Voice search behavior ranges from quick information requests to radio, music, reminders, and connected-home controls. The available evidence below combines UK measurements from 2022–2025 with U.S. surveys from 2017 and 2020, so the geography and measurement period matter when comparing results.

Adoption and platform use
In the UK, 54% of adults said they had used a voice assistant in the previous three months in Ofcom’s 2025 Audio Survey. Among UK voice-assistant users, Amazon Alexa was reported by 66%, Google Assistant by 31%, and Apple Siri by 28%. Smaller reported shares used Samsung Bixby (4%) or Microsoft Cortana (3%). These platform figures describe use among voice-assistant users, not shares of the entire adult population. Ofcom, Audio Listening in the UK 2025
An older U.S. benchmark shows a different device mix. In Pew Research Center’s spring 2017 survey, 46% of U.S. adults said they used voice assistants to interact with smartphones or other devices. Smartphone use alone was reported by 42%, compared with 14% on a computer or tablet and 8% on a standalone device such as Amazon Echo or Google Home. The 2017 figures are historical measurements and should not be treated as current adoption estimates.

| Measure | Result | Geography and period |
|---|---|---|
| Adults using a voice assistant recently | 54% | UK, 2025 Audio Survey |
| Adults using voice assistants on smartphones or other devices | 46% | U.S., spring 2017 |
| UK users reporting Amazon Alexa | 66% | UK, 2025 Audio Survey |
| U.S. adults using a standalone assistant device | 8% | U.S., spring 2017 |
The contrast between the UK platform results and the older U.S. device results is useful for context, but it is not a like-for-like market comparison. The surveys used different countries, dates, and question wording.
What people ask voice assistants to do
Voice behavior is strongly connected to routine information and household tasks. In Ofcom’s 2024 Technology Tracker, reported in 2025, 63% of UK smart-speaker owners used their device to listen to music through a streaming service. Live radio was used by 57%, weather reports by 40%, alarms and reminders by 39%, answers to questions by 38%, and news reports by 24%. Ofcom, Audio Listening in the UK 2025
A one-week diary exercise provides another view of behavior. Among 100 UK smart-speaker users in autumn 2022, 73 reported searching for information online or asking general questions. Weather reports were reported by 82, while 79 said they used the device as an alarm or personal-schedule reminder. Travel information or updates were reported by 40.

