Original Abstract

This paper describes the difficulties associated with soft R-FMLLR. By analyzing the Jacobian matrix, it was concludedthat the transformation is most likely to be non-invertibleand in this case ML estimation adversely affects the performance.A new transformation, hard R-FMLLR, is presented. Itis shown that the performance of the proposed method is betterthan soft R-FMLLR and it is computationally more efficient.
