Several successful approaches to speech recognition have been proposed
. Most of them involve time alignment which requires substantial compu
tation and considerable memory storage. In this paper, we present a ne
uro-fuzzy approach to speech recognition without time alignment. This
approach is a powerful method for selecting reference templates; there
fore, considerable memory storage is alleviated. In addition, it great
ly reduces substantial computation in the matching process because it
obviates time alignment. Base on this approach, a Mandarin speech reco
gnition system without time alignment is implemented. Two databases we
re utilized for verifying its performance. An encouraging experimental
result confirms the effectiveness of the proposed neuro-fuzzy approac
h to speech recognition without time alignment. (C) 1998 Elsevier Scie
