Biography

Mark Yoffe Liberman’s trailblazing efforts in creating the Linguistic Data Consortium (LDC) have fueled the development and advancement of human language technologies (HLTs) including speech and speaker recognition, machine translation, and semantic analyses. Founded at the University of Pennsylvania in 1992, the LDC became the largest developer of shared language resources, distributing more than 120,000 copies of over 2,000 databases covering 91 different languages to more than 3,600 organizations in over 70 countries. Liberman has also helped to create technologies that have daily impact on HLTs, including a speech activity detector that regularly processes LDC speech data to reduce annotation cost and increase accuracy and a forced aligner that was integrated into the Forced Alignment and Vowel Extraction service that has revolutionized phonetic and sociolinguistic research.

Liberman is the Christopher H. Browne Distinguished Professor of Linguistics and director of the Linguistic Data Consortium at the University of Pennsylvania, Philadelphia, PA, USA.
