Integrated-multilingual speech recognition using universal phonological features in a functional speech production model

An outline and general design of an integrated-multilingual speech recognizer is presented, focusing on its key novelty of cross-language portability. This recognizer extends the one described in [5] in that the overlapping features designed originally for American English are improved, generalized, and need only a slight expansion to cover Mandarin/Cantonese Chinese and Canadian Rench. It also enhances the recognizer of [6] in that the object of dynamic modeling is moved from the observable acoustic domain to the hidden production-affiliated variables defined in the task-dynamic model of speech production [15]. Major components of the recognizer and the related training and recognition algorithms are described.
