The C-MU phonetic classification system

The Carnegie-Mellon Speech Group is working with a number of institutions in the DARPA community to develop "A New Generation English Language System" (ANGELS) to perform large vocabulary speaker-independent recognition of natural continuous speech. A major focus of this effort is the development of an acoustic-phonetic module that provides an accurate phonetic transcription of an unknown utterance. This paper describes the phonetic classification system now under development, the research approach and some preliminary results.
