Abstract :
The log likelihood measure has been widely used in speech recognition for comparing speech signals. Recently it has been proposed as a measure for assessing the quality of coded speech. In this paper we present an interpretation of the log likelihood ratio measure within the theoretical framework of a waveform coder distortion model.
