text: fig1 shows an embodiment of the pattern processing system specific to a user group according to the invention which provides a public user terminal 10 for user inputs . typical applications of such an embodiment of the invention are the carrying out of bank transactions at an automatic bank counter 10 , calling up of information at the information kiosks 10 mentioned above , or purchasing tickets from an automatic ticket vending machine 10 . the public user terminal 10 has a graphic display 11 , an input keyboard 12 , a microphone 13 for putting in spoken messages of a user , and an insertion slot 14 for a chip card 70 characteristic of the user , for example an ec or customer card . furthermore , it comprises a local speech recognition device 42 which has a local data memory 32 for storing pattern processing data sets specific to a user group for a speech processing specific to the user group . on the user &# 39 ; s chip card 7 , which is inserted into the slot 14 for the purpose of using the system , there is , for example , a chip 71 for storing data typical of the application , for example the account number of the bank account in the case of a bank card , as well as a further chip 72 for storing a unique identifier of the user group of the user as laid down for the speech processing specific to the user group . such a unique identifier may consist , for example , of a number , or alternatively a symbolic name is conceivable , for example the name of a widely known person who also belongs to this user group such that the speech processing characteristic of this person is typical of the user group . such a symbolic name , but also a number can be readily remembered by a user so that such a unique identifier can be transmitted to the pattern processing system also without the help of a chip card , for example through the microphone 13 or the keyboard 12 . in this case , the chip 72 would be redundant on the chip card 70 . alternatively , furthermore , all information could be accommodated on a single chip 71 on the chip card 70 , including any user group characterization . if all pattern processing data sets specific to the user group are stored in the local data memory 32 , the local speech recognition device 42 is capable of operating fully independently locally . such a “ stand alone ” automatic machine is particularly suitable , for example , for the sale of cigarettes or some other articles directly available from vending machines . the public user terminal 10 may alternatively be connected via a network 20 to further data memories 30 . . . 31 for the storage of pattern processing data sets specific to user groups for the purpose of a speech recognition specific to the respective user group . the network 20 may then be , for example , a private man ( metropolitan area network ), for example the network of a bank . the network 20 may alternatively be realized in the form of a public network , in particular the internet . a possible hybrid form is , for example , a vpn ( virtual private network ) realized on the basis of the internet . fig2 shows a further embodiment of the pattern processing system according to the invention which is specific to a user group . as in fig1 , the network 20 and the data memories 30 . . . 31 connected thereto are shown . by contrast to fig1 , however , the speech recognition devices 40 . . . 41 are also connected to the network 20 . the user inputs are made in a public user terminal 10 here , which terminal , unlike fig1 , has no local speech recognition device 42 with a local data memory 32 , or through a telephone 60 or a pc , a laptop , or the like 50 , which are all connected to the network 20 for this purpose or can be connected thereto . these and other input possibilities such as , for example , the public user terminal 10 shown in fig1 with a local speech recognition device may be realized all or only in part in a pattern processing system specific to a user group . the scenarios shown in fig1 and 2 accordingly differ especially in the arrangement of the speech recognition device 42 or 40 . . . 41 in which the recognition of the spoken utterances of a user takes place . the speech recognition device 42 accommodated locally in the public user terminal 10 of fig1 is particularly suitable for the case in which only simple commands are to be recognized and the public user terminal 10 is mainly used by the same customers all the time . a comparatively simple and inexpensive speech recognition device 42 will suffice in this case , and the pattern processing data sets specific to the user group of the main users may be stored in the local data memory 32 of the speech recognition device 42 for a speech recognition which is specific to the user group . further pattern processing data sets specific to the user group , for example required by itinerant users and not present locally in the data memory 32 , are loaded from data memories 30 . . . 31 connected via the network 20 . this leads to a small overall load of the network 20 . in fig2 , the speech recognition of the spoken utterances of a user takes place in the speech recognition devices 40 . . . 41 connected via the network . this is useful in the case of more complicated spoken utterances which require a high recognition performance and / or in the case of continually changing users . the joining together of the speech recognition tasks and the data storage yields advantages in the machine occupancy , the memory space required , and the necessary data traffic through the network 20 . thus it may be useful , for example , to connect the speech recognition devices 40 . . . 41 with one another and with the data memories 30 . . . 31 by means of a broadband sub - network within the network 20 . it may also be advantageous in certain cases to allocate the recognition of the spoken utterances of individual users always to the same speech recognition device 40 . . . 