Description: Currently, KalScott is executing a Phase II project where one-way VHF voice comms transmissions are broadcast from a UAV. The message can then be heard by air traffic controllers and pilots in manned aircraft using legacy VHF radios. We now propose to develop and demonstrate two-way communications, by incorporating speech-to-text capability, which will enable the UAV to comprehend VHF messages from a human agent (such as a base air traffic controller), and respond appropriately. In the proposed Phase II-E project, we will conduct device development, and testing (in the lab, field and flight).

Benefits: This will allow UTM controllers to direct the UAV using legacy VHF airband comms. This will enable safer operations of unmanned aircraft in mixed use airspace where manned aircraft, helicopters, eVTOLs etc will be operating.

The voice control of unmanned vehicles (air, ground, sea) will be easier for users, specially in dense environments. This is particularly of use in government air bases where unmanned ground vehicles are being evaluated for airfield operations such as debris removal, equipment towing, etc.
