Hypokinetic dysarthria (HD) is a frequent speech disorder associated with the presence of idiopathic Parkinson’s disease (PD). Recent research in this field of science has reported that impairment of speech prosody (dysprosody) in HD has a detrimental impact on speech naturalness (emotions, accent, stress, rhythm, etc.). Dysprosody is generally characterized by impaired speech melody and often results into quiet and monotonous speech. Using modern signal processing methods, it is possible to quantify these speech flaws. Specifically, in the case of dysprosody in HD, the analysis of fundamental frequency and squared energy operator can be used.
Prosodic impairment analysis tool provides an easy quantification and visualization of melody of speech. This tool uses functions specifically designed to extract speech features describing prosodic flaws in HD, namely: monopitch and monoloudness. Graphical users interface enables user to easily load an input *.wav file and extract the prosodic features, update the table of features, and plot the fundamental frequency and squared energy operator estimation, by one click. This GUI also enables user to export the table of features to the output *.xlsx or *.csv files.
