    SIGNAL in Science
SIGNAL has been used to analyze evolutionary call behavior of the male Túngara frog. The Michael Ryan Lab at the University of Texas studies the effect of sexual preference on the communication system, examining the advantages and costs of different call behaviors. Read more |
William Clapham of the U.S. Department of Agriculture uses SIGNAL to measure the forage consumed by free-grazing beef cattle. SIGNAL automatically detects, classifies, and quantifies streaming acoustic recordings of biting and chewing sounds with an accuracy of 95% relative to trained human observers. Read more |
Vincent Janik at the University of St. Andrews showed that bottlenose dolphins produce individual signature whistles that convey identity information independent of the caller’s voice features. He used SIGNAL to extract spectral behavior from recorded calls, then synthesize new "voice-free" playback calls based on spectral behavior alone. Read more |
