Voice Search Optimization: What Changes When People Ask Out Loud

Voice Search Optimization: What Changes When People Ask Out Loud
Voice search optimization means making your business easy to name and easy to answer when someone asks a phone, a speaker or an AI assistant out loud. Shiri Melumad at Wharton found in 2023 that people who speak a search describe what they want in more detail, and they name brands more often. So the question for you is whether people know your name well enough to say it.

10,385

People across five studies. Speaking a search instead of typing it led to more specific queries, including more brand names.

How spoken searches differ from typed ones

When people type, they edit as they go. When they speak, they think first.
That's the heart of Melumad's paper, "Vocalizing Search," in the Journal of Consumer Research. She ran a survey, three experiments with spoken and typed Google searches, and one more experiment, 10,385 people in all. Speaking a query led people to describe what they wanted in more detail. They added brand names and what they planned to use the thing for. And they liked the results better.
Her explanation is plain. People worry a voice tool will get them wrong, so they plan the sentence before they say it. In Wharton's write-up she put it this way: "With voice, because we can't easily edit ourselves if we misspeak or are misunderstood, we tend to actually give more forethought to our query before indicating it." Her example: "best running shoe" turns into "What's the best Nike shoe for long-distance running?"
I got this wrong in an earlier version of this post. I said spoken searches run much longer than typed ones. The 29 words I quoted came from a 2018 study, and they were the length of the answer Google Home read out, not the question. And the Google study I cited says the opposite. In 2010, Maryam Kamvar and Doug Beeferman, two Google researchers working from the logs of a widely used voice search system, found "contrary to our intuition, that longer queries have a higher probability of being typed than shorter queries." People spoke when typing was awkward, when the question was about where they were, or when they wanted the answer hands-free. That study is old. But between the two, I'd say spoken searches are more specific, and I wouldn't claim they're longer.

What answers a voice search now

The thing answering a spoken question isn't the same as it was in 2018.
In March 2025, Google said it would move phone users from Google Assistant to Gemini. On September 3, 2026, it began removing Assistant from Android phones for good, with Gemini as the voice assistant there. If you've got an Android phone, the voice that answers you is now almost certainly Gemini. Speakers are moving more slowly. Google says that phone change doesn't touch its Nest and Home speakers, which are switching to Gemini for Home over time. By June 2026, Google was selling a new Google Home Speaker with Gemini built in.
Search changed too. In June 2025, Google launched Search Live, a back-and-forth voice conversation with AI Mode. You ask out loud, you hear an AI answer, and links show up on your screen. Google says it runs on a custom version of Gemini and uses what it calls query fan-out, splitting one question into several smaller searches. I explain fan-out in why authoritative pages lose AI search citations. Search Live opened to everyone in the US, in English, in September 2025, and Google's help page now says it's available wherever AI Mode is.
So as I see it, voice search in 2026 is mostly AI search said out loud. On Google, spoken questions go to AI Mode in Search, to Gemini on Android phones, and, as speakers switch over, to Gemini for Home. Some answers come from what a model already knows, and some come from a search it runs right then.

Why voice search favors businesses people know by name

This is the part of Melumad's work I think matters most for a business.
Because spoken queries name brands more often, she concluded that voice search helps bigger brands, the ones people already know well enough to say. Smaller, lesser-known brands may get squeezed out. In her words: "larger brands, like a Nike, may want consumers to use vocalized search, whereas smaller brands may benefit more from the vaguer queries that are generated from typing."
If someone asks for "a good plumber near me," every plumber nearby has a shot. If they ask whether a plumber they already know by name is open Saturday, only that one is in the running. A typed search leaves room to browse. A spoken one often starts with a name.
You can't make someone remember you. What you can do is make sure your name and what you do are written down the same way everywhere people and AI tools read about you. I wrote about why that matters in how ChatGPT gets its information. It's the work behind entity SEO, and it's where I'd put most of the voice effort.

