ABSTRACT:
The present invention relates to a method for setting terminal-apparatus-specific parameters of a communication terminal apparatus by an operator.
In known methods, the operator inputs a character sequence via a keyboard of the terminal apparatus in order to achieve the state of modification for a particular parameter, whereupon, dependent on further key actuations, a control means carries out particular parameter settings allocated to these key actuations. In some communication terminal apparatuses, the operator is hereby supported only by an operator handbook, from which the operator can learn the key actuation sequence for the setting of a terminal-apparatus-specific parameter. Other communication terminal apparatuses with display means enable a menu-controlled setting of terminal-apparatus-specific parameters by displaying the respective current state of the control means or by requesting the actuation of desired keys with the aid of an alphanumeric display. However, due to the multiplicity of functions, performance features and parameters that can be adjusted, activated or deactivated in menu-controlled fashion, for such terminal apparatuses with display means the operator is also dependent on a user handbook in order to achieve the setting of terminal-apparatus-specific parameters in a desired menu level.
Communication terminal apparatuses are already known in which specific functions, such as the activation of performance features or the outputting of call numbers, can be controlled by speech commands with the aid of speech recognition means.
Thus, from the publication Elektrisches Nachrichtenwesen, Volume 59, No. 3, 1985, from the article “Spracherkennung und Sprachsynthese fur Dienste von Nebenstellenanlagen,” H. Mulla, J. F. Vaughan, pages 273 to 280, a private branch exchange is known that enables a speech-controlled dialed call. Here, in particular the speech-controlled retrieval of performance features such as “transfer,” “three-way conference,” “hold” and “automatic callback” are described. In the same publication, in the article “Sprachgesteuerter Rufnummerngeber”, M. Immendörfer, pages 281 to 285, a means is specified that, in addition to a telephone, can be connected to a telephone installation in order to enable a speech-controlled dialing process and in order to activate some user-friendly functional features, such as for example the performance feature “redialing.”
From U.S. Pat. No. 5,335,261, in addition a radio telephone is known with a speech recognition means for the evaluation of dialing information inputted by means of speech and for the outputting of this dialing information.
EP 0 194 387 A2 additionally specifies a speech-controlled telephone for the speech-controlled outputting of a call number, whereby in a preferred construction the manner of functioning of a speech recognition means and the training process for matching the reference pattern of the speech recognition means to the specific utterance of an operator are specified in detail.
From DE 36 08 497 A1, a method is known for setting up a telephone connection via an operating means of a remote terminal apparatus, in particular of a car telephone, in which a user acoustically inputs a desired dialing destination using words and/or numerals via a microphone of the operating means, the acoustic input is evaluated in the operating means, a telephone connection is set up to the result of the evaluation in the operating means, and a synthetically produced speech output takes place via a loudspeaker of the operating means for acoustic user guidance. In addition, it is known that the operating means is activated by picking up a hand apparatus or by the spoken input of an activation command word via a separate microphone switched ready for operation, that the user is requested via the loudspeaker to input the dialing destination, that after the acoustic input of the dialing destination an evaluation takes place in a speech recognition and speech synthesis unit of the operating means, that a recognized dialing destination is acoustically confirmed to the user, and that an automatic connection setup takes place after a predeterminable lead time, if the user does not cause an interruption within the lead time by means of the acoustic input of a correction command word or by laying down the hand apparatus. In addition, it is provided that for the storing of dialing destinations, a user controls the speech recognition and speech synthesis unit into a storage mode by means of the acoustic input of a storage command word, that the storage mode is acoustically confirmed and that the user is requested to input a memory space number, that the inputted memory space number is acoustically confirmed, that the user is acoustically requested to make a spoken input of the subscriber name, that after the spoken input of the subscriber name has taken place the user is acoustically requested to input the associated call number, that after the input of the call number the user is again acoustically requested to make a spoken input of the subscriber name in order to initiate a recognition test that acoustically confirms to the user a correct recognition, acoustically repeats the dialing destination, and, after the user has given the acoustic confirmation, storage takes place under the indicated memory place number, and that, after the acoustic input of an end command word, the storage mode is switched off.
From DE 94 15 045 U1, a telephone apparatus is known in which the user is enabled to accept an incoming call even from a location spatially remote from the telephone apparatus, in which a handsfree means allocated to the telephone apparatus is remotely actuated by the input of speech, preferably by the speaking of a previously defined code word.
From EP 0 194 387 A2, a speech-controlled telephone is known that is able to learn the speech of the user by means of the visual representation of the speech commands spoken by the user in the form of words and numbers. In addition, the user of the telephone can store the names and call numbers of persons who are frequently to be dialed. When such a person is to be called, the user of the telephone utters only the corresponding name of the person to be called and a dialing command. For this speech-controlled dialing, in a first embodiment the telephone comprises a specific speech recognition circuit and a separate control means, as well as, in a further embodiment, a handsfree arrangement with a microprocessor-controlled speech recognition and a telephone controlling. For problem-free speech-controlled operation, in the telephone the speech sequences inputted by the user are compared with stored reference patterns (speech templates) before the stored call number belonging to the speech sequence is dialed after the input of a dialing command.
From U.S. Pat. No. 4,439,638, a function-producing system is known with a noise-activated control system for telephones, in which a reciprocal effect is provided between the caller and the receiver in the form of a feedback arrangement. The only treatment to be carried out here is the production of noises in the form of numerals or other symbols at the receiver end, and in the form of response numerals or other symbols at the caller end. By this means, the system becomes completely independent of pushbutton keys or dialing disks. By this means, it is in particular possible to avoid the use of these keys or dialing disks, not only at the calling and receiving apparatuses, but also at the switching centers. In the switching centers, an operator would even no longer be necessary, because the voice, or another noise at the calling end of the system, would trigger directly.
The object of the present invention is to indicate a method for setting terminal-apparatus-specific parameters of a communication terminal apparatus that is easy to operate and that operates reliably.
