large RMS, small autocorrelation

Transient-(ness??) isn't really a quality so much as confidence
in an event boundary. For untreated speech (no dynamic compression)
simple time domain ratio of peak amplitude in short windows. Speech
often wants us to look for two or three specific types of transient:
plosive or fricative stops/glottals etc.
