An exemplary method for generating speech based on text in one or more languages includes providing a phone set for two or more languages, training multilingual HMMs where the HMMs include state level sharing across languages, receiving text in one or more of the languages of the multilingual HMMs and generating speech, for the received text, based at least in part on the multilingual HMMs. Other exemplary techniques include mapping between a decision tree for a first language and a decision tree for a second language, and optionally vice versa, and Kullback-Leibler divergence analysis for a multilingual text-to-speech system.
