STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENTNot applicable.
BACKGROUND OF THE INVENTIONThe present invention relates to the general field of telephone communications. In more particular, the invention relates to systems to assist telephone communications by those persons who are deaf, hard of hearing, or otherwise have impaired hearing capability.
Most modern human communications in both social and business environments takes place through sound communications. Yet within modern society there are many persons who have attenuated hearing capability. To assist those persons in making use of our telephonic communication system built for the hearing majority, there has been developed a system of telephone communication which has been principally used by the deaf community. That system makes use of a category of device known variously as a telecommunication device for the deaf (TDD), text telephone (TT) or teletype (TTY). Current TDDs are electronic devices consisting of a key board and a display as well as a specific type of modem, to acoustically or directly couple to the telephone line. Modern TDDs permit the user to type characters into their keyboard, with the character strings then encoded and transmitted over the telephone line to be displayed on the display of a communicating or remote TDD device.
Most TDD communication is conducted in an idiosyncratic code specific to the community of TDD users. This code, known as Baudot, evolved historically at a time when many telecommunication devices for the deaf were based on mechanical or electromechanical devices rather than the current technology based on digital electronic components. Accordingly, the Baudot protocol was constructed for a set of constraints which are no longer relevant to present date devices. The original Baudot protocol was a unidirectional or simplex system of communication conducted at 45.5 Baud. The conventional Baudot character set was a character set consisting of 5 bit characters and the system encodes the bits of those characters in a two-tonal system based on carrier tones of 1400 and 1800 Hertz.
The system of TDD communications is widely used and in fact has become indispensable to the deaf community throughout the industrialized world. Deaf persons extensively communicate with their neighbors and with other deaf and hearing people remotely, using the TDD system. In addition, systems have been developed to facilitate the exchange of communication between the deaf community and hearing users who do not have access to or utilize a TDD device. In the United States, telephone companies have set up a service referred to as a “relay.” A relay, as the term is used herein, refers to a system of voice to TDD communication in which an operator, referred to as a “call assistant,” serves as a human intermediary between a hearing user and a deaf person. Normally the call assistant wears a headset that communicates by voice with the hearing user and also has access to a TDD device which can communicate to the deaf user using a TDD appropriate protocol. In normal relay operations in the prior art, the call assistant types at a TDD keyboard the words which are voiced to her by the hearing user and then voices to the hearing user the words that the call assistant sees upon the display of his or her TDD. The call assistant serves, in essence, as an interpreting intermediary between the deaf person and the hearing person to translate from voice to digital electronic forms of communication.
A system to assist users of the telephone system who are hard of hearing but not deaf has been described. This system, sometimes referred to as text enhanced telephony, makes use of the existence of relays to supplement telephone communications for users who can hear, but have attenuated hearing capabilities. This systems includes, in its simplest embodiment, a visually readable display connected in series between the telephone used by the assisted user and the connection to the telephone network. The text enhanced telephone call is connected through a relay which transmits both the voice of the hearing user at the other end and a text stream of the words spoken by that user on the same telephone line. The details of the concept and of some embodiments of that system are disclosed in U.S. Pat. No. 6,075,842, the disclosure of which is hereby incorporated by reference.
BRIEF SUMMARY OF THE INVENTIONThe present invention is summarized in that a relay system to facilitate the translation of information and communication between deaf and hearing persons includes a call assistant who re-voices the words of the hearing person which are spoken to the call assistant. The words spoken by the call assistant are recognized by a speech recognition computer program which has been trained to the voice pattern of the call assistant, such that the words are promptly translated into a high speed digital communication protocol. That high speed digital communication message is then transmitted electronically promptly by telephone to a visual display accessible to the deaf person.
It is an advantage of the invention described herein that the call assistant does not have to type most, if any, of the words spoken by the hearing person in the communication session so that the overall speed of communications from the hearing person to the deaf person is dramatically increased.
It is an object of the present invention that the design and utilization of a relay operated in accordance with the protocols described herein permits the introduction of small hand-held personal interpreter which will enable on the spot communications between deaf persons and hearing persons wherever the deaf persons might go.
Other objects, advantages and features of the present invention will become apparent from the following specification when taken in conjunction with the accompanying drawings.
