Speech recognition has become a part of everyday life. Voice assistants such as Alexa, OK Google and Siri can carry out many useful functions, such as allowing us to enter a new address into our navigation system without taking our hands off the steering wheel. But speech recognition software can also be used to assist air traffic controllers communicating with aircraft in flight and on the ground. It can save them time and even reduce the aircraft’s fuel consumption. For many years, the DLR Institute of Flight Guidance has been researching speech recognition software and testing it in new areas of application. But how does this software work, and what other benefits does it offer? Photo: Fraport AG
