Definitions

  • the invention relates to a method for access control according to the preamble of claim 10 and a corresponding Access control arrangement.
  • the electronic speaker verification or identification uses methods similar to speech recognition. Your goal however, does not consist in a change of utterances in text, but in the identification or verification a person because of their speech.
  • the well-known Speaker verification systems are relatively complex and expensive and have therefore not yet been widely used.
  • the problem that conventional ones also contributed to this Speech recognition systems in one also referred to as "enrollment" Process initialized to the user or users or have to be trained. This problem particularly affects disadvantageous when a user has access to different Room areas, buildings, devices, networks or similar per Speaker identification must or would like to and always the individual system must train beforehand.
  • This task is in terms of their device aspect by an access control arrangement with the features of the claim 1 and with regard to their procedural aspect by a Method with the features of claim 10 solved.
  • the invention includes the basic idea that Overall process of access control via speaker identification (from voice input to opening or blocking access) between two subsystems or sub-procedures to split, one of the subsystems or one of the Process sections for a variety of admission control situations is usable. It is a mobile Voice input unit that is part of the speaker identification process executes while the other part of the overall arrangement - More specifically: a variety of possible overall arrangements - in each case the actual access control effecting access control device exists. In this will executed another part of the speaker identification, and here is especially one for user authorization used vocabulary saved.
  • this comprises or each access control device in addition to a corresponding one Control unit vocabulary memory a control word transmission unit for transferring words from the stored vocabulary to the voice input unit, and the voice input unit has correspondingly a control word receiving unit for receiving the Control words, a microphone and a downstream LF stage for voice input, a speaker feature extraction level (Speech recognizer) and a speaker feature transmission stage for transmission an extracted set of speaker features to the respective access control device.
  • the latter also has a corresponding speaker feature reception stage, one Speaker feature reference memory for storing speaker features predetermined user and a speaker feature comparator unit, which depending on the result of a Comparison of the currently determined speaker characteristics with pre-stored speaker features an access enable signal or generated access blocking signal.
  • the mobile voice input unit expediently comprises one between the control word receiving unit and the speaker feature extraction stage or switched the speech recognizer Buffer for those received by the access control device selected control or identification words, as well as the access control device expediently one between the speaker feature receiving stage and the speaker feature comparing unit switched speaker feature cache for those received by the voice input unit Has speaker characteristics.
  • These memories can be permanent or be semi-permanent and for one and the same access control device in cooperation with one and the same Voice input unit in an overall system of several Voice input units and / or access control devices, depending on concrete system configuration, a more or less long-term Storage of a control or identification word set or the characteristics of an opposing access person to back up.
  • the next task of the mobile voice input unit is then in these words spoken by the user in one To present verification dialog to the user To request voice input and record his speech.
  • Known displays with menu navigation are used for this purpose and audio front ends.
  • Communication between the voice input device and the Access control device or the access control devices expediently runs as wireless communication, especially on a radio link.
  • Radio link based on the Bluetooth or DECT standard (for example with a cordless telephone) and the use a cellular network with voice and data transmission viewed the GSM or UMTS standard.
  • the vocabulary transmission unit and the speaker feature reception stage of the respective access control device and the Vocabulary receiving unit and the speaker feature transmission stage the voice input unit as radio transmission or reception units educated.
  • the use is also fundamental of proven infrared interfaces possible.
  • the speaker feature extraction stage with a phoneme-based hidden Markov model it is not necessary that those serving as a reference pre-stored speaker characteristics from the currently used as control words serving words were obtained. Rather, you can the access control device for every user willing to access and / or with every access attempt or also in periodic Intervals new control words can be specified without a new training of the speech recognizer in the speech input unit would be required.
  • training or enrollment plays an important role. This is basically in two parts to subdivide, namely the inclusion of a word or a Speech and the calculation of characteristics on the Voice input unit on the one hand and the storage of the features with a speaker identification code on an access device on the other hand. These two parts of the enrollment can too be carried out separately in time, and in particular can be obtained once on a voice input device Transfer speaker features to different access devices become.
  • the access control devices 3 'to 9' each have a vocabulary memory 3a to 9a, a control word selection stage connected to this 3b to 9b and one connected to it Control word transmission stage 3c to 9c for storage, selection and submission of tax words for speaker verification of a user who is willing to access the voice input unit 11 on.
  • the currently determined speaker characteristics are in the access control devices 3 'to 9' each through a speaker feature receiving stage 3d to 9d received, which in turn with a speaker feature comparator unit 3e to 9e is.
  • a speaker feature reference memory 3f to 9f for storing speaker characteristics of a predetermined user group as a reference for speaker verification connected and serves to compare the current determined co-stored speaker feature vectors and to output a measure of conformity in the result of a statistical comparison process.
  • Threshold discriminator a classifier level (Threshold discriminator) 3g to 9g for the classification of the Comparison result at a predetermined threshold of Similarity measure.
  • This classifier level ultimately gives depending on the result of the threshold discrimination an access enable signal or access lock signal as final control signal of the memory verification.
  • the Threshold values can be set for the individual access control devices in Depends on the desired level of protection against unauthorized persons Use of the respective space to be secured or Systems can be chosen differently. Likewise, the vocabulary of the individual access control devices selected differently be, and the scope of each of the total vocabulary selected control word set or control text for the speaker verification can be of different sizes.
  • the user who is willing to access is assigned to the user Execution by (not shown) evaluation of to the access control devices - which, of course, are a mobile radio transceiver must have - transmitted data from the SIM card of the mobile phone 1. This additionally increases the Security against unauthorized access to the devices, since already the use of the mobile phone 11 only after activation of one only the PIN known to the user is possible.
  • Another embodiment sees the use of Bluetooth technology for wireless communication between a voice input unit and the access control devices.
  • a voice input unit especially for the home, is used here, for example, a retrofitted with a Bluetooth module Cordless telephone or a PDA or handheld PC, into which the speaker feature extraction level mentioned above is integrated.
  • the presence of the required Audio components also enable a cost-effective one Realization of the voice input unit.
