accounts. This data may be personal information such as the user's marital status, age, address, account information, etc., for example, and may be used to confirm the identity of the user or to personalize data pertaining to the user that is presented to the representative. An example computing device is described with respect to FIG. 8.
Software modules 27 are shown that may be used in the performance of the example techniques described herein in conjunction with the other various elements and components described herein. Example software modules include modules for maintaining a connection between a user and a representative, retrieving user and other data from storage, performing conversions and translations between various protocols, packaging information for transmission, and generating information that may be useful to the representative and the user, described further herein. While specific functionality is described herein as occurring with respect to specific modules, the functionality may likewise be performed by more, fewer, or other modules. The functionality may be distributed among more than one module.
As noted above, a connection 15 is established between the TDD device 10 and the entity 20. The connection 15 may comprise a telephone network, a local area network, a wide area network, the Internet, or any combination thereof, for example.
FIG. 2 is an operational flow of an implementation of a method that provides instant messaging between a TDD user and a recipient of a call from the TDD user. The recipient may be a representative of an entity, such as a financial services company or a bank, for example.
At operation 200, a user places a call through a TDD device to the entity. A representative associated with the entity is notified that the incoming call is from a TDD device, at operation 210. The notification may be in the form of a displayed window, message, or other indicator on the representative's computer monitor or display, or it may be a notification over the representative's telephone, for example. In an implementation, a button, icon, or link, for example, is provided that the representative can select to answer the call and begin an instant messaging conversation with the user.
At operation 220, the representative generates an instant message in answering the call. The instant message may request authentication information from the user, or may be another type of greeting, for example. Authentication of the user may involve a password, code, credential, key, etc. Authentication techniques are well known and their descriptions are omitted for brevity. The instant message is converted to a TDD message at operation 230, by converting the IM protocol to the TDD protocol, and the TDD message is then transmitted to the user at operation 240.
The user receives the TDD message at the TDD device, and may respond with a TDD message at operation 250. The TDD message sent by the user's device is received and converted to an instant message at operation 260, by converting the TDD protocol to the IM protocol, and is then delivered to the representative at operation 270. In this manner, a two-way conversation may continue between the user and the representative, at operation 280, until the session ends. It is contemplated that timestamps may be used so that messages between the user and the representative do not overlap.
Thus, a user may converse with a representative, or other call recipient, via TDD messages translated to IM messages, using their TDD device or a properly-equipped computing device. Because there is no need for a third party translator, time and expense are saved, and the user's information will be more secure and private.
Alternatively, TDD messages may be converted to IM messages and then to speech that is provided to the representative, and/or the representative may speak in response, and this speech is converted to IM, which is then converted to TDD messages and provided to the user. FIG. 3 is a block diagram of another implementation of a system that provides instant messaging between a TDD user and a recipient of a call from the TDD user, where the IM is converted to speech prior to delivery to the representative, and the representative's speech is converted to IM. FIG. 3 contains elements similar to those described above with respect to FIG. 1. These elements are labeled identically and their description is omitted for brevity.
In the implementation shown in FIG. 3, the entity further comprises a text-to-speech/speech-to-text converter 24. The converter 24 may convert the instant message, which was generated based on the TDD message, to speech that is then provided to the representative. The converter 24 may also convert the representative's speech to an instant message, which may then be converted to a TDD message that is provided to the user. In this manner, the representative may speak and listen as if conversing with a hearing user, and does not have to prepare instant messages. This provides further efficiencies, as the representative does not have to type or read IM text. The converter 24 may contain a well-known text-to-speech converter and a well-known speech-to-text converter, where the text that is being converted to and from may be IM. The text-to-speech converter and the speech-to-text converter may be separate components, modules, or applications, for example.
FIG. 4 is an operational flow of another implementation of a method that provides instant messaging between a TDD user and a recipient of a call from the TDD user. The implementation of FIG. 4 may be similar to that described above with respect to FIG. 2, and includes the conversion of IM text to speech that may be delivered to the recipient of the call, and conversion of the recipient's speech to IM text, which may then be converted to a TDD message that is provided to the user. In an implementation, the recipient may be a representative of an entity, such as a financial services company or a bank, for example.
At operation 400, a user places a call through a TDD device to the entity. A representative associated with the entity may be notified that the incoming call is from a TDD device, at operation 410, similar to operation 210. Alternatively, the representative does not receive such notification, and the call comes to the representative as if the call were from a conventional phone as opposed to a TDD device.
