Abstract
One or more example embodiments provides a method for speech control of a medical apparatus, a corresponding speech control apparatus, a medical system comprising the speech control apparatus, a computer program product and a computer-readable storage medium.
Claims20
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.

A speech control apparatus for speech control of a medical apparatus comprising:
- a first interface configured to capture an audio signal containing operator speech input for controlling the medical apparatus;
- a first evaluation unit configured to
- analyze the audio signal to obtain a first speech analysis result,
- recognize a first speech command from the operator based on the first speech analysis result;

- 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;
- a control unit configured to
- generate a control signal for controlling the medical apparatus based on the verification signal confirming the first speech command, the control signal being configured to control the medical apparatus according to the first speech command;
- and
- a second interface configured to input the control signal into the medical apparatus.
