Supplementary Information for: "Speech power spectra: a window into neural oscillations in Parkinson's disease"

The PDF files in this repository provide supplementary information for the conference paper presented at Interspeech (Rotterdam, The Netherlands, August 17–21, 2025), titled "Speech power spectra: a window into neural oscillations in Parkinson’s disease" In the article, we analyzed the power spectral density of speech samples from the PC-GITA dataset, focusing on both sentence and read text tasks. Due to space limitations, not all plots could be included in the conference paper. Therefore, the boxplots with statistical tests ("combined_boxplots.pdf") and the power spectral density plots ("combined_mtp_psd.pdf") for all sentences are uploaded here.
