暫定日本語訳:Speakable schema (schema.org's SpeakableSpecification, 追加 via speakable プロパティ on 記事 または WebPage) marks 2–3 sentences on ページ best suited へ be read aloud by text-へ-speech — ない whole 記事. あなた point at them とともに one locator 方法, cssSelector または xPath, 決して both. single 大半の 重要 thing へ know in 2026: it's still explicitly BETA (as it has been since July 2018), still limited へ US, English, Google Home ユーザー, と Google has ない connected it へ AI Overviews または AI Mode despite dozens of SEO posts claiming it 現在 signals citation-worthy passages. It wasn't deprecated in Google's January 2026 cleanup と wasn't mentioned at I/O 2026 — ただし Google Assistant it was built へ フィード is being replaced by Gemini 向けに Home, と nobody, Google 含む, has said whether Gemini 向けに Home still reads Speakable markup. Treat it as dormant と news-publisher-narrow, ない dead — と ない AI-検索 lever.

Evidence for this claim Schema.org defines speakable as a property whose value can be a SpeakableSpecification identifying sections suitable for text-to-speech. Scope: Schema.org vocabulary semantics. Confidence: high · Verified: Schema.org: speakable Evidence for this claim Google documents speakable structured data as a beta feature with limited language, region, device, and publisher eligibility. Scope: Current documented Google feature eligibility; no documented connection to AI Overviews. Confidence: high · Verified: Google Search Central: Speakable

暫定日本語案: TL;DR — Speakable is speakable プロパティ (value: SpeakableSpecification 暫定日本語案: object) on Article/WebPage — ない standalone type. It marks 2–3 暫定日本語案: sentences (~20–30s) best read aloud by TTS, located by one of cssSelector 暫定日本語案: または xPath. It’s been explicitly BETA since July 2018 と, per doc updated 暫定日本語案: December 2025, is still limited へ US, English, Google Home ユーザー. It 暫定日本語案: survived Google’s January 2026 structured-データ cleanup と wasn’t mentioned at 暫定日本語案: I/O 2026 — so it’s dormant, ない deprecated. Two accuracy spines: (1) no 暫定日本語案: Google-公式 ソース connects Speakable へ AI Overviews / AI Mode — その’s 暫定日本語案: repeated-ただし-unsourced 2026 myth; と (2) Google Assistant it フィード is being 暫定日本語案: replaced by Gemini 向けに Home, と nobody has said whether Gemini 向けに Home still 暫定日本語案: consumes Speakable. Treat it as US-news-publisher relic, ない AI-検索 lever.

何 Speakable actually is

暫定日本語案: Google’s framing is precise: “The speakable property identifies sections within an article or webpage that are best suited for audio playback using text-to-speech (TTS).” (Google 検索 Central) 暫定日本語案: 重要 structural point: it is ない its own schema type. It’s 暫定日本語案: speakable プロパティ, whose value is SpeakableSpecification object, と あなた 暫定日本語案: attach it へ Article または WebPage ( NewsArticle 機能 too, by schema.org 暫定日本語案: inheritance から Article).

暫定日本語案: と あなた don’t mark up whole ページ. あなた point at 2–3 sentences — 暫定日本語案: headline と concise summary — その stand on their own いつ read out of visual 暫定日本語案: context へ listener. その “sections, not the whole article” distinction is 暫定日本語案: entire design intent.

Locating speakable コンテンツ: cssSelector vs xPath

暫定日本語案: あなた pick exactly one of two locator 方法 — 決して both on 同じ markup:

  • 暫定日本語案: cssSelector“Addresses content in the annotated pages (such as class attribute).” あなた target elements by class または CSS path (e.g. .headline, 暫定日本語案: .summary).
  • 暫定日本語案: xPath“Addresses content using xPaths (assuming an XML view of the content).” あなた target elements by their XPath (e.g. /html/head/title).

暫定日本語案: cssSelector is more maintainable choice 向けに 大半の サイト because it survives 暫定日本語案: markup reshuffles better than brittle absolute XPath — ただし both are 有効.

暫定日本語案: One spelling gotcha worth knowing 前に あなた copy 例 から 誤った place: 暫定日本語案: schema.org’s own vocabulary ページ spells underlying プロパティ lowercase, 暫定日本語案: xpath, while Google’s Speakable doc と すべての JSON-LD 例 on it 使用 暫定日本語案: camelCase, xPath. Since it’s Google Assistant consuming この markup, follow 暫定日本語案: Google’s xPath casing in あなた JSON-LD — schema.org ページ defines broader 暫定日本語案: vocabulary, ない プロパティ name Google’s parser expects.

