Sequence-Level Vocal Convergence in Common Marmosets

A primate project using sequence-comparison methods to test whether dyads converge on shared vocal structure.

Core Question

Do social partners converge not only in the sound of individual calls, but also in the larger sequence structure of their vocal exchanges?

Approach

This work develops a sequence-comparison framework inspired by bioinformatics-style alignment, then combines it with note-level spectral measurements to test for multiple layers of vocal accommodation.

What Emerged

The project points to separable forms of encoding: individual identity in spectral call features and dyad identity in sequence-level structure.

Broader Goal

The larger ambition is to move beyond single-call analysis and treat vocal sequences as structured social behaviour in their own right.
