I am using relative intensity as a metric for the degree of lenition in voiced stops. Several other papers use this metric but report the minimum pitch: (Warner and Tucker 2011: 1609 & Carrasco, Hualde and Simonet 2012: 156) Why do you need to report the minimum pitch when working with intensity? How does minimum pitch affect intensity?
