     DETAILED DESCRIPTION OF THE INVENTION 
     The above described drawing figures illustrate an invention utilizing a copier apparatus not unlike common copiers of well known design, broadly used in business and commerce, the invention comprising: a copying machine  10  providing means for storing  20  copier paper  22  such as a cassette tray, means for positioning  30 , such a glass surface, a master document  32  having a master document image to be copied, means for moving  35  such as a conveyor device as is well known in the art, of at least one piece of the copier paper  22  from the storing means  20  to a means for imaging  40 , for establishing a permanent image of the master document image onto the at least one piece of the copier paper  22  so as to produce at least one copy  50  of the master document, such imaging means  40  being any one of the well known techniques such as xerography, thermal imaging, laser printing, jet spray printing, etc., and means for moving  35  the at least one copy to a means for storing  52  of the copies  50 , again the conveyor device; means for storing  60  a plurality of English and other language inventory human voice commands  62  and a plurality of machine voice responses  64 , such as a digital storage device, e.g.: bubble memory or magnetic domain memory; means for receiving  70  each action-request human voice command such as a microphone; means for comparing  80  each said action-request human voice command with each one of the inventory human voice commands  62  in turn until a match is found such as a digital comparitor as is well known in the field of logic circuits; means for selecting  90  each machine voice response such as a computer logic program  100 , from the plurality of machine voice responses  64 , corresponding to each said match; means for generating each audible message  110  corresponding to each selected machine voice response, such as a playback circuit with a loudspeaker; and means for operating, such as a control circuit  120 , the copying machine  10  in response to each action-request human voice command, again a simple logic circuit for activating the various parts of the copier in response to logic circuit function as is well known in the art. 
     The present invention preferably further comprises a means for selecting a human language for operating the copying machine, such as a keyboard  130  for inputting a selected language, or by programmed prompting, i.e., a verbal phrase, in each of several selected foreign languages  66  until a response is received by the copier in one of the languages, and still further comprises a means for correlating each of the action-request human voice commands spoken in a selected non-English language with the plurality of inventory human voice commands. Such a correlating means may be simply a computerized look-up table for cross-referencing all language responses to English as is well known in the art. In accordance with the foregoing the present invention further comprises a means for generating each audible message corresponding to each selected machine voice response in the selected non-English language as may be achieved by a logic program in any common computer system and is preferably a part of the program  100 , i.e. implemented in software. 
     Preferably, the invention further comprises a means for locking-out all human voice commands not preceded by a security code  68  input wherein the locking-out means is a voice print of a users name. The voice print is preferably an optical image of the users name displayed in the frequency domain as produced by a frequency domain translator  140  and input therefrom into an optical reader  150 . Such a voice print and the means for producing it onto a thin-film-transistor matrix or a liquid crystal display device (optical reader  150 ), as are well known, is clearly within the ability of one of skill in the art. By providing a reading device  150  adjacent to the memory and display device  160 , the voice print may be digitized and stored for reference for later comparison with the same utterance by a person seeking to activate the copier  10 . 
     In the case where a voice command is not possible, the invention preferably further comprises a means for manual inputting of commands such as the well known touch sense screen input device  170 . 
     In the case where it is desired to use a document transferred electronically, the invention further comprises a means for receiving, storing and functionally using  180  an electronic or optical reproduction of the master document. Such techniques are well known and in general use the public in copier equipment from, for instance, the Xerox Corporation. 
     The above described invention preferably utilizes a method of operating comprising the steps of: providing a copying machine having a means for storing copier paper, means for positioning a master document having a master document image to be copied, means for moving at least one piece of the copier paper from the storing means to a means for copying, means for establishing a permanent image of the master document image onto the at least one piece of the copier paper so as to produce at least one copy of the master document, and means for moving the at least one copy to a means for storing copies; storing a plurality of English language inventory human voice commands and a plurality of machine voice responses; receiving an action-request human voice command; comparing said action-request human voice command with each one of the inventory human voice commands in turn until a match is found; selecting a machine voice response, from the plurality of machine voice responses, corresponding to said match; generating an audible message corresponding to said selected machine voice response; repeating steps b-f until an action is identified; and then causing the copying machine to carry out said action. The method preferably further comprises the step of selecting a human language for operating the copying machine and still further comprising the step of correlating each of the action-request human voice commands spoken in a selected non-English language with the plurality of inventory human voice commands. The method preferably further comprises the step of generating each audible message corresponding to each selected machine voice response in the selected non-English language. The method preferably further comprises the step of locking-out all human voice commands not preceded by a security code input such as a voice print of a users name as for instance an optical image of the users name displayed in the frequency domain and the locking-out step utilizes an optical comparison method. The present inventive method preferably comprises a step of manually inputting commands when voice is not functional. The method further advantageously comprises the step of receiving, storing and functionally using an electronic or optical reproduction of the master document. 
     The method may be more specifically defined and its benefits understood in light of the following time sequence which is only one possible example, as follows: 
     1. An individual wanting to use the present invention copier physically approaches the copier  10 . 
     2. The copier senses the presence of the individual standing in front of the copier by utilizing an infrared or similar sensor  72 . 
     3. The copier immediately produces an audible phrase; “I am ready. What is your code?,” illuminates a blinking “ready” lamp  74  on the front panel of the copier and starts a response waiting timer  76 . 
     4. If no response is received, before the response waiting timer cycles, the copier shuts down its ready lamp and moves into a standby mode maintaining only its IR detector circuit in the “on” state. 
     5. If the individual replies with an audible code statement, usually the individual&#39;s actual name or a special code name assigned to that individual, and the statement is intelligible to the copier after searching for a match in inventory, the copier is programmed to digitize the statement and make a search, comparing the code name to each code name in memory. If the code name is not matched, a machine audible is produced such as “Sorry that name is not recognized, please repeat it.” 
     6. If after multiple tries the name is not recognized the individual is given a parting machine audible and the copier moves to standby mode. 
     7. If the code name is matched, a machine audible is produced such as “Your account will be charged.” “Insert your originals into the feeder.” 
     8. After the original(s) have been placed into the feeder dialog between individual and machine continues with each human response being digitized and then matched with an inventory of possible human responses. For instance in answer to a machine request for “Number of copies?,” any numerical response such as “2,” “0,” “0,” would be understood and repeated by a machine audible followed by a human response, “yes.” The copier&#39;s request for information may include number of copies, single or double sided, collated or not, stapled sets, degree of magnification, degree of darkness, and so on. 
     9. If the individual does not speak English, the copier may be fitted with a language selection routine whereby immediately after recognizing the individual, a request for language is made by a machine audible such as “State your language of choice.” The copier&#39;s memory may be fitted to accept any number of languages and to operate using command in these languages. 
     10. When the copy job is completed, the individual removes copies and originals from the copier and upon sensing this action, the machine issues a machine audible such as “Thank you for using XYZ brand copy technology.” 
     While the invention has been described with reference to at least one preferred embodiment, it is to be clearly understood by those skilled in the art that the invention is not limited thereto. Rather, the scope of the invention is to be interpreted only in conjunction with the appended claims.
