Correlation of Utterance Length and Segmental Duration in Finnish Is Questionable

Jussi Hakokari, Tuomo Saarni, Jouni Isoaho, Tapio Salakoski, Correlation of Utterance Length and Segmental Duration in Finnish Is Questionable. In: Deborah Loakes Roland Göcke Denis Burnham Michael Wagner Janet Fletcher (Ed.), Proceedings of Interspeech 2008 incorporating SST 2008, 2008.

Abstract:

This paper examines the way acoustic segmental duration
correlates with utterance length in Finnish. It is commonly
assumed that shorter utterances are characterized by greater
segmental duration. However, that view has recently attracted
some criticism. We conducted an explorative study on two
linguistically uncontrolled Finnish-language speech corpora
by examining segmental duration as a function of utterance
length. We tested a hypothesis that the perceived differences
in duration are in fact caused by short utterances containing a
greater proportion of domain-edge effects, such as final
lengthening. Pearson correlations were calculated for the
timing information in different conditions. The results show
that the weak correlation holds no more if domain edges are
excluded from the material, suggesting there is no domainspan
process at work.
