Method and system for operating a vehicular electronic system with voice command capability

An avionics system comprising:

• at least one microphone configured to detect voice commands and generate voice command signals representative thereof;
• and
• a processing system in operable communication with the microphone, the processing system being configured to:
• receive a first voice command signal from the at least one microphone, the first voice command signal being indicative of a request to perform a first type of avionics system function;
• perform the first type of avionics system function in response to said receiving the first voice command signal;
• receive a second voice command signal from the at least one microphone, the second voice command signal being indicative of a request to perform a second type of avionics system function, the second type of avionics system function having a hazard level that is higher than that of the first type of avionics system function;
• and
• perform the second type of avionics system function in response to said receiving the second voice command only after a condition is detected that is indicative of a confirmation of the request to perform the second type of avionics function.

An avionics system comprising:

• a speaker configured to generate an artificial voice command;
• a microphone configured to detect the artificial voice command and generate an artificial voice command signal representative thereof;
• and
• a processing system in operable communication with the speaker and the microphone, the processing system being configured to:
• provide the speaker with a test voice command signal such that the speaker generates the artificial voice command;
• receive the artificial voice command signal from the microphone;
• and
• compare the test voice command signal with the artificial voice command signal.
