Global reach: who's talking to search and how often

About 20.5% of internet users worldwide actively use voice search, according to Data Reportal for the second quarter of 2024. The peak came in the second quarter of 2022 (22.5%), after which the figure fluctuated between 19 and 21%. Growth has slowed, but the base remains huge: every fifth internet user is talking to search engines.

The number of voice assistants in the world has reached 8.4 billion. That's more than the entire population of Earth (8.3 billion), reports Statista. For comparison: in 2020 there were 4.2 billion. The doubling over four years happened partly because many homes run two or three assistants simultaneously: a speaker in the living room, a phone in your pocket, a car system.

Nearly a third of users (32%) replace typing with voice queries daily, according to PwC survey data. Another 29% ask quick questions by voice instead of browser search, and 35% check weather and news through an assistant. Two-fifths of adults (40%) perform voice search at least once a day, according to Edit.

The breakdown by gender is interesting: men outpace women on all device types. On smartphones the gap is 66% versus 55%, on desktop, 53% versus 30%, on tablets, 49% versus 31%, on smart speakers, 46% versus 26%, according to SocialMediaToday.

Mobile voice search: the phone as the main microphone

27% of people use voice search on mobile devices, confirms recent DemandSage data. More than half (58.6%) of US consumers have tried voice search at least once. But 41.4% haven't used this feature yet, which means there's still significant room for growth.

Young people are leading. Among users aged 18-34, 77% use voice search on smartphones, 37% on tablets, and 38% on desktop. In the 55+ age group, similar figures drop to 30%, 9%, and 15% respectively. Every fourth user aged 16-24 launches voice search on mobile monthly. For the 55-64 audience, this figure is only 9%, according to GlobalWebIndex.

For local search, mobile users turn to voice three times more often than to text input. Voice search results load in an average of 4.6 seconds, 52% faster than regular search results (8.8 seconds), confirms Backlinko.

Smart speakers: a market that won't stop

The smart speaker market was valued at $15.1 billion in 2025 and will grow to $16.6 billion by 2026, according to Fortune Business Insights. By 2034, $34 billion is forecast with an average annual growth rate of 9.4%.

42.2% of all smart speakers worldwide are installed in the US. The country remains the largest market, according to Canalys analysts. North America overall holds 40.2% of the global market. In 2018, every sixth American (16%) had a smart speaker, and by 2019, 24% of US households already owned such a device. Moreover, 4 out of 10 families had more than one speaker.

By 2021, smart speakers had surpassed tablets in sales. A Canalys report recorded a historic turning point: tablet sales are declining while the speaker market grows by tens of percent annually. Particularly rapidly in the Asia-Pacific region, where the middle class is growing and interest in technology is rising.

94% of all smart speakers sold worldwide are manufactured by Google and Amazon, according to TechRepublic. Third place is shared by Apple HomePod and Alexa-compatible platform devices. Amazon Echo holds more than two-thirds of the US market, with Google Home (Nest) coming second.

In 2026, more than 150 million people in the US alone use smart speakers. The 2018 forecast of 55% of households with speakers by 2022, PRNewswire data, was long ago exceeded.

Voice assistants: accuracy, reach, and competition

Google Assistant is installed on more than 400 million devices, according to Voicebot.ai. Siri has about 500 million users globally, including 86.5 million in the US, according to Keywords Everywhere estimates. Amazon's Alexa has about 77.2 million.

Siri has about 83% answer accuracy, and Alexa about 80%. English remains the most accurate language for voice search: Google has achieved 95% accuracy in recognizing English speech. The technology supports more than 120 languages and dialects, and quality in other languages grows every year thanks to machine learning.

The average Google voice search result contains just 29 words. Backlinko analyzed 10,000 Google Home answers: the assistant gives a compressed answer, not a wall of text. Only 1.71% of exact keywords from the query appear in the result's title tag. Google scans the entire page and delivers the most relevant snippet.

20% of all voice queries consist of a combination of just 25 keywords. The most common: "how," "what," "best," and "easy," according to seoClarity. 93% of users overall are satisfied with their voice assistants, PwC research identifies the main criteria: answer accuracy (73%), time savings (59%), and life simplification (55%).

Voice commerce: shopping without a screen

43% of voice device owners have used them for online shopping, according to Narvar. Mainly these are inexpensive and familiar products: food, groceries, household items. For large purchases, users still prefer screens: they need to compare prices, read reviews, and look at photos.

19% of smart speaker owners have already made purchases through an assistant, and 33% plan to try. 82% of shoppers research a product or service online before purchasing, and a significant portion of this research already happens by voice, according to Think with Google.

In the US, 38.8 million people (13.6% of the population) use smart speakers for purchase-related actions. 52% of speaker owners want to receive information about discounts and promotions from brands, 48% expect personalized recommendations, BrightLocal survey.

Local business and voice search

58% of US consumers have searched for local companies through voice search, according to BrightLocal research. 76% of smart speaker owners do local voice search at least once a week, 46% daily.

The most in-demand local voice search categories:

On mobile devices, local voice search is even more popular: users turn to voice three times more often than typing when searching for nearby businesses. Phrases like "near me" and local queries make up 76% of all voice searches, DemandSage report data, and this share is growing.

Seven out of ten users (74%) launch a voice assistant for music, 66% check weather, 58% set alarms and reminders, reports BrightLocal. But the share of "serious" queries grows every year: searching for doctors (28% of voice queries in the medical category), dentists (24%), auto services (23%).

Technology: languages, speed, and NLP

Google Assistant supports more than 120 languages and their variants. Speech recognition technology is based on machine learning: the more people use voice search, the more accurate the results. English is the most accurate language (95%), but quality in other languages is catching up with each model update.

Speed is a key factor. 90% of users consider voice search easier than traditional search, 70% cite speed as the reason, according to DemandSage research.

Voice search also changes the structure of results. Backlinko research showed: 40.7% of voice search answers are taken from Featured Snippets. High domain authority and the number of social signals directly correlate with appearing in Google voice answers.

If you haven't started optimizing your site for search engines yet, now is the perfect time to include voice queries in your strategy. Every day of delay means customers that competitors hear, not you.