The present invention is intended to provide an alternative arrangement for the delivery of text assisted telephone services, also called captioned telephone, to a telephone system user with diminished hearing. The present system is intended to take advantage of two developments in the field of assisted telephone services, the personal interpreter and the re-voicing relay. The arrangement for using these capabilities here is designed not to provide text services for the profoundly deaf, but to provide a text assistance service for those who can hear, but who may have diminished hearing. This service is designed to supplement rather than replace the transmission of the spoken voice word to the assisted user. To assist understanding what is contemplated here, the basic technologies of the personal interpreter and the re-voicing relay will be described here first, after which the description will return to the main topic, text assisted telephone services or, as they are also known, captioned telephone services.
The personal interpreter is intended to be a small portable device capable of delivering, with the support of a relay, text to a deaf user of any human conversation occurring in the presence of the personal interpreter. The personal interpreter is set up to connect telephonically to a relay, transmit spoken words to the relay, and then display for the assisted user the text of the words transmitted over the telephone connection to the relay. To make the personal interpreter work more seamlessly to produce more conversation-like communication, a faster relay methodology was needed. To fill this need, the re-voicing relay was designed.
The re-voicing relay is based upon the underlying technology of using voice recognition software, operated by a call assistant (a “CA”), to assist in the voice to text translation inherent in providing relay services. The re-voicing strategy is described in U.S. Pat. No. 5,909,482, the disclosure of which is hereby incorporated by reference. The re-voicing relay has its first implementation in providing voice to text transcription services for the deaf. However, the relay voice to text transcription service has use for users other than those who are deaf. It is envisioned that there are a number of hearing or partially hearing users who would have reason to benefit from voice to text transcription services. Relay voice to text service might also be useful for any application in which it is desired to supplement voice communications by a text transcription of the voice spoken on the telephone. Thus, while the operation of the relay will sometimes be described here by referring to an “assisted user,” who may be deaf or hard of hearing, but who also may be a normally hearing person who simply wants text assistance for some reason. The user at the other end of the line will be referred to here as the hearing user, simply for the purpose of having something to call that person, even though both users may be hearing.
Personal Interpreter.

A brief description of the operation and functionality of the personal interpreter reveals the dramatic improvement and convenience and portability that this device gives to text assisted people. A assisted user could go into an establishment, be it a government office or retail facility, in which there are only hearing persons. The assisted person would carry with him or her the personal interpreter 10. The assisted user would then place the personal interpreter 10 upon a counter or other surface, open it up, and press the initiation key or start button. The microprocessor 16 and modem 18 of the personal interpreter then power up and act in many ways like a normal TDD device operating in telecommunication standard, such as Turbo code. However, there is one critical difference. The start or initiation key further causes the microprocessor 16 of the personal interpreter to dial a relay to set up a relay communication session and includes in its communication with the relay a message, using the enhanced command features available in advanced telecommunication protocols, such as Turbo Code, to initiate a special format of relay call adapted for the personal interpreter. Other codes which permit command functions, such as ASCII or CCITT, could also be used. The first operation is to activate the cellular telephone and direct the cellular telephone to dial the number of a relay operating in accordance with the method of the present invention. The cellular telephone dials the relay. Obviously, no wired connection is required to allow the cellular telephone function to establish a telephone connection with the remote relay, but alternatively the jack 28 to a conventional telephone line could be used. In addition, when the relay answers the telephone connection, the microprocessor 16 of the personal interpreter 10 is instructed to provide command codes to the remote relay. These command codes, a feature possible through the use of Turbo Code, permits the personal interpreter to tell the relay that this is a personal interpreter-type relay communication session. All of this can happen in the time necessary to initiate the cellular call, perhaps two to ten seconds.
