SLP-RL

SPL Research Lab

The School of Computer Science and Engeenering
The Hebrew University of Jerusalem

The Spoken Language Processing Research Lab (SLP-RL), led by Dr. Yossi Adi at The Hebrew University of Jerusalem, is a dynamic hub for cutting-edge research. Our diverse research interests span spoken language modeling, automatic speech recognition, speech enhancement, speech and audio generation, and machine learning for audio, speech, and language processing.

Our lab collaborates with the global research community to advance speech technology through machine learning and deep learning toolks. Our goal is to create adaptive systems that enrich spoken human communication across various languages.

If you would like to pursue graduate studies with us (Master or PhD), please send your CV, research interests, and example code projects to the following address: yossi.adi@mail.huji.ac.il.

Textless NLP

In TextlessNLP, our goal is to build large language models that can directly process audio inputs, without accessing any textual supervision. Being able to achieve that would benefit languages that do not have large textual resources or standard orthography. It would also benefit high-resource languages where: (i) the oral and written forms often mismatch; (ii) linguistically relevant signals are absent from text (e.g., intonation)

Audio Research

The SLP Research Lab is actively involved in conducting research and advancing neural architectures to address various fundamental challenges in the domain of audio processing. This encompasses a wide range of tasks, including background noise removal, artificial bandwidth-extension (a.k.a audio super-resolution), audio compression, voice conversion, etc. For additional details, please refer to the publication section.

Hebrew Speech Technologies

Speech technology has made much progress over the past decade and has been integrated into many consumer products. Despite the progress, most of the models were developed for English and other high-resource languages. In this project, our goal is to build speech technologies (automatic-speech-recognition and text-to-speech) for the Hebrew language together with constructing a large scale Hebrew dataset.
