The present contribution aims at inventoring the microprosodic phenomena already abundantly described in the past for languages such as English and French (see [1] for a commented review of these studies). We propose to measure their usefulness in an automatic processing and also to estimate the expected confidency of microprosodic "corrections" - at least in an automatic way - by studying each parameter separately and by presenting statistical distributions of the different phenomena measured on isolated french word corpora uttered by several speakers.
