description	Use when deciding what accompanies an INTERSPEECH paper beyond its 4 pages — audio sample pages and multimedia for listening-based judgment, what reviewers may ignore versus must see, the references-and-acknowledgments page's strict scope, and packaging extra analyses when no reviewed appendix exists.

INTERSPEECH Supplementary Material

Interspeech's supplement story is inverted from big-ML venues: there is no reviewed appendix. A regular paper is 4 pages of content plus one page for references and acknowledgments only — everything else is optional accompaniment that reviewers may open but never owe you. Design the paper to stand alone, then design the accompaniment to be irresistible. (Long Papers, new in 2026, follow their own reported 8+2 contract — verify before assuming appendix room.)

The three shelves

Shelf	What lives there	Review status
The 4 pages	Every claim, the decisive table, the assumption set, protocol one-liners	Reviewed; the paper is this
References/acks page	Citations; acknowledgments (camera-ready only)	Policed — nothing else allowed
Accompaniment	Audio demo page, code repo, extended tables, media attachments	Optional reading; anonymity rules apply

The classic failure: a decisive ablation "in the demo page" that a reviewer never opens, followed by a review saying the claim is unsupported. If the paper's fate depends on it, it goes in the 4 pages — compression is the skill (see interspeech-writing-style), not relocation.

Audio: the supplement that actually gets consumed

Interspeech is the one major venue where reviewers routinely listen. For synthesis, conversion, enhancement, and separation papers, the sample page is effectively part of the evidence:

• Curate like an experiment, not a highlight reel: same utterances across systems, including the baseline and the failure cases your error analysis discusses.
• Label conditions exactly as the paper's tables do, so a listener can map sample → table row in seconds.
• Keep it short: reviewers give minutes, not hours. Ten well-chosen triplets beat a hundred files.
• Cherry-picking is detectable and remembered; note explicitly whether samples are random or selected, and match the paper's claim ("randomly drawn from test").
• Anonymity: neutral hosting, clean metadata, no lab-identifiable voices — the full sweep in interspeech-artifact-evaluation applies to every linked byte.

Attachments vs links

Cycles differ on whether media files may be attached in CMT and what the size cap is — check the current author instructions rather than assuming. Attached media is frozen and safely anonymous; linked pages are richer but riskier (identity, mutability). When policy is unclear: attach the minimum decisive audio, link the rest, freeze both.

Extended analyses without an appendix

Where an AISTATS or NeurIPS author would write "App. C", an Interspeech author chooses:

1. Compress into the body — one row, one sentence, one footnote-density claim.
2. Cite the arXiv extended version — but only outside the anonymity period and per the current preprint policy; during review this is usually unavailable.
3. Repo RESULTS.md — full sweeps, per-language tables, negative results; discoverable post-acceptance, invisible to review.
4. Save it for the Long Paper track or a journal extension (TASLP, CSL, Speech Communication) — Interspeech-to-journal extension is a standard community path.

Pick consciously per artifact; the default of "dump everything in the repo" leaves reviewable evidence outside the review.

A sample-page layout that respects reviewer time

Anonymous demo — Paper #1234
Section 1: Main comparison (Table 2 systems, 6 utterances × 4 systems)
  utt-01  [GT] [Baseline] [Ablation] [Proposed]     ← same grid every row
Section 2: Failure cases discussed in Sec 4.3 (3 utterances)
Section 3: Operating points (320/480/640 ms, 2 utterances each)
Selection: utterances drawn randomly from test; seed 17.

The grid mirrors the paper's tables, failure cases are volunteered rather than hidden, and the selection policy is printed on the page itself. A reviewer can audit the audio claims in under five minutes — which is the entire budget you realistically have.

Media-file craft

• Normalize loudness across systems before publishing; a louder system "wins" MOS-by-ear unfairly and reviewers know the trick.
• Same utterance text, same speaker (where applicable), same sample rate across systems — any mismatch invites suspicion of stacked comparisons.
• Keep individual clips short (3–8 s); attention decays per clip, and short clips force you to choose genuinely diagnostic material.
• Provide file-level captions ("proposed, 480 ms, repair-bearing"), never bare audio_final_v2.wav names.

Packaging checklist

[ ] Paper stands alone: no claim depends on unreviewed material
[ ] Sample page: same utterances across systems, failure cases included,
    selection policy stated, mapped to table rows
[ ] Hosting anonymous, page frozen, media metadata scrubbed
[ ] Attachment rules of the current cycle checked (size, formats)
[ ] References page contains references (and, at camera-ready, acks) only
[ ] Extended-material route chosen: body / arXiv-later / repo / journal

Output format

[Shelf audit] what sits on each shelf; anything decisive off-page?
[Audio evidence] curation quality, selection policy, anonymity result
[Attachment plan] attach vs link, per current-cycle rules (cite source)
[Overflow route] compress / arXiv / repo / Long Paper / journal — per item
[Risk] <the unreviewed item most likely to be assumed reviewed>

Current-cycle attachment and preprint rules were checked 2026-07-08 against the Interspeech 2026 author pages via renderings (resources/official-source-map.md); the anonymity-period wording there governs anything you host.
