ABSTRACT:
A method and apparatus using a probabilistic network to estimate probability values each representing a probability that at least part of a signal represents content, such as voice activity, and to combine the probability values into an overall probability value. The invention may conform itself to particular system and/or signal characteristics by using some probability estimates and discarding other probability estimates.
