Description

MULTILINGUAL TELECOMMUNICATION METHOD AND DEVICE
The present invention relates to a multilingual telecommunication method and device.

 The technical field of the invention is that of telecommunications.

 The invention relates more particularly to a method and a device for remote dialogue between a user of a call terminal, located along a road or a highway, and which is connected by a communication network. at a call centralizing station where a controller or operator receives calls from users, for example following an accident on the road or highway on which terminals are connected to the network.

Such an emergency call installation is for example described in patent application FR 2610467 (SOCIETE DES AUTOROUTES
RHONE-ALPS).

 This document describes a network of emergency call terminals distributed along the track and connected to a central station by means of two pairs of wires common to all the terminals, each terminal being connected in parallel to the two pairs of wires. ; each terminal comprises an electronic circuit capable of transmitting a code on a first pair of wires towards the control station and also capable of recognizing a code when it is transmitted on the same pair of wires by the control station; recognition of this code by the terminal circuit leads to the entry into service of the terminal's voice circuit with connection of the latter to the second pair of wires in the network.

 The invention relates to an improvement made to telecommunications networks, intended in particular for emergency calls by users using terminals located along a road or motorway network.

 The object of the present invention is to provide a method and a device for telecommunication on such networks between such terminals and such a call centralizing station, which allow dialogue in several languages; the invention aims to provide a telecommunication system which allows a dialogue between an operator (located at the call centralizing station) who has a very limited knowledge of foreign languages (which are not his native language or the official language of his country ), and users (who may be foreigners) who do not know the (native) language used by the operator.

 If the user using a terminal of such an emergency call network does not know the language of the country or the language spoken by the operator, it is still necessary to allow a certain dialogue between the operator and user, so that the operator can, in particular, initiate rescue operations, for example by calling on rescue services for the injured if necessary.

 The present invention aims to remedy this gap in existing telecommunications systems for use by users of road and motorway networks.

 Figure 2 illustrates a detail of embodiment according to a preferred embodiment of the invention, of a signal processing device incorporated in the central unit of a call centralizing station.

 With reference to FIG. 1, a remote communication system to which the invention applies comprises, in a manner known per se, a plurality of terminals 1 connected via a network 3 to a call centralizing station 2 .

 The network 3 can be, for example, as in the patent application FR 2610467 mentioned above, a four-wire network or even in particular a network using only one pair of wires.

 Each of the terminals 1 includes a loudspeaker 4 capable of broadcasting to the user sounds representative of a spoken message spoken in a foreign language when the signal delivered to the terminal by the network is generated by the voice synthesis means. used in accordance with the invention or pronounced in the language of the operator when the signal delivered by the network results from a signal delivered by a microphone 7 and corresponding to the words spoken by the operator using a handset 22; the terminal also includes a microphone 5 picking up the words spoken by the user and producing a signal which is delivered / broadcast to the operator for example by a loudspeaker 6 integrated in said handset 22 connected to the central unit 10 of the call central station 2.

 Each of said terminals may further comprise a push button 8 which, when activated, causes the emission, by the corresponding terminal, of a signal on said network 3 allowing said central unit 10 of the call centralizing station 2 , to detect a call and to know the corresponding call terminal.

 Each of the terminals 1 is of course provided with electronic means known to those skilled in the art, for example in the case of the use of a four-wire network, such as those described in the patent application FR 2610467 mentioned above.

 Said call centralizing station 2 essentially comprises a central unit 10 grouping together telephone connection means of known type, preferably under the control of a microprocessor system 23, connected to an interface 15, comprising for example a modulator-demodulator , connecting the central unit 10 to said communication network 3.

 Said central unit 10 is connected to a screen 11 capable of displaying messages 12, as well as to a keyboard 9 by which the service operator in the call centralizing station 2 can enter data which will be processed by said microprocessor 23 (operating and / or programmed according to the method of the invention) and possibly stored in an operating memory (not shown) containing an operating program in accordance with the method according to the invention.

 Said central unit 10 is also connected to said handset 22 incorporating a loudspeaker 6 and a microphone 7 and used by the operator of the call center, which handset is connected by an electrical link 16 to said central unit 10.

