The recognition process of isolated words use distance measures to determine if the word corresponds to one of its vocabulary. In this investigation Itakura distance measure was used to compare the segments of white noise of two signals with different relationships of direct and reverberant energy densities. Interesting data is obtained from the distance measure in the function of the position of the microphone in the room in which a white noise source is continuously working. These results could be useful to develop a new methodology to measure the word intelligibility in a room. There were carried out some comparative measurements with Rasti and intelligibility test.
