Computer Science
Julia B. Hirschberg studies the prosody—intonation and melody—of speech, with the goal of teaching computers to understand subtle variations and reproduce them in natural-sounding speech. This involves understanding how prosody changes under different circumstances. Hirschberg established Columbia’s Spoken Language Processing Group.
Hirschberg has analyzed the prosody of charismatic and deceptive speech and developed a computer system that is more successful than humans at detecting lies. She studies entrainment— the tendency of people to mirror back the spoken mannerisms of those who are speaking to them—in voice-response systems. Hirschberg also does research on emotional speech, code-switching, and text-to-speech synthesis.
