The AFRL/RI Audio Group is involved in all aspect of speech processing and is a unique combination of linguists, mathematicians, DSP engineers, software engineers, and intelligence operators. This combination of individuals allows us to tackle a wide spectrum of topics from basic research such as channel estimation, robust word recognition, language and dialect identification, and confidence measures to the challenging transitional aspects of real-time implementation, GUI design, and concepts of operations. The Audio Group also has significant thrusts in noise estimation and removal; speaker identification including open-set identification, keyword spotting, robust feature extraction, language translation, analysis of stressed speech, coding algorithms along with the consequences of the compressions schemes, watermarking, co-channel mitigation, and recognition of background events in audio recordings.
