- W996890339 abstract "Without information there is no life. In the course of evolution, nature made use of nearly every physical principle to enable organisms to gain information from and about their environment, and to affect their environment. In animal realm, sound is one of the most prominent communication means, suited for long and close distances. Acoustic monitoring of farm animals may serve as an efficient management tool to enhance animal health, welfare, and farm efficiency, and in general as a useful tool in animal ethology. The final goal is a call-recognizer to identify the meaning of sounds issued by animals. Such call-recognizer must be able to recognize the meaning of calls, independent from the individual animal and a more or less noisy environment. As a probabilistic method during the learning or training phase, feature vectors from known calls are calculated. From feature vectors of calls with the same meaning reference patterns are built and stored. To recognize a call it has to be calculated in the same way. The system then determines the reference pattern that is most similar to the pattern to be recognized and outputs the meaning. Despite the vocabulary size and complexity of human speech, which is unique in animal realm, sound production and reception have several commonalities among vertebrates. This encourages to adapt methods and experiences from speech recognition in order to recognize animal vocalization and sounds. In speech recognition, double stochastic processes, such as Hidden Markov Models (HMMs), have proven to be very efficient. They were applied here to recognize the meaning of different animal calls in two studies, using utterances of cows as an example, and to diagnose pathological coughing of pigs. The results revealed that probabilistic methods like HMMs are well suited for monitoring animals by identifying the meaning of their vocalization and to diagnose their health status." @default.
