Objective analysis of Parkinson’s disease (PD) based on quantification of hypokinetic dysarthria (HD) is a modern and prospective method of diagnosis, assessment, monitoring and treating of the disease. It has been shown that approximately 60 – 90% of patients with PD suffer from HD. HD is characterized by impaired respiration, phonation, articulation, prosody and speech fluency. Objective quantification of the previously mentioned speech flaws in HD can provide valuable information about the underlying mechanism of HD and also PD, which can often be hidden above the human’s perception and therefore can barely be identified by a subjective examination at the clinic.

Dysarthric speech quantification tool is an open-source library comprising a variety of speech features conventionally used in the field of acoustic analysis of dysarthric speech. It is programmed in the Python programming language and it built on modern, standard libraries such as NumPy, SciPy, or Matplotlib, see https://www.scipy.org/. This tool also provides functions to handle the speech recordings (loading, saving, etc.), perform a speech signal pre-processing (peek finding, interpolation, segmentation, etc.), and also classes to represent speech signals and the patients with HD in PD. This tool provide a quick, easy-to-use, objective quantification of speech flaws associated with the presence of HD.
