Towards Data-free and Training-free Compression for Speech Foundation Models Using Parameter Clustering

Researchers present a novel compression technique for speech foundation models using parameter clustering and k-means pruning without requiring training data or fine-tuning. The method demonstrates significant performance improvements over traditional magnitude-based pruning on HuBERT-large and Whisper-large-v3, with 27-59% relative WER reductions at various sparsity levels.

Pretrained self-supervised speech models can recognize unseen consonants

Researchers demonstrate that pretrained self-supervised speech models (Wav2Vec2 and HuBERT) can accurately recognize click consonants from low-resource Khoisan languages despite training data heavily skewed toward high-resource languages. Fine-tuning on click-rich language data reveals these models generalize better to rare phonemes than expected, suggesting self-supervision creates robust representations across diverse human speech sounds.

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.

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.
