    Talk Title: Weighted Finite-State Transducers: The Later Years

    Series: NL Seminar

    Abstract: REMINDER
    Meeting hosts only admit guests that they know to the Zoom meeting. Hence, you are highly encouraged to use your USC account to sign into Zoom.

    If you are an outside visitor, please inform us at (nlg DASH seminar DASH host AT isi DOR edu beforehand so we will be aware of your attendance and let you in.

    In-person attendance will be permitted for USC ISI faculty, staff, students only. Open to the public virtually via the zoom registration link and online.

    While the deep learning tsunami defines the state of the art in speech and language processing, finite state transducer grammars developed by linguists and engineers are still widely used in highly multilingual settings, particularly for front end speech applications. In this talk, I will first briefly review the current state of the OpenFst and OpenGrm finite state transducer libraries. I will then discuss several recent innovations in the finite state world. These include algorithms for inducing text normalization and grapheme to phoneme grammars from parallel data, heuristic optimization of arbitrary weighted transducers, and an algorithm for efficiently computing the single shortest string of a wider variety of non deterministic weighted acceptors.

    Biography: Kyle Gorman is an assistant professor of linguistics at the Graduate Center, City University of New York, and director of the masters program in computational linguistics. He is also a software engineer in the speech and language algorithms group at Google. With Richard Sproat, he is the coauthor of Finite State Text Processing and the creator of Pynini, a finite state text processing library for Python. He has also published on statistical methods for comparing computational models, text normalization, grapheme to phoneme conversion, and morphological analysis, as well as many topics in linguistic theory.
