Scatter plots for the correlations between the intelligibility score and respective speech dysarthria clinical anchor score. From upper left to lower right: DE PD correlation with the MDS-UPDRS speech item; CO PD correlation with the MDS-UPDRS speech item; CZ PD correlation with the MDS-UPDRS speech item; CZ PSP DE PD correlation with the NNIPPS speech item; CZ HD correlation with the UHDRS dysarthria score; and CZ ALS correlation with the ALSFRS-R speech item (note that ALSFRS-R has an inverse relationship to disease severity, unlike the other scales in which higher scores mean greater severity). DE, German; CO, Colombian Spanish; CZ, Czech.
