Short definition
Speakable is a schema.org property that marks specific sections of a page as suitable for text-to-speech reading by voice assistants.
In depth
Speakable schema is a SpeakableSpecification embedded in a webpage's JSON-LD that points (via CSS selectors or xpath) at the sentences best suited for voice reading. Currently most useful for news sites and FAQ pages, it signals intent to engines that handle voice and is increasingly relevant for AI assistants generating spoken answers. Pairs naturally with FAQPage schema and concise summary paragraphs.
Example
A med spa adds speakable selectors targeting its hero summary and top FAQ answers. Google Assistant begins reading them for related queries.