The two UK sources measure different things. The Technology Tracker reports the share of owners who used listed functions, while the diary exercise records reported behavior during one week among participants. The diary figures therefore should not be read as annual or population-wide usage rates.
The pattern is consistent across both measurements: voice assistants support immediate, practical requests. Weather, schedules, travel, and general questions are all tasks where speaking can be faster than navigating a screen. Music and radio are also prominent, showing that voice assistants are used for content access as well as search-like information retrieval.
Audio and content behavior
Among UK voice-assistant users in Ofcom’s 2025 Audio Survey, 71% used an assistant to listen to radio stations. The same proportion, 71%, used an assistant to listen to other audio such as streaming music, podcasts, or on-demand audio. Voice is therefore part of the content-access pathway, not only a way to request factual answers. Ofcom, Audio Listening in the UK 2025
The device used for the request varied by content type. Among UK voice-assistant users who listened to radio, 54% made their voice requests through a smart speaker and 20% through a smartphone. For non-radio audio, 44% used a smart speaker and 30% used a smartphone. These percentages describe the reported device route for the relevant listening groups.
Listening-time data adds a measure of content share. In the 2024 IPA TouchPoints SuperHub data reported by Ofcom in 2025, online live radio accounted for 55% of time spent listening through smart speakers among UK adults aged 15 and over. Streamed music accounted for 36%. Among UK smart-speaker users aged 15–34, streamed music accounted for 58% of listening time, while online live radio accounted for 33%.
| Listening measure | All UK adults aged 15+ | UK users aged 15–34 |
|---|---|---|
| Online live radio share of smart-speaker listening time | 55% | 33% |
| Streamed music share of smart-speaker listening time | 36% | 58% |
The age comparison indicates a different content balance within smart-speaker listening. Live radio represented the larger share for all adults aged 15 and over, while streamed music represented the larger share among users aged 15–34. These are listening-time shares from the 2024 measurement period, not percentages of people using each format. Ofcom, Audio Listening in the UK 2025
Locations and result performance
Voice assistants are used in several everyday settings. In the UK 2025 Audio Survey, 37% of voice-assistant users used an assistant in the living room, 36% in the kitchen, and 13% in the car. The living room and kitchen were therefore the leading locations among the listed settings, while in-car use was reported by a smaller share. Ofcom, Audio Listening in the UK 2025
Smart speakers also became a larger part of UK radio listening over the supplied periods. They accounted for 14% of UK radio listening in Q1 2023 and 18% in Q1 2025. This is a change in the share of radio listening attributed to smart speakers, not a direct measure of voice-search query growth.
Performance is not always reliable. Among UK smart-speaker users who used the device for radio, 58% said it had played the wrong thing when asked for a particular station or programme. That result matters for publishers, broadcasters, and brands: being requested by voice does not guarantee that the intended result is delivered.
Source awareness is also limited for news. Among UK smart-speaker users who used the device for news, 17% were always aware of the original news source and 34% were sometimes aware. Another 8% were never aware of the original source, while 38% said they never used the device for news. These responses come from the 2025 Audio Survey and apply to the survey’s defined smart-speaker groups. Ofcom, Audio Listening in the UK 2025
Age and child patterns
Pew Research Center found an age difference in U.S. voice-assistant use in its spring 2017 survey. Fifty-five percent of adults aged 18–49 said they used voice assistants, compared with 37% of adults aged 50 and older. Because the survey is historical, the figures describe behavior at that time rather than current age-group adoption. Pew Research Center, “Nearly half of Americans use digital voice assistants, mostly on their smartphones”
Children’s use was measured through U.S. parents in a March 2–15, 2020 survey. Thirty-six percent of parents of a child aged 11 or younger said the child had ever used or interacted with a voice-activated assistant. Among parents of children who used an assistant, 78% of those with a child aged 5–11 said the child used it to get information, compared with 29% of those with a child aged 4 or younger.
Entertainment uses also differed by child age. Among parents of assistant-using children, 54% of those with a child aged 5–11 said the child used it to hear jokes, compared with 24% for children aged 4 or younger. Playing games was reported by 34% for children aged 5–11 and 16% for children aged 4 or younger. Pew Research Center, “Children’s engagement with digital devices, screen time”
Reported interaction also varied with parental education. Among U.S. parents of children under 12, voice-assistant interaction was reported by 26% of parents with a high-school education or less, 38% with some college, and 42% with a college degree. These are parent-reported results from March 2–15, 2020, not direct interviews with children.
Motivations, accuracy, and barriers
Convenience was the leading motivation in the supplied U.S. evidence. In Pew Research Center’s spring 2017 survey, 55% of U.S. voice-assistant users cited hands-free device interaction as a major reason for use. Fun was a major reason for 23%, while 22% said speaking felt more natural than typing. Ease of use for children was cited by 14%.
Voice assistants were also used to control connected systems. Twenty-six percent of U.S. adopters said they used assistants to connect remotely to systems such as locks, lighting, or heating. This extends voice behavior beyond search and content into household action. Pew Research Center, “Nearly half of Americans use digital voice assistants, mostly on their smartphones”
Accuracy was mixed in the same historical survey. Thirty-nine percent of U.S. voice-assistant users said assistants accurately responded to commands most of the time, while 42% said they did so some of the time. Sixteen percent said accurate responses occurred not very often. The categories describe user perceptions of command response, not a technical accuracy test.
Among U.S. adults who did not use voice assistants, 61% said they were simply not interested. Privacy concerns were cited by 27%. These barriers help explain why adoption statistics should not be treated as universal demand: some people value hands-free convenience, while others remain uninterested or concerned about privacy.

For SEO and content planning, the measurements point toward several distinct voice behaviors: concise information requests, routine utility queries, audio discovery, and spoken navigation of household or device functions. The evidence also shows why context matters. Results vary by country, age, device, setting, survey period, and whether the measure captures ownership, reported use, listening time, or performance experience.
