Dysfluency-Friendly Mode — origin note¶

Written: 2026-06-19 · Owner: Mohsen Seyedkazemi Ardebili Shipped as: ADR-015 — Dysfluency-Friendly Mode Tier: design/ — public. Historical origin note; the ADR above is the current source of truth.

The idea¶

The pitch: a dictation tool that silently punishes a person for how they speak — cutting off a stutterer's block mid-word because the endpointer mistook the silent struggle for "done," or transcribing the literal repetitions instead of the sentence the speaker meant — is solving the wrong problem. The claim, stated as a real bet rather than a hope, was that most of the fix is available today with no acoustic model retraining at all: a more forgiving endpointer so blocks and pauses don't truncate the utterance, plus a post-processing pass that collapses repetitions, prolongations, and blocks into the intended words, guarded so it never strips a speaker's intentional repetition.

What shipped¶

The collapse pass shipped as stt/filters/disfluency.py's three-pass filter (filler removal → 2-gram dedup → self-correction rollback), wired under the dysfluency feature toggle and folded into YazSes's accessibility preset (RECOMMENDED tier, not experimental). It runs offline, on a consumer CPU, with no model training — exactly the constraint the original card set for itself.
