Optimization of a speech recognizer for aircraft environments

Volker Schless, Fritz Class, Peter Sandl

Speech recognition in aircrafts can greatly simplify operation of equipment in both military and civil environments. This paper describes the development of specialized recognizers for two military applications: One for assisting a jet pilot wearing a breathing mask and another for a radar evaluator within an aircraft (similarly to AWACS). In both cases it is not practical to collect sufficient speech data under real conditions for a robust specialized recognizer. This paper describes two methods for overcoming this data problem and building a recognizer with minimal effort: retraining the baseline system with real application data and combining the baseline system with a new trained system. These methods greatly improved the performance of the baseline system (US English recognizer adapted to car environment).
