Mark Liberman: personal info • Faculty in Linguistics, CIS • Co-director (with Kearns) of IRCS • Joined Penn in September 1990 • Previous 15 years in basic research at AT&T Bell Labs • Undergrad at Harvard, PhD at MIT • Research interests: phonetics, prosody, speech technology, computational linguistics, neuroscience • Other activities at Penn: • Director of Linguistic Data Consortium • Faculty Master, Ware College House

  2. More on ML’s research • Tone and intonation in speech • West African languages (Yoruba, Igbo, Mawu) • English • Informational focus and its role in discourse • Syntax, morphology • Intonation • Finding information in masses of text and speech • Multilingual information retrieval • Information extraction from biomedical text • Organization of spoken communication in the brain • In humans and other animals today • In hominid evolution • Agent-based models of language evolution and learning

  3. Phonetics and cognition • Phonetics: the sciences of speech sounds and their relation tolinguistic form and meaning • The interface between signals and symbols • Physics and physiology of speech production and perception • The meanings of speech sounds • as a method for expressing words and sentences • as a medium of expression beyond words, for conveying • individual and group identity • structures of information and interaction • emotion and attitude • Communicating with variable signals in noisy environments • General relations between expectation and observation in perception • Temporally complex actions with many simultaneous goals • “Theory of mind”: acting to affect others’ knowledge/belief/emotion • Learning the sound structure of language
