A "flight-worthy" speech-recognition system has achieved a 98.5% word recognition success rate while in operation in a noise and vibration environment representative of the cockpit of a Westland Lynx helicopter, according to the UK Defence Evaluation & Research Agency (DERA). The DERA is working with GEC-Marconi Secure Systems to introduce voice control for systems and equipment in a range of fixed- and rotary-wing aircraft. The DERA says that the test programme has "...taken speech recognition from the research laboratories to a tool that is ready for use in airborne applications". The Lynx, was fitted with a 1,000 word speech recogniser, the ASR1000, including a tailored IMELDA noise processing "transform".