 According to the invention, the central unit 10 incorporates on the one hand a memory or portion of memory 13 in which are previously recorded a plurality of written interrogative messages capable of being displayed on the screen 11 connected to the central unit 10, and further comprises a memory 14, in which a plurality of spoken interrogative messages are previously recorded; preferably, the memory 14 is divided into several memory portions; in each portion of memory corresponding to a determined foreign language are recorded data representative of several spoken interrogative messages, each spoken message corresponding to the translation of a corresponding written interrogative message recorded in memory 13.

The operation of the device according to the invention is as follows
- when a user presses the button 8 on a terminal 1, the operator located at the call centralizing station 2, is in phonic or telephone communication with the user, via said network 3, from the central unit 10 and said telephone handset 22 connected to central unit 10.

 In the event that the user is a foreigner, i.e. does not speak the first language, i.e. the operator's native language and / or the official language of the country in which the user is located call centralizing station 2, the operator must have a basic knowledge of a reduced number of predetermined foreign languages, for example between three and six predetermined foreign languages, so as to be able to recognize from the first words spoken by the user located opposite the terminal 1 and transmitted to the operator through said microphone 5 in particular, the language spoken by the user.

 The operator then introduces on the keyboard 9 a datum representative of the foreign language which he believed to recognize and / or which he recognized among said predetermined foreign languages (different from the one he speaks).

 The microprocessor 23 of the central unit 10. under the control of an operating program recorded in an operating memory (not shown) of the central unit, then selects the memory portion 14 corresponding to the language detected by the operator and for which he introduced said language choice data to said keyboard.

 Then, successively. under the control of the microprocessor, a first spoken interrogative message (preferably in the form of an alternative question calling only an affirmative or negative answer) is chosen from the list of spoken interrogative messages previously recorded and digitized in said portion of memory 14 corresponding to the selected foreign language, which message is converted into an electrical signal representative of a spoken message, which electrical signal is routed by the network 3 to terminal 1 and is broadcast by the loudspeaker 4 from terminal 1.

 Because the handset 22 and particularly the loudspeaker 6 of the handset 22, for the entire duration of the (telephone) communication between the call centralization station 2 and the terminal 1 used by the user, is listening (connection ) permanent via the network and the station 2 with the microphone 5 of the terminal, when the alternative interrogative message speaks is broadcast by the loudspeaker 4 of terminal 1, this message is heard by the operator located in the call centralization station 2, because this message broadcast by the loudspeaker 4 will be picked up by the microphone 5 of the terminal and routed to the loudspeaker 6 of the handset 22 by the telephone network used.

 Substantially simultaneously with the generation of this signal by the central unit 10 bound for terminal 1 and the broadcasting in response to this signal of the spoken interrogative message, the interrogative message in written form which corresponds in the operator's language to the message spoken interrogation spoken in the predetermined foreign language, and which is recorded in the written message memory 13, is displayed on the screen 11 as illustrated in FIG. 1, under the control of the microprocessor 23 of the central unit 10.

 When the user answers the question asked which has been sent to him by the central unit 10, the answer is broadcast to the operator by in particular the speaker 6 of the handset 22, the operator having to recognize whether is an affirmative or negative response.

 As a function of the recognition carried out by the operator, the latter enters on the keyboard 9 a datum representative of the affirmative or negative response which is detected and recorded by the central unit 10.

 Depending on the answer given to the previous question, the microprocessor 23. under the control of a program residing in a memory of the central unit 10, searches in memory 14 for a following message to be addressed to the user and intended for call for an affirmative or negative response.

 As illustrated in FIG. 2. according to a preferred embodiment of the device according to the invention, the data recorded in the memory 14 of spoken messages, which could have been previously digitized and recorded in said memory, are delivered to the telecommunications network 3 by the intermediary of a digital analog converter 18, which generates an electrical signal 20 representative of the corresponding spoken message, which signal 20 is added to the signal 19 possibly existing and coming from the microphone of the handset (marks 7 and 22 of Figure 1) used by the operator of the call centralizing station.

 The sum of the signals 19 and 20 produced by the adder 17 constitutes an electrical signal 21 and is routed over said network 3 via said interface 15 provided in the central unit 10.

Such a central unit can for example be constructed from a microcomputer integrating an acquisition, digitization and restitution card for sound signals such as for example an electronic card sold under the reference "SOUND
BLASTER "(registered trademark of CREATIVE TECHNOLOGY,
Singapore).
