The ultimate goal of the present study is to develop a focus detector for Swedish integrating several sources of information. To that end we have examined the extent to which different measures of overall intensity and high frequency emphasis can be used to detect focus in read and spontaneous Swedish. It is shown that focused words can be detected with a rate approximating 70% under favorable conditions. Furthermore, as the effectiveness of the measures varies between speakers and the position of the focused word in the phrase, we believe that it would be advantageous to include both measures of intensity and of emphasis in a focus detector.
