   A Time Delay Radial Basis Function Network for Phoneme Recognition
                           Michael R. Berthold

ABSTRACT:
This paper presents the Time Delay Radial Basis Function Network  (TDRBF)
for recognition of phonemes.  The TDRBF combines features from Time Delay
Neural Networks (TDNN)  and Radial Basis Functions (RBF).  The ability to
detect acoustic features and their  temporal relationship  independent of
position in time is inherited from TDNN. The use of RBFs leads to shorter
training times and  less parameters  to adjust,  which makes it easier to
apply TDRBF to new tasks.
The recognition of  three phonemes  with about  750 training  and testing
tokens each  was choosen  as an  evaluation task.  The results suggest an
equivalent performance of TDRBF and TDNN presented by Waibel et al.,  but
TDRBF require much less  training time to reach a good performance and in
addition have  a  clear  indication  when  the  minimum error is reached,
therefore no danger of overtraining exists.
