Talker-to-listener distance effects on the variations of the intensity and the fundamental frequency of speech

In this study we focus on the relationship between the talker-to listener distance (TLD) and the dynamics of speech intensity and fundamental frequency. A new experiment for the extraction of pertinent information from prosodic parameter variations for different TLDs is described. The proposed new recording protocol allows simulating a real TLD by using acoustically insulated rooms. We propose to measure the dynamics of ID and intensity by using the variation between the minima and the maxima of their contours and the initial/final slopes of f0. The results show a strong correlation between these parameters and the TLD.
