Liberman's research interests include corpus-based phonetics, speech and language technology, computational linguistics, phonology and phonetics of lexical tone and its relationship to intonation, formal models for linguistic annotation, and clinical applications of linguistic analysis.

Liberman is a Fellow of the Linguistic Society of America and the American Association for the Advancement of Science. He has received the Linguistic Society of America's Linguistics, Language and the Public Award in 2009 for Language Log, the Antonio Zampolli Prize from the European Language Resources Association in 2010, and the IEEE James L.
