Method for the computer-aided training of a robot using speech dialogue, wherein the robot is a predefined robot having a speech dialogue system by way of which a user is able to communicate with the predefined robot through speech, wherein: - a training dialogue is called in the predefined robot in order to teach the predefined robot to use one or more speech expressions based on speech communication with a user; - in response to a speech expression that is input into the speech dialogue system by the user by way of speech input in the course of the training dialogue and belongs to a predefined expression category, a multiplicity of concepts is checked, these corresponding to one another and comprising a concept stored locally in the predefined robot and one or more concepts that are stored in one or more further robots (R2, R3, R4, R5) to which the speech expression input by the user is conveyed, wherein a respective concept from the multiplicity of concepts describes the admissibility of speech expressions from the predefined expression category for a speech output performed by the predefined robot, and the check of a respective concept delivers a first or second result, wherein, according to the first result, the speech expression input by the user is admissible and, according to the second result, the speech expression input by the user is inadmissible; - a consistency check is performed based on the results of the check of the multiplicity of concepts, wherein the consistency check is successful if the check of at least a predefined number of concepts delivers the same result, wherein the predefined number is greater than 50% of the number of concepts contained in the multiplicity of concepts; - in the event of a successful consistency check, the speech expression input by the user is stored in the predefined robot if the result delivered by the check of at least the predefined number of concepts is the first result, and the speech expression input by the user is discarded if the result delivered by the check of at least the predefined number of concepts is the second result; - in the event of an unsuccessful consistency check, the speech expression input by the user is discarded. - a training dialogue is called in the predefined robot in order to teach the predefined robot to use one or more speech expressions based on speech communication with a user; - in response to a speech expression that is input into the speech dialogue system by the user by way of speech input in the course of the training dialogue and belongs to a predefined expression category, a multiplicity of concepts is checked, these corresponding to one another and comprising a concept stored locally in the predefined robot and one or more concepts that are stored in one or more further robots (R2, R3, R4, R5) to which the speech expression input by the user is conveyed, wherein a respective concept from the multiplicity of concepts describes the admissibility of speech expressions from the predefined expression category for a speech output performed by the predefined robot, and the check of a respective concept delivers a first or second result, wherein, according to the first result, the speech expression input by the user is admissible and, according to the second result, the speech expression input by the user is inadmissible; - a consistency check is performed based on the results of the check of the multiplicity of concepts, wherein the consistency check is successful if the check of at least a predefined number of concepts delivers the same result, wherein the predefined number is greater than 50% of the number of concepts contained in the multiplicity of concepts; - in the event of a successful consistency check, the speech expression input by the user is stored in the predefined robot if the result delivered by the check of at least the predefined number of concepts is the first result, and the speech expression input by the user is discarded if the result delivered by the check of at least the predefined number of concepts is the second result; - in the event of an unsuccessful consistency check, the speech expression input by the user is discarded.
