  abstract     = {{In this paper, it is shown that a correlation criterion is the appropriate criterion for bottom-up clustering to obtain broad phonetic class regression trees for maximum likelihood linear regression (MLLR)-based speaker adaptation. The correlation structure among speech units is estimated on the speaker-independent training data. In adaptation experiments the tree outperformed a regression tree obtained from clustering according to closeness in acoustic space and achieved results comparable with those of a manually designed broad phonetic class tree}},

@article{32503,
  abstract     = {{Two parameters of language production, the partner model and the mentally represented knowledge
about a spatial constellation, are investigated with respect to their influence on spatial reference. At
issue is whether the verbally expressed point of view in route directions is primarily influenced by the
needs of the partner or by the underlying mental representation of the speaker stemming from his or
her own experience with an object. Two experiments in which participants (N 5 90) were asked to
produce a set of route directions are reported. The experimental situation was such that the point of
view of the speaker did not correspond to the point of view of the partner. The results show that more
participants localize from their own point of view than from the point of view of the partner.
Discussion centers on the fact that speakers do not always behave in a truly partner-oriented manner.}},
