ASR for Simulation Training

Speech Recognition for Simulation Training

Automatic Speech recognition for simulation training has been used for over three decades. However, it was not until 2001 that the application of ASR in the training domain saw its first widespread success. It was at this time that the technology had reached sufficient maturity that it was a mandatory requirement for The United States Air Force contract, for the purchase of up to one hundred air traffic controller training simulators.

Air Traffic Control Simulators

An air traffic control training simulator creates computer-generated aircraft. The aircraft is displayed on various devices such as radar screens and for an airport simulator, as seen in the picture below,  they are displayed on an out of the window visual scene. Student air traffic controllers issue instructions to the aircraft on the appropriate radio frequency and traditionally, the control instructions are translated into computer inputs by role-players, which for ATC simulation are called role players or pseudo pilots. The computer inputs are in turn used to direct the actions of the simulated aircraft. An example of an ATC simulator in use can be seen here.

Adopting ASR in a simulation will reduce cost, add consistency, and improve realism.

The primary purpose of ASR for simulation training is to reduce or replace role players.

Simulator Role Players

Finding the personnel to serve as pseudo pilots can be a challenge to a large training organization and is accompanied in many situations by considerable expense. The USAF determined that as a result of supporting numerous overseas deployments, they would be unable to utilize human pseudo pilots Such an approach, would not be viable for the widespread distribution of simulation systems. They declared ASR in simulation training would be the key attribute of the winning system. Speech recognition would automate the pseudo-pilot role.

There are numerous challenges to be overcome in considering speech recognition for simulation training. If you overcome those challenges, the benefits to the training providers and the trainees are clear.

In the next article, we will discuss those challenges.
