Automated Pronunciation Evaluation for Korean Toddler Speech using Speech Diarization and Self-Supervised Learning

Researchers have developed an automated system for evaluating Korean toddler pronunciation using speaker diarization and self-supervised learning models, addressing a significant gap in speech assessment tools for this demographic. The system achieved balanced accuracies of 0.720 for consonants and 0.845 for vowels by routing predictions through specialized SSL models, offering potential clinical applications for detecting speech sound disorders affecting nearly half of Korean pediatric cases.

What Do Deepfake Speech Detectors Actually Hear?

Researchers developed an explainability pipeline that reveals what deepfake speech detectors actually focus on when identifying synthetic audio. The study found that three leading WavLM-based detectors rely on fundamentally different cues—environmental artifacts, phoneme distortions, and spectral patterns—despite achieving similar accuracy levels, with findings validated through causal masking experiments.

Do Compact SSL Backbones Matter for Audio Deepfake Detection? A Controlled Study with RAPTOR

Researchers introduced RAPTOR, a study comparing compact SSL models for audio deepfake detection, finding that multilingual HuBERT pre-training enables smaller 100M parameter models to match larger commercial systems. The study reveals that pre-training approach matters more than model size, with WavLM variants showing overconfident miscalibration issues compared to HuBERT models.
