Liberman is the son of the psychologists Alvin Liberman and Isabelle Liberman, both of whom are now deceased.

Liberman attended Harvard College but did not graduate. After two years' service in the US Army in Vietnam, he enrolled in graduate school in linguistics at MIT where he received his MA and, in 1975, his PhD.

From 1975 to 1990, he was a Member of Technical Staff at Bell Laboratories.

Liberman's main research interests lie in phonetics, prosody, and other aspects of speech communication. His early research established the linguistic subfield of metrical phonology. Much of his current research is conducted through computational analyses of linguistic corpora.
