Abstract

A relay is described to facilitate communication through the telephone system between deaf people and hearing people. To overcome the speed limitations inherent in typing, the call assistant at the relay does not type most words but, instead, re-voices the words spoken by the hearing person into a computer operating a voice recognition software package trained to the voice of that call assistant. The conversation-type flow of communications achieved by this type of relay enables the design of a new class of interpreters for the deaf.

Claims

1. A method of operating a relay system using a call assistant to facilitate communication between a deaf person and a hearing person by telephone comprising the steps of

transmitting the voice of the hearing person when speaking to the ear of the call assistant;

the call assistant speaking in voice the same words that the call assistant hears spoken by the hearing person into a microphone connected to a digital computer;

the digital computer using voice recognition computer software trained to the voice of the call assistant to translate the words of the voice spoken by the call assistant into a digital text message stream containing the words spoken by the call assistant;

transmitting the digital text message stream created by the computer by telephone connection to a telecommunication device within sight of the deaf person; and

the telecommunication device displaying in visually readable text the words in the digital text message stream.

2. A method as claimed in claim 1 further comprising the step of using the voice spoken by the call assistant to create a noise canceling signal also transmitted to the earphone of the call assistant so that the call assistant hears less of his or her own spoken voice.

3. A method as claimed in claim 1 further comprising a switch to switch the relay between one mode in which the voice of the call assistant is transmitted to the computer and another mode in which the voice of the call assistant is not transmitted to the computer but is instead transmitted over the telephone system to the hearing person.

4. A method as claimed in claim 1 further comprising the step of buffering the voice of the hearing person between the telephone system and the earphone of the call assistant selectively under the control of the call assistant.

5. A method as claimed in claim 1 wherein there are separate telephone lines of the telephone system used for communicate between the call assistant and the hearing person and the call assistant and the deaf person.

6. A method as claimed in claim 1 wherein there is a single telephone line of the telephone system used to communication between the call assistant and the hearing person and the call assistant and the deaf person, the digital text message stream and the voice of the hearing person both being transmitted over that single telephone line.

7. A relay to facilitate communication between a deaf person using a telecommunication device for the deaf and a hearing person through a telephone system and using a call assistant, the relay comprising

a speaker connected to receive voice communications from the telephone system and transmit those voice communications to the ear of the call assistant;

a microphone connected to pickup voice spoken by the call assistant;

a digital computer connected to the microphone, the computer programmed to use a voice recognition computer software package trained to the voice of the call assistant to translate the words spoken in voice by the call assistant into a digital text stream;

a modem to transit the digital text stream created by the computer over the telephone system to the telecommunication device for the deaf of the deaf person; and

noise attenuating means responsive to the voice spoken by the call assistant and connected to the speaker to attenuate the noise of the voice of the call assistant from the sounds heard in the ear of the call assistant.

8. A relay as claimed in claim 7 wherein there are separate telephone lines of the telephone system connected between the call assistant and the hearing person and the call assistant and the deaf person.

9. A method as claimed in claim 7 wherein there is a single telephone line of the telephone system used to communicate between the call assistant and the hearing person and the call assistant and the deaf person, the digital text message stream and the voice of the hearing person both being transmitted over that single telephone line.

10. A relay to facilitate communication between a deaf person using a telecommunication device for the deaf and a hearing person through a telephone system, the relay operated by a call assistant, the relay comprising

a speaker connected to receive voice communications from the telephone system and transmit those voice communications to the ear of the call assistant;

a microphone connected to pickup voice spoken by the call assistant;

a digital computer connected to the microphone, the computer programmed to use a voice recognition computer software package trained to the voice of the call assistant to translate the words spoken in voice by the call assistant into a digital text stream;

a modem to transit the digital text stream created by the computer over the telephone system to the telecommunication device for the deaf of the deaf person; and

a switch to alternatively connect the voice of the call assistant to the computer or to the telephone system for transmission to the hearing person.

11. A relay as claimed in claim 10 wherein there are separate telephone lines of the telephone system connected between the call assistant and the hearing person and the call assistant and the deaf person.

12. A method as claimed in claim 10 wherein there is a single telephone line of the telephone system used to communicate between the call assistant and the hearing person and the call assistant and the deaf person, the digital text message stream and the voice of the hearing person both being transmitted over that single telephone line.

13. A relay to facilitate communication between a deaf person using a telecommunication device for the deaf and a hearing person through a telephone system, the relay operated by a call assistant, the relay comprising

a earphone connected to receive voice communications from the telephone system and transmit those voice communications to the ear of the call assistant;

a microphone connected to pickup voice spoken by the call assistant;

a digital computer connected to the microphone, the computer programmed to use a voice recognition computer software package trained to the voice of the call assistant to translate the words spoken in voice by the call assistant into a digital text stream;

a modem to transit the digital text stream created by the computer over the telephone system to the telecommunication device for the deaf of the deaf person; and

a voice buffer connected between the telephone system and the earphone of the call assistant, the voice buffer being controlled by the call assistant, so that the voice assistant can buffer the voice of the hearing user between the telephone system and the ear of the call assistant.

14. A relay as claimed in claim 13 wherein there are separate telephone lines of the telephone system connected between the call assistant and the hearing person and the call assistant and the deaf person.

15. A method as claimed in claim 13 wherein there is a single telephone line of the telephone system used to communicate between the call assistant and the hearing person and the call assistant and the deaf person, the digital text message stream and the voice of the hearing person both being transmitted over that single telephone line.