コンテンツ guidelines その still hold up

暫定日本語案: Even outside Speakable’s own 適格性, its コンテンツ rules are good TTS advice:

  • 暫定日本語案: Length. Google: “For optimal audio user experiences, we recommend around 20-30 seconds of content per section of speakable structured data, or roughly two to three sentences.” (Google 検索 Central)
  • 暫定日本語案: 避ける context-dependent text. Google: “Don’t add speakable structured data to content that may sound confusing in voice-only and voice-forward situations, like datelines (location where the story was reported), photo captions, or source attributions.” (Google 検索 Central)
  • 暫定日本語案: Write concise, self-contained summaries. Google: “Content indicated by speakable structured data must have concise headlines and/or summaries that provide users with comprehensible and useful information.” (Google 検索 Central)

Who できる actually 使用 it — still narrow in 2026

暫定日本語案: Here’s どこ honesty matters. feature is still explicitly BETA — Google: 暫定日本語案: “This feature is in beta and subject to change.” (Google 検索 Central) 暫定日本語案: その’s ない stale doc I’m quoting: ページ footer reads “Last updated 2025-12-10 UTC,” so Google is still touching it — it just hasn’t changed scope.

暫定日本語案: と scope is exactly 何 it was at 2018 launch. Google: “The speakable property works for users in the U.S. that have Google Home devices set to English, and publishers that publish content in English.” (Google 検索 Central) 暫定日本語案: Google adds it hopes へ launch in other countries と 言語 “as soon as sufficient number of publishers have implemented speakable — promise 最初 暫定日本語案: made in 2018 その, as of December 2025 doc, is still unfulfilled seven-plus 暫定日本語案: years later. いつ I see “we hope to expand soon” line その has sat unchanged 向けに 暫定日本語案: seven years, I read it as promise その quietly expired, ない roadmap.

暫定日本語案: その US/English/Google Home line is だけ half 適格性 bar. doc’s own 暫定日本語案: “Getting started” section states other half directly: “For your news content to be eligible as answers to topical news queries, follow these steps.” 暫定日本語案: (Google 検索 Central) 暫定日本語案: News コンテンツ isn’t genre I’m inferring から context — it’s explicit subject 暫定日本語案: of section その tells あなた どのように へ become 適格.

暫定日本語案: 何 it フィード is equally specific: “The Google Assistant uses speakable structured data to answer topical news queries on smart speaker devices.” (Google 検索 Central) 暫定日本語案: Note 何 その is ない: it 決して produced visible SERP rich result way 暫定日本語案: Review stars または Breadcrumbs did. Its entire output surface was audio on Google 暫定日本語案: Home device.

Is it dead? No — ただし read signals carefully

暫定日本語案: Three checkable facts, none of which say “deprecated”:

  • 暫定日本語案: It survived January 2026 cleanup. Google’s late-2025/early-2026 暫定日本語案: structured-データ pruning 削除 support 向けに batch of rich-result types 暫定日本語案: (検索エンジン Land coverage). 暫定日本語案: Speakable was ない on その list — neither killed nor reaffirmed. Just untouched.
  • 暫定日本語案: It wasn’t mentioned at I/O 2026. I went 通じて Google’s 暫定日本語案: I/O 2026 検索 recap 暫定日本語案: と roundups — no Speakable mention in any 検索 announcement. Consistent 暫定日本語案: とともに feature Google maintains ただし no longer promotes.
  • 暫定日本語案: Adoption is real ただし tiny. schema.org’s SpeakableSpecification ページ 暫定日本語案: レポート usage in “100K–1M domains” band (attributed へ Google, 可能性がある 2026) — 暫定日本語案: genuine adoption, ただし rounding error next へ Article- または Organization-scale 暫定日本語案: types.

暫定日本語案: None of それらの three facts is Google statement について Speakable’s lifecycle — 暫定日本語案: Google hasn’t called it dormant, active, または anything else. “Dormant and narrow” is 暫定日本語案: my read of pattern それらの facts form, ない something Google has confirmed either 暫定日本語案: way. So: dormant と narrow is my inference から その pattern; deprecated is 暫定日本語案: ない — Google hasn’t said either. John Mueller’s framing 暫定日本語案: during January 2026 removals discussion is right lens 向けに all schema of この 暫定日本語案: kind — “Understand that markup types come and go, but a precious few you should hold on to (like title, and meta robots).” (検索エンジン Roundtable) 暫定日本語案: Speakable is squarely in “come and go” bucket, ない “hold on to” one. 暫定日本語案: Mueller’s Reddit remark is relayed via 検索エンジン Roundtable; original 暫定日本語案: ページ blocked direct verification この session, so treat it as 二次-sourced.

elephant in room: Assistant → Gemini 向けに Home

暫定日本語案: Here’s genuinely 現在の, 下で-covered part. Speakable’s entire consumer is 暫定日本語案: Google Assistant reading news on Google Home. と throughout 2026 Google is 暫定日本語案: replacing Google Assistant とともに Gemini 向けに Home — 最初 purpose-built 暫定日本語案: device, Google Home Speaker, shipped in June 2026, 暫定日本語案: と Gemini 向けに Home is expanding へ more third-party speakers この year.