At operation 420, the representative responds to or answers the call with speech (as opposed to typing an instant message as in the implementation of FIG. 2), which is then converted to an instant message. As with FIG. 2's implementation, the representative may request authentication information from the user, such as a password, code, credential, key, etc. The instant message is converted to a TDD message at operation 430, by converting the IM protocol to the TDD protocol, and the TDD message is then transmitted to the user at operation 440. In an alternative implementation, the representative's speech may be converted to a TDD message without the speech being converted to an instant message.
The user receives the TDD message at the TDD device, and may respond with a TDD message, at operation 450. The TDD message sent by the user's device is received and converted to an instant message at operation 460, by converting the TDD protocol to the IM protocol. The instant message is then converted to speech, at operation 470, and is delivered to the representative. In an alternative implementation, the user's TDD message may be converted to speech without the TDD message being converted to an instant message. In this manner, a two-way conversation may continue between the user and the representative, at operation 480, until the session ends.
Thus, as with the implementation of FIG. 2, a user may converse with a call recipient, via TDD messages translated to IM messages, using their TDD device or a properly equipped computing device. Because the call recipient may interact with the user by speech, as in a phone call with a hearing user, the call recipient's efficiency and accuracy may be increased, thereby saving time and expense.
FIG. 5 is a block diagram of an implementation of a converter that may be used to convert one type of message to another, such as TDD messages to IM messages, or IM messages to TDD messages. TDD has well defined protocols and there are many different TDD protocols. One protocol used by TDDs is the Baudot code implemented asynchronously at either 45.5 or 50 baud, 1 start bit, 5 data bits, and 1.5 stop bits. Other protocols that may be used for TDD are dual-tone multi-frequency (DTMF), V.23, etc. V.18 is a dual standard, as it is both an umbrella protocol that allows recognition and interoperability of some of the most commonly used TDD protocols, as well as offering a native V.18 mode, which is an American Standard Code For Information Interchange (ASCII) full- or half-duplex modulation method. Computers can, with appropriate software and modem, emulate a V.18 TDD or other TDD, for example. Some voice modems, coupled with appropriate software, can be converted to TDD modems by using a software-based decoder for TDD tones.
The TDD protocols are translated to a known instant messaging protocol, such as Windows messaging, I Seek You (ICQ), Internet Relay Chat (IRC), etc. For example, IRC is a form of real-time Internet chat or synchronous conferencing. It may be used for group (many-to-many) communication in discussion forums called channels, and it also allows one-to-one communication and data transfers via private messages. IRC is an open protocol that uses transmission control protocol (TCP) and also may use secure sockets layer (SSL). TCP is a protocol developed for the Internet to get data from one network device to another, and SSL is a security protocol for transactions on the Internet, that uses public-key cryptography to provide server authentication, data encryption, and data integrity.
A text remover 500 strips the text and other information (e.g., identifier, header, etc.) from the message. A protocol converter 510 converts the stripped text to the desired protocol, such as IRC, and a message packager 520 packages the converted text into an appropriate package for delivery, e.g., via an Internet chat system.
FIG. 6 is an operational flow of an implementation of a TDD to instant messaging method involving conversion of a TDD message to an IM message. The TDD message is received at operation 600, and the text and other information are stripped from it at operation 610. The text is put into IM format and properly packaged at operation 620, and a channel for delivery to the call recipient is created at operation 630, and may involve routing information, for example. The IM formatted message is then transmitted to the call recipient at operation 640.
FIG. 7 is an operational flow of an implementation of an IM to TDD messaging method involving conversion of an IM message to a TDD message. The IM message is received at operation 700, and the text and other information are stripped from it at operation 710. The text is put into TDD format and properly packaged at operation 720, and a channel for delivery to the TDD user is created at operation 730. The TDD formatted message is then transmitted to the TDD user at operation 740.
It is contemplated that the call recipient may be a person or an automated system involving computers, phones, or both. It is also contemplated that the call recipient described herein may initiate the call (e.g., the representative of the entity initiates the call). In such an implementation, the representative's call may be initiated as an IM, or speech converted to IM, and then converted to a TDD message and delivered to the user who would be the call recipient.
Exemplary Computing Arrangement
FIG. 8 shows an exemplary computing environment in which example embodiments and aspects may be implemented. The computing system environment is only one example of a suitable computing environment and is not intended to suggest any limitation as to the scope of use or functionality.
