Abstract: Acoustic analysis in phonetics presents anopportunity to quantify meaningful differences in speech sounds. Recently, however, methodological research has raised concerns about the degree of variation in acoustic methodology and its impact on generalizability of the results. While researchers often have intuitions of best practices for selecting appropriate features, there is little quantitative investigation of how acoustic features are used in empirical studies. This paper presents the results of a survey of the methodology in a sample of papers from the proceedings of this conference at two time points 20 years apart, with a focus on the target contrast, parameters used, and measurement choices. The results identify themes in acoustic features across contrast types and identifies potential areas for further development of acoustic parameters.
