Audio foundation models capture phylogenetic signal without domain-specific training

A new study published on arXiv investigates whether large audio foundation models can capture phylogenetic signals from species vocalizations without explicit training for this purpose. The research found that general-purpose models like CLAP and BEATs-bio demonstrated significant ability to recover phylogenetic distance in marine mammal and bird species, outperforming hand-crafted features. Surprisingly, domain-specific models such as BirdNET did not show superior performance, suggesting that broad pretraining on audio data may be sufficient for encoding evolutionary information. AI

IMPACT Demonstrates that general audio models can encode evolutionary information, potentially impacting bioacoustics research and model development.

    Phylogenetic signal in marine mammal and bird vocalizations captured by audio foundation models: the limited benefit of domain-specific pretraining

    arXiv:2607.22458v1 Announce Type: new Abstract: Do learned audio embeddings encode structure that nobody told them to encode? We probe four large pretrained audio models (AST, CLAP, BEATs-bio and BirdNET) with a downstream task none of them saw during training: recovering phyloge…
