About me

This is Pengjie Shen’s homepage. I am a Ph.D. student in Computer Science and Technology at Inner Mongolia University, focusing on speech signal processing. My research spans several closely related areas:

  • Speech Separation – designing algorithms that disentangle overlapping speakers in noisy or reverberant environments
  • Speech Enhancement – improving intelligibility and perceptual quality for both human listeners and downstream ASR systems
  • Target Speaker Extraction – isolating a desired voice from multi‑speaker mixtures using limited enrollment data
  • Multi‑Channel Microphone Array Processing – leveraging spatial cues and beamforming strategies to boost robustness under real‑world acoustic conditions
