Spoken Language Processing Group
The Spoken Language Processing Group at Columbia, which was established by Prof. Julia Hirschberg, includes PhD, masters, and undergraduate students and postdocs. We have done research on emotion and sentiment, deception, charisma, trust and mistrust, humor and sarcasm, misinformation and disinformation, radicalization, and empathy in speech, text, and video, as well as hateful and abusive speech, code-switching, dialogue systems, andr text-to-speech synthesis in English and Low-Resource Languages.
We have collaborated with other members of the Columbia NLP Group and have worked with faculty in other disciplines, including journalism, English, and history. We also have research partnerships with other universities and research labs and enjoy funding from NSF, DARPA, and AFOSR.
We have a laboratory in Schapiro CEPSR 7LW3,
where we perform laboratory studies on human speech production, analyze
speech, and build speech technologies.
