JPH0321472A - Telephone for visually or auditorily handicapped person - Google Patents

Abstract

PURPOSE:To enable a handicapped person to understand a telephone communication from a normal telephone using an exclusive telephone as a receiver by a method wherein a transmitted audio signal is outputted as characters for an auditorily handicapped person or as voice and braille for a visually handicapped person. CONSTITUTION:A voice transmitted from a normal telephone 2 is received by an audio input part 3 and converted to an audio electric signal. In an audio signal identification part 4 in which the correspondence with previously registered special characters, such as fillet character or braille character, is stored and learned, an inputted audio pattern is converted to a corresponding character electric signal. In a memory part 5, these audio and character signals are stored, as necessary. An output form selection key 6 is operated. When a braille is selected as an output form, the character electric signal is converted to a braille stamping signal in a processing part 7 for forming projections. A voice is outputted from a speaker 8. In a fillet character printing, a white or black electric signal is converted to a stamping signal and outputted to a fillet character printer 9, wherein fillet characters are successively printed on paper. The braille can be easily stamped by a braille printer 10 on a braille stamping signal converted in the processing part 7.

Description

[Detailed Description of the Invention] Industrial Field of Use This is to provide a telephone set for the hearing-impaired that outputs received content in audio and braille for the visually-impaired and in sumiji for the hearing-impaired. Telephones convert voice into electrical signals and transmit them, and convert the received electrical signals back into voice. The received electrical signal is converted into a magnetic signal and recorded on a magnetic tape.When the received content is reproduced, the recorded magnetic signal is converted into an electrical signal, and the electrical signal is converted back into audio.

Conventional fax machine: By scanning the printed characters and figures with a line sensor, it is identified as a white or black electrical signal and sent sequentially.The receiving side converts the white or black electrical signal into an engraved signal. It is output to a dot printer or laser printer and printed on paper sequentially.As shown in Figure 2 (a) and (b), it is a combination of the presence and absence of protrusions in 6 places in 3 columns vertically and 2 rows horizontally. Represents one letter or number.This protrusion is straight Problems that the invention attempts to solve by using a "Kani type" system that allows simultaneous operation of telephones.General telephones allow visually impaired people to receive audio in the form of audio output, whereas hearing impaired people cannot. Therefore, faxes are the only means of communication for hearing-impaired people.However, faxes require specialized equipment that is compatible with both the sender and the receiver; The only way to do this is to record the voice, and the recorded voice must be transcribed as Braille on special paper using a Braille board or a "crab type". A telephone set for the hearing- and visual-impaired persons of the present invention (a) which receives transmitted voice and converts it into an audio electrical signal; Memorize the correspondence with letters The audio signal recognition unit that is being trained converts the input audio electrical signals into corresponding character electrical signals.Furthermore, the character electrical signals are converted into Braille marking signals.
Saves text/Braille engraving signals Depending on the output format, audio output is possible.
Braille printing is effective for the hearing-impaired, and visually impaired people can understand telephone communications from regular telephones by outputting them in audio and Braille.They can also record the received content and read it back later. Embodiments Below, embodiments of the present invention will be described with reference to the drawings. A voice input processing device currently being developed as a computer input device is used as a telephone for people with disabilities.The voice input section 3 receives voice transmitted from a public telephone or home telephone 2, and converts it into a voice electrical signal. Convert it to this {
Extract a voice section with periodicity unique to voice from a signal that is a mixture of command voice and noise. The extracted audio is analyzed for a certain frequency spectrum, noise is removed, and a repaired audio pattern is extracted. Next, the speech signal recognition unit 4 memorizes and learns the correspondence with special characters such as sumiji and braille that have been registered in advance. Convert to signal.

Next, these audio and text signals are stored in the recording section 5 as needed. Although magnetic tape is generally used to store audio, magnetic disks and semiconductor devices are used depending on the signal storage capacity and processing ability. card,
You can also use a recording device such as an IC card (~ Next, operate the output format selection key 6 to output audio according to the format. One character or number is displayed by combining the presence and absence of protrusions at six locations in two rows. Therefore, when braille is used as an output form, in order to form these protrusions on C, character electricity is generated in the processing unit 7. The signal is converted into a Braille stamp signal.The voice is output from Subica 8, similar to a regular telephone. It is relatively easy to print sumo braille by outputting it to the sumiji printer 9 and printing it sequentially on paper.The braille stamping signal converted by the processing unit 7 allows the dots to be printed at very wide dot intervals, similar to a type of dot printer with large dots. Effects of the Invention As explained above, the present invention is capable of outputting transmitted audio signals in the form of letters for hearing-impaired persons, and in audio and braille for visually-impaired persons. , it is possible to understand telephone communications from regular telephones.Furthermore, the received contents can be recorded and read back later, and there is no need for a dedicated transmitter like a conventional fax machine, making it possible for people with disabilities to read It is possible to understand telephone communications from a regular telephone simply by using the invented dedicated telephone as a receiver, and furthermore, by selecting the output format, it is also possible to transmit messages received by a normal person to a person with hearing impairment.
