This post is from the WWDC26 Foundation Models Q&A.

Whisper and other STT APIs let you pass a custom vocabulary or initial_prompt to bias recognition toward domain-specific proper nouns. In the App Intents / Siri stack, is there an equivalent way to supply dynamic, per-user term lists — for example favorites or recently used items — to improve how spoken names are transcribed or resolved?

We have completely reimagined Siri to be a profoundly more capable assistant, including improved speech recognition, and custom vocabulary may not be necessary. To help Siri's speech recognition better understand your entities, adopt IndexedEntity and index your entities in Spotlight.
