Self-supervised speech models exhibit phonological vector arithmetic

By PulseAugur Editorial · [1 sources] ·

Researchers have discovered that self-supervised speech models (S3Ms) encode phonological features in a structured, compositional manner. A study across 96 languages revealed linear directions within S3M representations that correspond to phonological features, with the scale of these vectors correlating to their acoustic realization. This indicates that S3Ms utilize phonologically interpretable vectors, enabling "phonological vector arithmetic" where operations like adding a voicing vector can transform sounds, such as changing [p] to [b].

IMPACT Reveals a deeper understanding of how speech models process linguistic information, potentially improving future speech synthesis and recognition systems.

    [b] = [d] - [t] + [p]: Self-supervised Speech Models Discover Phonological Vector Arithmetic

    arXiv:2602.18899v4 Announce Type: replace-cross Abstract: Self-supervised speech models (S3Ms) are known to encode rich phonetic information, yet how this information is structured remains underexplored. We conduct a comprehensive study across 96 languages to analyze the underlyi…
