Can someone explain voice search?

People asking Siri, Google Assistant or Alexa out loud instead of typing. The queries come out longer and more like full questions ("where's the nearest tyre place open now") and a big share of them are local. There isn't really a separate voice SEO trick. The spoken answer usually comes from a featured snippet or the local pack, so clear direct answers on your pages and a properly filled Google Business Profile cover most of it.
