I am a professor at the Department of Computer Science at Bar-Ilan University. My research interests concern both machine learning and computational study of human speech and language. In machine learning my research is focused on deep learning and structured prediction, while my research on speech and language is focused on speech processing, speech recognition, acoustic phonetics, and pathological speech.

My technological goal is to improve the state-of-the-art in applications such as automatic speech recognition, speech indexing and retrieval, acoustic scene analysis, and language understanding. My scientific goal is to contribute to research in human speech communication, phonetics, and medical speech pathology using data-driven methods. I believe that exploiting the structure of language and designing theoretically well-founded statistical machine learning algorithms for particular tasks that are able to make use of large datasets, can solve the complex problems involved in speech and language research. To a great extent, my research interests focus on interdisciplinary areas combining the fields of speech science, machine learning, and linguistics. I therefore constantly collaborate with colleagues from those fields.


Speech, Language and Deep Learning Lab

The research in the lab is focused on statistical and machine learning Topics applied to the modeling and processing of speech and language. A typical problem in speech and language processing has a very large number of training examples, is sequential, highly structured, and has a unique measure of performance. The lab's goal is to develop rigorous statistical and machine learning algorithms that maximize performance by matching the internal structure of the problem and by optimizing its unique measure of performance.

Resources and Code   

The lab is commited to reproducible results. The GitHub repository gives you access to our code, tools and information on how to setup and use. {Deep} Phonetic Tools is a project done in collaboration with Matt Goldrick and Emily Cibelli, where we proposed a set of phonetic tools for measureing VOT, voswel duration, word duration and formants, and are all based on deep learning.
