Direct Answer
speakable is a Schema.org property within WebPage that flags which sections of a page are best read aloud by voice assistants like Google Assistant. It uses cssSelector to point to specific elements (typically the H1 and a 30-word direct-answer paragraph). It is a key building block for voice-search optimization.
Voice answer (≤30 words)
“Speakable is schema markup that flags which parts of a page work for voice assistants. Use it on the H1 and a thirty-word answer.”
Voice answers should be ≤30 words, conversational, jargon-free, and start with the answer rather than a setup.
Add data-speakable attributes to the same elements you reference in the cssSelector — both signals together raise extraction odds.