41 as much as possible , which device may then hold the pattern processing data sets specific to the user group of this user in local data memories again . besides the system embodiments mentioned above , many further modifications may be readily implemented by those skilled in the art in dependence on the field of application . it suffices accordingly to mention here the technique of mirrored data storage which is sufficiently known from the field of distributed databases . the data of a user , i . e . a user group in this case , are held in several , usually spatially widely separated data memories , for example in the memories 32 and 30 . . . 31 in fig1 , so as to afford the user a fast access to his / her data also in the case of a high load on the network 20 . the consistency of the data held in the individual memories is then ensured by means of suitable synchronization procedures which are less critical as to time and may be carried out , as desired , at times of low network loading . a further embodiment of the invention arises when the pattern processing data sets specific to user groups are not held in data memories belonging to a system and designed for pattern processing specific to the user groups , but are made available , for example , by a third - party provider or alternatively by a user himself ( for his own user group ). in the former case , third parties may specialize in the creation , management , and / or updating of the pattern processing data sets specific to the user groups in order to make them available to the operators of the pattern processing systems specific to the user groups , for example against payment . third parties may also take care of the definition of the user group membership for the users . in the latter case , a user himself would download the pattern processing data sets specific to his own user group , for example from one of the data memories 32 , 30 . . . 31 of a pattern processing system specific to the user group . if a different pattern processing system specific to user groups is used , which system itself does not have the pattern processing data sets specific to the respective user group of this user , he may make the respective data available to the system on the laptop 50 . in general , however , he may also make them available via a pc connected to the network 20 , i . e . in particular to the internet , in which case he would then inform the system of the address of this pc . in this scenario , accordingly , the message containing the address of the pc or laptop 50 would perform the task of providing the unique identifier of the user group . user terminals used in the embodiments described above for obtaining access to the system were public user terminals 10 of average complexity , telephones 60 , and pcs or laptops 50 , but alternative solutions are equally possible . examples are mobile telephones and information kiosks with complicated multimedia interaction possibilities such as touch screens , cameras , loudspeakers , etc . fig3 is a diagram showing the contents of a data memory 30 for the pattern processing data sets 80 . . . 81 specific to the user groups . the data memory 30 , which here represents the local data memory 32 as well as the further data memories 30 . . . 31 connected to the network 20 , is a known computer data memory , for example a hard disk . the pattern processing data sets 80 . . . 81 specific to user groups may be available in the form of individual data files , for example in binary code suitable for the pattern processing system specific to user groups . an alternative possibility is an organization in the form of a database or the like . fig4 shows a possible sequence of the use of a pattern processing system specific to user groups according to the invention in the form of a flowchart . only those processes are discussed which are relevant to the pattern processing specific to user groups , while actions specific to the application such as , for example , the communication of a bank account number and a pin code for a banking application are not represented . after the start block 101 , the pattern processing system specific to user groups requests a user in process block 102 to identify his user group , i . e . to enter into the system a unique identifier of the user group defined for the respective user for the purpose of a pattern processing specific to the user group . after the decision block 103 , the further process branches off in dependence on whether the user knows his user group or not . if the user knows his own user group , he communicates it to the system in block 104 in that , for example , he inserts the chip card 70 into the insertion slot 14 of a public user terminal 10 , in the scenarios of fig1 and 2 , he uses the keyboard 12 or the microphone 13 of the public user terminal 10 , or he makes the user group known to the system through a telephone 60 or a laptop 50 . the system then searches in block 105 the pattern processing data set specific to the user group of the user in a data memory 32 , 30 31 and makes it available in a pattern processing device 42 , 40 . . . 41 . if the user does not know his own user group , the system requests him in block 106 whether he wants the system to define a user group for him now . if he wants to do so , the system collects training pattern inputs of the user in block 107 and processes these so as to define a user group for the user . the user group thus determined is communicated to the user in block 108 , and the control switches to block 105 described above , in which the pattern processing data set specific to the user group of the current user is looked up in a data memory 32 , 30 . . . 31 and is made available to a pattern processing device 42 , 40 . . . 