First Claim
Patent Images
1. A system, comprising:
- an audio device configured to receive an audio input from a user;
a speech recognition processor in communication with the audio device, the speech recognition processor configured to recognize at least one voice command from the audio input; and
an electronic device separated from the speech recognition processor and in communication with the speech recognition processor, the electronic device configured to;
determine whether the at least one voice command is valid and includes a safety-critical command;
present a preview of the at least one voice command when the at least one voice command includes a safety-critical command; and
execute the at least one voice command only after receiving an explicit confirmation from the user when the at least one voice command includes a safety-critical command.

Abstract
Voice-operable avionic systems and methods supporting utilization of speech recognition to facilitate control of avionic systems are disclosed. Utilizing speech recognition to control avionic systems may help reduce the head-down time of the flight crew. Safety features may also be implemented to ensure safety-critical commands are carried out as intended when commands are received through speech recognition. In addition, voice-operable avionic systems configured in accordance with embodiments of the inventive concepts disclosed herein may be implemented in manners that can help reduce the complexity and cost associated with obtaining certifications from aviation authorities.

12. A method, comprising:
-
receiving an audio input from a user; processing the audio input to recognize at least one voice command from the audio input; determining whether the at least one voice command is valid; processing the at least one voice command when the at least one voice command is determined to be valid, further comprising; determining whether the at least one voice command includes a safety-critical command; presenting a preview of the at least one voice command when the at least one voice command includes a safety-critical command; and executing the at least one voice command only after receiving an explicit confirmation from the user when the at least one voice command includes a safety-critical command. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A system, comprising:
-
an audio device configured to receive an audio input from a user; a speech recognition processor in communication with the audio device, the speech recognition processor configured to recognize at least one voice command from the audio input; and an avionic system separated from the speech recognition processor and in communication with the speech recognition processor, the avionic system configured to; determine whether the at least one voice command is valid; determine whether the at least one voice command includes a safety-critical command; present a preview of the at least one voice command when the at least one voice command is valid and includes a safety-critical command; execute the at least one voice command only after receiving an explicit confirmation from the user when the at least one voice command is valid and includes a safety-critical command; and execute the at least one voice command immediately when the at least one voice command is valid and does not include a safety-critical command. - View Dependent Claims (20)
