text: 'In this contribution, a new observation model for the joint compensation
of reverberation and noise in the logarithmic mel power spectral density domain
will be considered. The proposed observation model relates the noisy reverberant
feature to the underlying sequence of clean speech features and the feature of
the noise. Nevertheless, due to the complex interaction of these variables in
the target domain, the observationmodel cannot be applied to Bayesian feature
enhancement directly, calling for approximations that eventually render the observation
model useful. The performance of the approximated observation model will highly
depend on the capability of modeling the difference between the model and the
noisy reverberant observation. A detailed analysis of this observation error will
be provided in this work. Among others, it will point out the need to account
for the instantaneous ratio of the reverberant speech power and the noise power.