暫定日本語案: 現在 connect dots: no ソース — ない Google’s Speakable doc, ない Gemini 向けに 暫定日本語案: Home launch material, ない any SEO commentary I できる find — says whether Gemini 向けに 暫定日本語案: Home still consumes Speakable markup way Assistant did. doc talks 暫定日本語案: について “the Google Assistant”; Assistant is being sunset; と two ページ 暫定日本語案: 決して mention 各 other. その’s ない me predicting doom — it’s open, unresolved 暫定日本語案: status question その I’d treat as single biggest 理由 へ be cautious here. 暫定日本語案: Frame it as open question, ない fact in either direction.

Does Speakable 役立つ とともに AI Overviews または AI Mode? ない documented lever

暫定日本語案: この is other accuracy spine, と it’s どこ lot of 2026 コンテンツ is simply 暫定日本語案: 誤った. wave of “GEO”/AI-検索 posts assert その Speakable 現在 signals 暫定日本語案: “citation-worthy passages” へ AI Overviews または AI Mode. No Google-公式 ソース 暫定日本語案: supports その. Google’s own AI-features doc is direct について general point: 暫定日本語案: “There’s also no special schema.org structured data that you need to add” へ 暫定日本語案: 表示される in AI Overviews または AI Mode. (Google 検索 Central) 暫定日本語案: その’s Google ruling out “special markup” requirement in general — it isn’t 暫定日本語案: Speakable-specific statement, so I’m careful ない へ stretch it へ “Google says Speakable has zero effect.” one industry analysis その 確認 暫定日本語案: Speakable-specific claim (SEO Strategy Ltd, Sept 2025) 暫定日本語案: states it plainly: “Speakable does not influence AI Overviews. Google does not use speakable selectors when deciding what to include in its AI-generated summaries.” 暫定日本語案: Absence of ドキュメント isn’t proof of zero effect — ただし there’s また no evidence 暫定日本語案: of positive one, と honest label is “not a documented lever or requirement,” 暫定日本語案: ない hedge-無料 “it does nothing.” 暫定日本語案: SEO Strategy Ltd is industry analysis, ない Google statement — ただし it’s 暫定日本語案: one ソース その directly テスト claim rather than repeating it.

暫定日本語案: broader evidence points 同じ way. Ahrefs 暫定日本語案: tracked 1 885 ページ adding schema 暫定日本語案: (JSON-LD 追加 Aug 2025–Mar 2026, 測定 against AI Overviews, AI Mode, と 暫定日本語案: ChatGPT citations) と found no meaningful citation uplift から adding schema 暫定日本語案: broadly. その study isn’t Speakable-specific, ただし it’s directly relevant へ 暫定日本語案: “add Speakable and get cited by AI” pitch: general lever それらの posts assume 暫定日本語案: doesn’t 表示 up in データ. If あなた’ve read structured-データ hub, この is 暫定日本語案: 同じ story as すべての other “schema for AI citations” claim — schema is entity 暫定日本語案: infrastructure, ない citation cheat code.

すべき あなた implement it in 2026

  • 暫定日本語案: Maybe worth it: あなた’re US, English-言語 news publisher already 暫定日本語案: invested in Google Home audio, marginal cost is low, と あなた want へ cover 暫定日本語案: one narrow surface it フィード. Even then, weigh Gemini-向けに-Home uncertainty.
  • 暫定日本語案: Very likely wasted effort: あなた’re outside US/English, あなた’re ない news 暫定日本語案: publisher, または — 大半の commonly — あなた’re adding it because listicle told あなた it 暫定日本語案: 役立つ AI 検索. It doesn’t. Spend その effort on Organization/Person entity 暫定日本語案: markup とともに 正しい sameAs values instead, which is schema その actually 暫定日本語案: 役立つ machines resolve who あなた are.

どこ この sits

暫定日本語案: Speakable belongs へ 同じ practitioner grouping as ページ-level metadata-trust 暫定日本語案: markup — type whose one flagship 使用 ケース (here, Google Home news readback) went 暫定日本語案: quiet while underlying schema.org type itself was 決して deprecated. It’s 暫定日本語案: sibling deep-dive off Structured データ 向けに SEO 暫定日本語案: hub, alongside schema markup, JSON-LD, と rich results. Like Webサイト/sitelinks- 暫定日本語案: searchbox pattern, it’s useful ケース study in reading schema type honestly: ない 暫定日本語案: dead, ただし ない thing hype says it is.
