A hierarchical Dirichlet language model
TL;DR: A hierarchical probabilistic model whose predictions are similar to those of the popular language modelling procedure known as 'smoothing' is discussed, and the methods prove to be about equally accurate, with the hierarchical model using fewer computational resources.

Log-linear interpolation of language models.
TL;DR: This method of log-linear interpolation (LLI) is used for adaptation and for combining models of di erent context length and is better than linear interpolation in both cases.

Use of temporal correlation between successive frames in a hidden Markov model based speech recognizer
TL;DR: The temporal correlation between successive frames is incorporated in an HMM (hidden Markov model) based speech recognizer and preliminary results show that this approach provides significant improvement in recognition performance.
Journal ArticleDOI
A comparison of novel techniques for rapid speaker adaptation
TL;DR: An adaptation technique called speaker cluster weighting (SCW) which provides a means for improving upon generic hierarchical speaker clustering techniques and a word error rate reduction of 20% has been achieved from the baseline speaker independent (SI) recognition system.

A study of n -gram and decision tree letter language modeling methods
TL;DR: It is concluded that the bottom-up deleted interpolation algorithm performs the best in the task of n -gram letter language model smoothing, significantly outperforming the back-off smoothing technique for large values of n .