Voice search SEO: how to write pages spoken answers can use

The voice search SEO advice on Google's first page still leans on one 2018 study. Backlinko looked at 10,000 Google Home results and found the average answer read aloud was 29 words. And 40.7% of those answers came from a featured snippet, the boxed answer at the top of Google.
Those numbers describe Google Home in early 2018, from the Google Assistant days, which have now ended on Android phones. I'd still take the lesson. A short, direct answer near the top of a section is easy for any tool to lift and say out loud.
Google says there's nothing special to do for its AI answers. Its guide for site owners says "there are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary." A page needs to be indexed and allowed to show a snippet to be eligible. Google says that doesn't guarantee it'll show up.
So here's how I'd write for it:
  • Put the question your customer would ask in the heading, in their words.
  • Answer it in the first sentence or two, plainly enough to read aloud.
  • Then give the detail underneath, for the person who wants more.
  • Use your business name and what you do in full, so the answer makes sense on its own.
I'd use the same structure for any AI answer. For featured snippets and Google's answer features, see our answer engine optimization work. For writing sections that stand on their own, see citation-ready content.

Voice search optimization for local businesses

Spoken questions are often local. In Kamvar and Beeferman's study, a search about where you are was one of the strongest signs a query would be spoken. "Where's a hardware store open now?" "What time does the bakery on Main close?"
The local data points the same way as Melumad. In BrightLocal's 2018 survey of 1,012 US consumers, people most often used voice search to learn more about local businesses they already knew, like an address, directions or a phone number.
For a local business, I'd start with your Google Business Profile. Google says one thing it weighs for local results is prominence, which it defines as how well-known a business is. That's Melumad's point again, from Google's side. Google also says complete, accurate profiles are more likely to show up. Hours, phone number, address and what you sell, all current. Our local business page goes further.

Why voice searches don't show up in your reports

Nothing in your reports tells you a search was spoken.
Google says clicks from AI Overviews and AI Mode are counted in Search Console with the rest of your web search traffic. I haven't seen any report that labels a search as spoken. And when someone hears an answer and calls you, there may be no click at all.
So I wouldn't try to measure voice by itself. I'd watch whether AI answers name your business and describe it right, typed or spoken, and ask new customers how they heard about you. Our measurement page covers what's worth tracking besides clicks.

What I'd do first about voice search

Ask your phone about your business out loud, the way a customer would. Then ask about the kind of thing you sell, without your name. Notice whether you come up, and what gets said about you.
If the answer is thin or wrong, I'd start with the basics above. Get your name and facts stated the same way everywhere, and write pages that answer real questions in plain words. And when someone calls because they heard your name, make it easy for them.

Common questions

What is voice search optimization?

Voice search optimization is the work of making your business easy to find and easy to name when someone asks a phone, speaker or AI assistant a question out loud. On Google, spoken questions now go to Gemini and to AI Mode through Search Live. Clear facts about your business and pages that answer questions plainly help whether people type or talk.

Is voice search still a thing now that AI assistants answer?

Yes, but it looks different. Google replaced Google Assistant with Gemini on Android phones starting in September 2026 and is moving its speakers to Gemini for Home over time. Its Search Live feature lets people talk back and forth with AI Mode. I think of voice search today as AI search said out loud, so the same work helps with both.

Do I need separate pages for voice queries?

I wouldn't make them. Google says there are no special optimizations needed to appear in AI Overviews or AI Mode, and Search Live runs on AI Mode. One good page that answers your customers' real questions plainly, near the top of each section, serves people whether they type or talk.

Does schema help with voice search?

Not much on its own, as far as the evidence goes. Backlinko's 2018 study of Google Home answers found pages with schema only slightly more often than the average page, and Google says no special schema is needed for its AI features. Google's speakable markup is a beta feature for news publishers on Google Assistant devices in the US, so it won't apply unless you publish news.

How do I know if people find me by voice?

The simplest way is to ask. When a new customer calls or walks in, ask how they heard about you, and listen for "I asked my phone." Your reports won't separate it out, since Search Console puts AI Mode traffic in with the rest of your web search numbers. Checking what AI answers say about your business every so often fills in the rest.
