Nonparametric Bayesian Double Articulation Analyzer

This is a Python implementation for Nonparametric Bayesian Double Articulation Analyzer (NPB-DAA). The NPB-DAA can directly acquire language and acoustic models from observed continuous speech signals.

This generative model is called hiererichel Dirichlet process hidden language model (HDP-HLM), which is obtained by extending the hierarchical Dirichlet process hidden semi-Markov model (HDP-HSMM) proposed by Johnson et al. An inference procedure for the HDP-HLM is derived using the blocked Gibbs sampler originally proposed for the HDP-HSMM.

Description

・NPB_DAA/README - There is a NPB-DAA tutorial in PDF.(In Japanese. English version is coming soon.)

・NPB_DAA/pyhsmm - Python Library for HDP-HSMM. You can get it at [ https://github.com/mattjj/pyhsmm ]. (Please check this VERSION at README)

・NPB_DAA/dahsmm - Python code for NPB-DAA
