PairAlign: A Framework for Sequence Tokenization via Self-Alignment with Applications to Audio Tokenization

Adhiraj Banerjee, Vipul Arora

PairAlign generates compact audio token sequences by training each view's output to be likely under the other's encoder while contrasting unrelated examples.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

On TIMIT retrieval, it preserves edit-distance search while reducing archive token count by 55%. A continuous-sweep probe shows lower local overlap than a dense geometric tokenizer, but stronger length control and bounded edit trajectories under 100 ms shifts.

C2weakest assumption

That optimizing cross-view sequence likelihood with unrelated negatives as contrast produces token sequences whose edit-distance properties generalize to downstream tasks without direct supervision on those properties.

C3one line summary

PairAlign learns compact audio token sequences via self-alignment of paired content views using an autoregressive decoder, achieving strong cross-view consistency and edit-distance preservation while reducing token count by 55% on TIMIT.
