Assessing acoustic reduction: Exploiting local structure in speech. In Proceedings of the 12th Annual Conference of the International Speech Communication Association (Interspeech 2011), Florence, Italy
This paper presents a method to quantify the spectral
characteristics of reduction in speech. Hämäläinen et al.
(2009) proposes a measure of spectral reduction which is able
to predict a substantial amount of the variation in duration that
linguistically motivated variables do not account for. In this
paper, we continue studying acoustic reduction in speech by
developing a new acoustic measure of reduction, based on
local manifold structure in speech. We show that this measure
yields significantly improved statistical models for predicting
variation in duration.
