1. A method for speech control of a medical apparatus, the method comprising:
capturing an audio signal containing operator speech input for controlling the medical apparatus;
first analyzing the audio signal to obtain a first speech analysis result;
recognizing a first speech command from the operator based on the first speech analysis result;
ascertaining a verification signal for the first speech command, the ascertaining including,
second analyzing the audio signal to obtain a second speech analysis result, the second analyzing including applying a computational linguistics algorithm to the audio signal, and the computational linguistics algorithm being configured to only recognize safety-critical speech commands,
recognizing a second speech command from the operator based on the second speech analysis result, and
comparing the first speech command and the second speech command to obtain a comparison result,
the verification signal confirming the first speech command based on the comparison result satisfying a conformity criterion;
generating a control signal for controlling the medical apparatus based on the verification signal, the control signal being configured to control the medical apparatus according to the first speech command; and
inputting the control signal into the medical apparatus.
