Correlations of automated measures with manual coding. A–D Correlations of automatically extracted pause rate with manually coded measures of fluency and grammaticality. E–H Correlations of automatically extracted mean speech segment duration with manual coding. The mirror image between the upper and lower panels coincides with the strong negative correlation between speech duration and pause rate (see text). lvPPA, logopenic variant primary progressive aphasia; naPPA, non‐fluent/agrammatic primary progressive aphasia; svPPA, semantic variant primary progressive aphasia; sec, seconds; ppm, pauses per minute; wpm, words per minute; WFS, well‐formed sentences; DC, dependent clauses.
