A construction of a speech/ nonspeech discriminator

In this paper we present our studies on construction of a speech/non speech discriminator. The discriminator’s task is to distinguish speech signal from non speech signal in a room such as sounds of broken glass, door shutting, chair falling, water in toilette, etc. A set of features is estimated and selected to be used in speech/non-speech discrimination. Different classification models using those features are also evaluated. Basing on results of those evaluations, we construct a speech/non-speech discriminator which can detect the presence of speech signals in a room. This discriminator is to be applied in a sound analysis system within the framework of a telemedicine project.
