Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a Braille telephone device for the welfare of the blind, which is capable of recording the contents of a telephone conversation by printing it in Braille.

(Prior Art) Recently, various telephone devices having advanced and convenient service functions have been developed. For example, memo telephones, telephone facsimiles, and the like have been developed, and text and graphic information are communicated via telephone lines, and tape recorders are also used to record the contents of telephone calls.

However, these various functions are intended for normal healthy people, and are extremely inadequate as functions for the welfare of blind people, for example. That is, even if text/graphic information is recorded as communication information in a memo telephone or a telephone facsimile, a blind person cannot see this information. Further, when a tape recorder is used in combination to record the contents of a call, there is a problem in that it takes a lot of time and effort to search the information recording area and reproduce the contents of the call.

(Problems to be solved by the invention) Telephone devices equipped with various functions that have been developed in the past are intended exclusively for use by able-bodied people, and there are problems in using them for welfare purposes for blind people. .

The present invention was made in consideration of these circumstances, and its purpose is to provide a braille telephone device suitable for the welfare of blind people, which allows blind people to easily check the content of their calls as needed. Our goal is to provide the following.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides a telephone device main body equipped with a normal telephone processing function,
A voice recognition device is provided to recognize at least the transmitting signal or the receiving signal, and the voice-recognized transmitting signal or the receiving signal is converted into Braille and printed out.

(Function) According to the present invention, for example, under a selection instruction of a processing function of the telephone device main body, a sending signal or a receiving signal transmitted through the telephone device main body is voice recognized. and audio H
The H character code string is converted into a Braille code string, and Braille characters made of predetermined irregularities are imprinted (printed) on recording paper.

However, by preserving the recording paper with Braille inscriptions, it becomes possible to effectively use it to check call records by blind people, and it is possible to provide a very useful function for the welfare of blind people. Become.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing a schematic configuration of an embodiment device, and FIG. 2 is a diagram showing an external configuration of the same device.

This telephone device is equipped with normal telephone communication functions and various service functions that have been proposed in the past. It is configured with a function to print and output information in Braille.

In FIG. 2, reference numeral 1 denotes a telephone main body, and on the upper surface of the telephone main body 1, a numeral bar 121, function selection keys 32, and Braille control keys 4 are provided. Further, 5 is a handset, and 6 is a recording paper on which Braille is printed and output.

The various service functions, voice recognition function, and Braille output function described above are provided inside the telephone main body 1, respectively.

However, in FIG. 1, the telephone line has 21114I!
Audio input unit 12 and audio output unit 1 via conversion unit 11
3 are connected respectively. The transmitted voice signal inputted through the transmitter (microphone) 14 of the handset 5 is transmitted from the voice output unit 13 to 2I! The signal is transmitted to the telephone line via the 4-wire converter 11. Further, the received voice signal received by the voice input unit 12 from the telephone line via the 2-wire/4-wire conversion unit 11 is transmitted to the receiver unit (speaker) 15 of the handset 5.
Audio is output through. Transmitting section 10 of this handset 5
A conversation is made between the telephone of the other party and the other party's telephone through the telephone receiver 15.

The control unit 16 also controls various operations (
The control information is inputted via a key manual section 17 consisting of the number pad 29, function selection keys 31, braille control keys 4, etc.

The control information inputted via the key input unit 17 also includes telephone number information and the like when making a telephone call.

Further, control information given from a telephone device of the other party connected via the telephone line is also input to the control section 16 via the voice input section 12. That is, the voice input section 12 has a function of determining whether the received information is voice information or control information, and if it is control information, the received input control information is sent to the control section 16. It has become something to give.

Control 53 of the control unit 16 that inputs control information in this way
Under the D function, the various telephone service functions described above and the braille output function of the call content, which is a feature of this device, are activated.

Now, the braille output function basically consists of a voice recognition section 211, a braille conversion section 22, and so on, as shown in FIG. The Braille printing output section 23 is composed of three blocks.

This Braille output function is activated, for example, when the key human power unit 17 instructs to output a transmission signal in Braille or a reception signal in Braille. According to this instruction, the audio input section 12 receives a transmission audio signal that is input via the transmission section 14 and transmitted and outputted via the audio output section 13, or is received via the audio input section 12 and transmitted to the reception section. 15, a received voice signal outputted as voice is input, and this is voice recognized.

This speech recognition processing is performed by using, for example, continuous speech recognition processing technology for unspecified speakers, which has been proposed in various ways in the past.

Note that this voice recognition may be performed for each of the transmitted voice signal and the received voice signal. In this case, if the recognition processing for each voice signal is performed in parallel using two sets of recognition devices, each voice signal can be can be recognized effectively.

Information about the transmitted voice signal or the received voice signal that has been subjected to voice recognition processing is output as, for example, a character code string. The Braille converter 22 converts each character code into a corresponding Braille code, and the Braille print output unit 23 prints out the code on a predetermined recording paper.

Note that the voice recognition result may be temporarily stored in a character code string buffer, and the character code string may be read out from this character code string buffer and output in braille printout as necessary.

That is, as shown in FIG. 3, the input audio signal is first subjected to speech recognition processing (step a). Then, the character code string obtained as the recognition result is stored and saved in a buffer (step b). Then, the Braille code for the character code stored in the buffer is determined by searching a Braille table (step C), and the Braille code string thus determined is output to the Braille print output section (step d). Braille unevenness is then stamped and printed in order on a predetermined recording paper according to the Braille code string, and the recording paper with the Braille printed thereon is output (step e).

In this way, it becomes possible to record and output the above-mentioned call voice information in Braille, without being affected by differences in the input speed of voice signals, the processing speed of voice recognition, and the printing output speed of Braille.

Incidentally, when recording this braille, attribute information may be added to identify whether the information indicates transmitting voice information or receiving voice information. At the same time, time information of the call may be recorded as attribute information. By using such attribute information, it becomes possible to easily organize information recorded in Braille.

According to this telephone device, which is equipped with the ability to output call audio signals in Braille print, it is possible to record outgoing and received audio signals as Braille information, so it can be used to record a large amount of call information for blind people. It is highly effective and can greatly contribute to the welfare of the blind. Furthermore, by using this braille recording function of the transmitted voice signal, it is also possible to input, for example, memo information of the telephone device user by voice and record it in braille. Furthermore, it is possible to output the communication information in Braille to the communication partner through the telephone, which can bring about great practical effects.

Note that the present invention is not limited to the embodiments described above. Here, the transmitting voice signal or the receiving voice signal is selectively voice recognized, and the recognition result is printed out as Braille. Depending on the situation, only one of them may be output in braille. Furthermore, as shown in Fig. 4, the transmitting voice signal and the receiving voice signal are each stored as voice data in a data buffer, and as necessary, the voice data is read out, voice recognized, and converted into Braille. You may also output it. It goes without saying that the Braille print recording method (print format) is not particularly limited either. In addition, the present invention can be implemented with various modifications without departing from the gist thereof.

[Effects of the Invention] As explained above, according to the present invention, it is possible to voice-recognize the contents of a call made through an N-talk device, and record and output the II result by printing it in Braille. It can bring about great practical effects, such as being able to make a significant contribution to the future.
