Abstract:
|
Modelling varying speaking style remains a challenge to sta
te
of the art speech recognition and synthesis systems. Vowel a
nd consonant
reduction have been identified as correlative to speaking st
yle variation,
but still lack a common measurement. The reduction phenomen
aare
often observed without consideration of coarticulation an
dassimilation
e
!
ects, and as a result of speaking rate variability. We present an analy-
sis of acoustic reduction in Mel Frequency cepstral coe
"
cie
nts (MFCC)
feature space of phonemes, estimate duration and determine
the degree
of correlation between duration reduction and feature spac
ereduction
for two di
!
erent speaking styles present in broadcast news a
nd conversa-
tional recordings. We analyse the feature space reduction o
fconsonants
and vowels in context in a syllable environment |
