I am analyzing dyadic conversations for speech characteristics through pre-written script. I spoke with an expert in speech analysis prior to data collection as an introduction to praat. He suggested a few parameters I could follow regarding pitch, silence duration, and silence threshold but did not really get into the analysis or the data sets. I have looked at the standard settings given in the script, which are just slightly different than the expert suggested. What is the benefit of adjusting such parameters in one direction or the other? I need to be able to justify whichever parameters I use, which could easily follow the script, as it had been published. However, the expert is familiar with this specific scenario/dataset. Thus, what are the benefits of adjusting and how would one justify doing so with these parameters?
Script parameters: 50Hz pitch, -25dB silence threshold, 0.3 silence duration Suggested parameters: 150 Hz pitch, -30db silence threshold, 0.2-0.25 silence duration