41 . if the user does not want a user group to be laid down for him now , for example because he has no time for it at the moment or because a user group was assigned to him already , whose unique identifier he does not have available at the moment , the control branches from block 106 to block 109 . there a user - independent pattern processing data set is looked up in a data memory 32 , 30 . . . 31 and is made available to a pattern processing device 42 , 40 . . . 41 such that the subsequent pattern processing steps are carried out independently of the special characteristics of the user . the user - group - specific or user - independent pattern processing data set made available to the pattern processing device 42 , 40 . . . 41 in one of the blocks 105 and 109 may be dependent on further conditions . thus , for example , different ambient conditions may hold for different applications , for example different background noises in the case of speech recognition , or different terminals for user inputs such as the microphone type in the case of speech input or the camera type in the case of gesture recognition , and a suitably adapted pattern processing data set may be used for these . after block 105 or 109 , as applicable , the pattern input of the user is processed in block 110 , i . e . the user is requested to enter a pattern and the pattern entered is recorded and processed . such pattern inputs may be spoken utterances put in through a microphone 13 or a telephone 60 . other possible inputs are handwritten texts and / or pointer actions for selecting menu items offered on the display 11 . the display 11 of the public user terminal 10 may be constructed for this purpose , for example , as a touch screen , and / or the public user terminal 10 could be fitted with a camera . optionally , the pattern inputs of the user effected in block 110 may be put into intermediate storage and may be used , for example , for testing the user group definition for the user . when a sufficient amount of user inputs has been collected for such a test and it has been ascertained that the instantaneous user group definition is not an optimum for the user from the point of view of pattern processing , the system may load a better suited pattern processing data set specific to the user group of the user , in consultation with the user , into a pattern processing device 42 , 40 . . . 41 so as to carry out the further pattern processing steps therewith . such a procedure may also be carried out , for example , if the patterns had been processed up to that moment on the basis of a user - independent pattern processing data set . in block 111 , the actions corresponding to the pattern input of the user are carried out , for example account data are shown on the display 11 of the public user terminal 10 in the case of a bank transaction . it is also possible for return questions to be put to the user . the user may also be requested for a further input such as , for example , a lacking bank code number . it is decided in block 112 whether the interaction with the user has been completed . if this is not the case , the control returns to block 110 so as to process the next pattern input from the user . if the interaction with the user is complete , any new or modified user group is stored in the data memory 32 , 30 . . . 31 for the user , if applicable , if these data had been , for example , held in storage locally only in one of the speech recognition devices 42 , 40 . . . 41 up to that moment . then the system terminates the processing of the user inputs in block 114 . the termination of the interaction with the user in block 112 may follow , for example , the recognition of a positive reply of the user to a relevant previous system question in block 110 . alternatively or additionally , however , a termination button on the input keyboard 12 of the public user terminal 10 may be provided , which may be operated at any moment in the man - machine communication . further modifications obvious to those skilled in the art are conceivable . blocks 107 and 113 provided the possibility of defining a user group for the user during such a man - machine communication , and blocks 110 and 113 rendered it possible to modify such a user group definition . defining or modifying a user group , however , need not take place within the framework of a utilization of the system , for example for carrying out bank transactions , but it may alternatively be done separately . this possibility would appear to be particularly interesting , for example , for one of the scenarios shown in fig2 in which a user can have his user group defined at leisure from his own home he may then , for example , load a software made available by a system operator locally into a laptop 50 and / or use the infrastructure of the operator accessible via the internet such as processors , programs , and / or data memories . the scenario for defining a user group directly at the public user terminal 10 as described with reference to fig4 also has its justification because this definition is better adapted to the conditions of use of the relevant machine such as , for example , microphone or camera properties or ambient noise . although fig4 clarified essential aspects of a method according to the invention for a pattern processing specific to user groups , it will be clear to those skilled in the art that such a method should contain further mechanisms in practice , for example for the treatment of error conditions . thus it may arise , for example , that the user group of a user laid down by a system is not known to another system . this other system may then act for the purpose of error treatment , for example , exactly as in the case described starting from block 106 , where the user does not know his own user group at that particular moment .
