1. A method for utilizing audio commands onboard an aircraft, the method comprising:
- identifying a flight phase for the aircraft, resulting in an identified flight phase;
receiving an audio input, resulting in received audio input;
filtering the received audio input in a manner that is influenced by the identified flight phase for the aircraft, resulting in filtered audio input; and
validating the filtered audio input as a first voice command of a first plurality of possible voice commands, wherein validating the filtered audio input comprises;
determining a plurality of possible initial command words based on the first plurality of possible voice commands, each possible initial command word of the plurality of possible initial command words corresponding to an initial command word of a respective voice command of the first plurality of possible voice commands;
recognizing a first portion of the filtered audio input as a first command word of the first voice command based on the plurality of possible initial command words;
determining a plurality of possible second command words that may follow the first command word of the first voice command based on a subset of the first plurality of possible voice commands, wherein the first command word corresponds to an initial command word for each possible voice command of a subset of the first plurality of possible voice commands and each possible second command word of the plurality of possible second command words corresponds to a second command word of a respective voice command of the subset; and
recognizing a second portion of the filtered audio input as a second command word of the first voice command based on the plurality of possible second command words.

11. A method for utilizing audio commands onboard an aircraft, the method comprising:
-
identifying a flight phase for the aircraft, resulting in an identified flight phase; receiving an audio input, resulting in received audio input; filtering the received audio input in a manner that is influenced by the identified flight phase for the aircraft, resulting in filtered audio input; automatically validating the filtered audio input as a first voice command of a first plurality of possible voice commands when a criterion associated with the first voice command corresponds to a first safety level; and validating the filtered audio input as the first voice command in response to a confirmation when the criterion associated with the first voice command corresponds to a second safety level.

12. A system for an aircraft comprising:
-
an avionics system onboard the aircraft; an audio input device onboard the aircraft, the audio input device being capable of receiving audio input; a data storage element comprising a first plurality of possible voice commands; and a processing system coupled to the avionics system, the audio input device, and the data storage element, wherein the processing system is configured to; identify a flight phase for the aircraft, resulting in an identified flight phase; filter the audio input based on the identified flight phase, resulting in filtered audio input; recognize the filtered audio input as a first voice command of the first plurality of possible voice commands by; determining a plurality of possible initial command words based on the first plurality of possible voice commands; recognizing a first portion of the filtered audio input as a first command word of a first voice command of the first plurality of possible voice commands based on the plurality of possible initial command words; determining a plurality of possible second command words that may follow the first command word of the first voice command based on a subset of the first plurality of possible voice commands, wherein the first command word corresponds to an initial command word for each possible voice command of the subset; and recognizing a second portion of the filtered audio input as a second command word of the first voice command based on the plurality of possible second command words; and provide the first voice command to the avionics system in response to recognizing the filtered audio input as the first voice command, wherein the avionics system is configured to execute the first voice command. - View Dependent Claims (13, 14, 15)