Then, the assisted person can use the personal interpreter to translate words spoken by hearing persons in the presence of the personal interpreter into visually readable text. This is done by the personal interpreter 10 through an unseen relay. Words spoken by the hearing persons in the presence of the personal interpreter 10 are picked up by the microphone 22. Those words are then transmitted through the cellular telephone 20 to the remote relay. The relay, operating as will be described below, then immediately transmits back, in enhanced Turbo Code, a digital communication stream translating the words that were just spoken. The words are received by the modem 18, and the microprocessor 16 in the personal interpreter 10, and it is displayed promptly upon the display screen 14. If the assisted person can speak, he or she may then answer the hearing person with a spoken voice, or, the assisted person may alternatively type upon the keyboard 12. If the assisted user types on the keyboard 12, the personal interpreter transmits the communication by digital communication to the relay. The call assistant at the relay then reads and speaks the words typed by the assisted user which are transmitted to the speaker 22 contained in the personal interpreter into a voice communication which can be understood by the hearing users. The filter 26 filters out the digital communication frequencies from the sound generated by the speaker 22. Thus, in essence, the assisted person has a personal interpreter available to him or her at all times of the day or night wherever the assisted person is within the range of the cellular telephone system. Also, because the relay is preferably operating in accordance with the fast translation methodology described below, a very conversation-like feel can occur in the communication session between the assisted user and the hearing persons in the presence of the personal interpreter 10. In order for this communication session to be satisfactory to the hearing users as well as the assisted person, however, the relay must operate exceedingly rapidly. It is, in part, to meet the need for the exceeding rapidity of this conversational style of communication that the re-voicing relay protocol has been designed.

Captioned Telephone.
As mentioned earlier, captioned telephone is a technology intended to provide text assistance to assisted user during the course of a voice telephone communication session. As will become apparent from the discussion below, a captioned telephone connection can be a single line connection or a multiple line connection. There are advantages and disadvantages of each approach. A single line connection is known in the art, as exemplified by U.S. Pat. No. 6,075,842, mentioned previously. The advantages and details of the use of a multiple line connection are described below. The discussion of captioned telephone will begin with a single line connection.
Shown in
The two line captioned telephone is indicated in
The main advantage of the two-line approach to captioned telephone is that the captioned telephone service can be added to a telephone call already in progress. By contrast, to use single line captioned telephone for an incoming call, the call must be directed through the relay to the assisted user at the beginning of the call. For a two-line captioned telephone call, however, the call can be started as a normal telephone communication session, without the relay or the captioning. Then, if the assisted user decides captioning would be helpful to his or her understanding of the conversation, the captioning service can be added while the call is in progress. To add the captioning service, the assisted user simply has the PICT device dial the relay over the second telephone line. The voice of the hearing user is then transmitted over the second telephone line to the relay. The relay converts the voice to text and the text stream created by the relay returns to the assisted user, also over the second telephone line. Note that in this arrangement, as indicated in
One device intended to implement the two-line captioned telephone approach is illustrated in
This example assumes that the digital carrier signals for the text message are carried on high frequencies, and the low pass and high pass filters are used to separate voice from text. While this filtering can be implemented as an analog filter, in many telephonic systems today, digital forms of communication are used. Using a digital communication protocol between the relay and the PICT device, communication is in the form of digital data packets of either text or digitized voice. In that event, the logical filtering simply consists of not creating any acoustic noise from the packets designated as carrying text.
Several physical versions of the PICT device are contemplated. In the version illustrated in
It is a desirable feature of the two-line captioned telephone arrangement that the use of the captioning service is transparent to the hearing user. The hearing user would dial to connect to the assisted user as with any other telephone user. The assisted user invokes the captioned telephone service without the need to involve the hearing user at all. The service can be used equally well and transparently for both incoming and outgoing calls.
It is also envisioned that the captioned telephone service can be implemented in a way that uses three telephone lines. One line is for voice communications with the hearing user. The second line is directly connected to the first line so that the voice of the hearing user is transmitted to the relay. The third line is a connection to transmit the text stream from the relay to the station of the assisted user.
In the implementation of a relay providing captioned telephone service, the relay receives the voice of the hearing user and transmits both a digital text message stream and the voice of the hearing user over a telephone connection to the station of the assisted user. It is to be understood, however, that a conventional telephone single line connection is only one example of a telephonic connection that can be used in this arrangement. Digital wireless connection, or PCS connection, or even internet protocol (IP), wired or wireless connection can be used to connect the relay to the assisted user, so long as the connection in capable of transmitting voice to that user.
Thus the term telephone line as used in this specification is intended not only to apply to a traditional land-line two-wire telephone line, but also to all equivalents that offer similar functionality. Each of the telephone lines could be, for example, a portion of the bandwidth of an ISDN or DSL service. The telephone line could be an analog or digital cellular telephone link or a PCS connection. The PICT device could also be connected to the internet communication in IP, and in that event the two telephone lines would simply be simultaneous digital data exchange with two remote locations.
It is to be understood that the present invention is not limited to the particular illustrations and embodiments disclosed above, but embraces all such modified forms thereof as come within the scope of the following claims.
