Senior Applied Scientist Amazon AGI

Byeonggeun Kim

I build models that understand and generate audio for natural, real-time conversations.

My research has progressed from efficient on-device and few-shot audio learning to audio encoders, neural codecs, and generation for Amazon AGI projects, including Amazon Nova. I currently focus on full-duplex speech-to-speech modeling.
