The high frequency( HF) communication is the primary means of airborne remote distance commu-nication . Through analyzing the failure risk of HF radio under strong interference and remote distance condi-tions,an airborne high frequency emergency communication scheme based on speech recognition is designed. The speech signal is recognized and the semantic information is transmitted in this scheme. In order to insure the implementation of the given emergency communication scheme, embedded speech recognition system, speaker adaptation techniques and noise robust speech recognition methods are adopted to improve the accu-racy. So emergency communication support for pilots can be ensured in aforementioned conditions.
