This paper presents a new parameter estimation algorithm
based on the Extended Kalman Filter (EKF) for the recently
proposed statistical coarticulatory Hidden Dynamic
Model (HDM).We show how the EKF parameter estimation
algorithm unifies and simplifies the estimation of both the
state and parameter vectors. Experiments based on N-best
rescoring demonstrate superior performance of the (contextindependent)
HDM over a triphone baseline HMM in the
TIMIT phonetic recognition task. We also show that the
HDM is capable of generating speech vectors close to those
from the corresponding real data.
