Candy Olivia Mawalim

Senior Lecturer, JAIST, Japan

Hi, I'm Candy! I am a senior lecturer at School of Information Science, Japan Advanced Institute of Science and Technology (JAIST). My primary research interests are speech signal processing, machine learning, and social signal processing (SSP). My Ph.D. thesis focuses on privacy preservation and secure speech communication. In addition to primary research, I also carried out a research project on personality traits and communication skills modeling with Prof. Shogo Okada. I obtained my Ph.D. and M.S. degrees in Information Science, JAIST, advised by Prof. Masashi Unoki.

Research interests: speech information hiding, voice privacy, social signal processing, and machine learning.

It was an honor to speak at the University of Zurich's Phonetics Lunch Meeting. I presented on the challenges of multilingual speech deepfake detection. Great to see such an active and engaged research group!

OCT 22-24, 2025

I had a great time at The APSIPA ASC in Shangri-la, Singapore. It was a proud moment seeing two of our students (Mr. Nopparut Li and Ms. Junia Denawati) present their work. I was also honored to serve as a Session Chair for the Signal and Information Processing session.

OCT 12-15, 2025

Just wrapped up a great experience at The IEEE Workshop on Applications of Signal Processing to Audio and Acoustics (WASPAA) 2025 in Granlibakken Tahoe, CA! I presented our paper, "Modeling Multi-Level Hearing Loss for Speech Intelligibility Prediction." The conference was fantastic—the single-session format made it easy to learn a lot and connect with everyone.

We had a productive time at the 6th Clarity Workshop on Improving Speech-in-Noise for Hearing Devices (Clarity-2025) in TU Delft, The Netherlands. We were excited to present our papers through both poster and oral presentations, sharing our work in improving speech intelligibility prediction for hearing devices. Our team also participated in the 3rd Clarity Prediction Challenge (CPC3), where we were proud to secure the 4th rank. It was inspiring to see so many innovative ideas from other participants on how to advance intelligibility prediction for hearing aid development. The talks on hearing aid speech enhancement were also incredibly insightful.

AUG 17-21, 2025

I had a great experience attending the Interspeech 2025 in Rotterdam, The Netherlands. It was a privilege to engage with the latest research and network with so many talented people in the field. I'm leaving inspired and ready to apply what I've learned.
