hidden Markov modellong memoryquasi-hidden Markov modelIn a hidden Markov model (HMM), the observed data are modelled as a Markov chain plus independent noises, hence loosely speaking, the model has a short memory. In this article, we introduce a broad class of models, quasi-hidden Markov ...
Hidden Markov models (HMM) have been widely used in various applications such as speech processing and bioinformatics. However, the standard hidden Markov model requires state occupancy durations to be geometrically distributed, which can be inappropriate in some real-world applications where the distribu...

Proposes a class of hidden Markov model (HMM) called multiple-regression HMM (MR-HMM) that utilizes auxiliary features such as fundamental frequency (F) and speaking styles that affect spectral parameters to better model the acoustic features of phonemes. Though such auxiliary features are considered...

The hidden Markov model is a kind of Markov chain, and its state cannot be directly observed but can be observed through observation vector sequence; each observation vector is expressed as various states through some probability density distribution, and each observation vector is generated from a ...
