Pmtools : A pronunciation modeling toolkit.
Richard Sproat · 2001
This paper reports on a pronunciation modeling toolkit --- pmtools --- that allows one to train a weighted finite-state transducer using a Classification and Regression Tree (CART) training paradigm. Tools are provided to automatically align a pronunciation dictionary consisting of a set of words and their pronunciations, train a set of CART trees on the aligned dictionary, and compile those trees out into a special class of weighted finitestate transducer. Most of the complexity --- aligning the data, labeling the data with features, and training the trees --- is hidden from the user. While
