1. Method for the voice-controlled initiation of actions by means of a limited circle of users, whereby said actions can be carried out in an appliance, comprising the following features:

  • (a) On the basis of the voice pertaining to at least one user of the user circle of the device, the device, for at least one operating mode selected by the respective user, is trained in at least one speech training phase to be initiated by the user such that (a1) at least one of the users, with respect to at least one action, enters at least one reference speech utterance into the device, whereby said reference speech utterance is respectively allocated to the action, (a2) a reference speech pattern is generated from the reference speech utterance by speech analysis, whereby the reference speech pattern, given a plurality of reference speech utterances, is generated when the reference speech utterances are similar, (a3) the reference speech pattern is allocated to the action, (a4) the reference speech pattern is unconditionally stored with the allocated action or is only stored when the reference speech pattern is not similar to the already stored other reference speech patterns which are allocated to other actions, (b) the respective user, in a voice recognition phase, enters a recognition speech utterance into the device for the operating mode of the device selected by the user, (c) a recognition speech pattern is generated from the recognition speech utterance by speech analysis, (d) the recognition voice pattern is compared to at least a part of the reference speech patterns, which are stored for the selected operating mode, such that the similarity between the respective reference speech pattern and the recognition speech pattern is detected and such that a similarity rule of precedence of the stored reference speech patterns is formed on the basis of the detected similarity values, (e) the voice-controlled initiation of the action to be carried out in the device by the user—

    whereby said voice-controlled initiation is caused by the recognition voice utterance—

    is admissible when the recognition speech pattern is similar to the reference speech pattern which is first in the similarity rule of precedence or when the recognition speech pattern is similar to the reference speech pattern which is first in the similarity rule of precedence and when said recognition speech pattern is not similar to the reference speech pattern situated at the n-th position in the similarity rule of precedence, whereby another action is allocated to the reference speech pattern situated at the n-th position in the similarity rule of precedence than to the action that is allocated to the reference speech pattern which is first in the similarity rule of precedence and whereby the reference speech patterns, from the first to the (n−

    1)th position with respect to the similarity rule of precedence, are allocated to the same action, (f) the action, which is allocated to the reference speech pattern situated first in the similarity rule of precedence, is only carried out when the recognition voice utterance, in a speech recognition phase, entered by the user into the device for the operating mode of the device selected by the user has been recognized as allowable.
