How Well Do Self-Supervised Speech Models Encode Age and Gender in Children's Speech? A Layer-Wise Analysis Across Multiple Architectures

Researchers conducted a comprehensive layer-wise analysis of how four major self-supervised learning (SSL) speech models encode age and gender information in children's speech. The study reveals that age and gender cues are unevenly distributed across model layers, with early-to-mid layers capturing the strongest paralinguistic signals, and demonstrates reliable classification accuracy even from 1-3 second audio segments.

A Layer-wise Analysis of Supervised Fine-Tuning

Researchers present a layer-wise analysis of Supervised Fine-Tuning (SFT) in large language models, revealing that middle layers remain stable during training while final layers exhibit high sensitivity. They introduce Mid-Block Efficient Tuning, a targeted approach that selectively updates intermediate layers and achieves up to 10.2% performance gains over standard LoRA on benchmarks with significantly reduced parameter overhead.
