Voice search lets you speak a question instead of typing it

Voice search is a feature built into most phones, tablets, and computers that listens when you speak and searches the internet for what you said. Instead of opening a search engine and typing "weather tomorrow," you can say those words aloud and get results in seconds. The feature works on Android phones, iPhones, Windows computers, and Macs — though the steps to turn it on differ slightly for each.

Voice search is useful when your hands are full, when you are driving, or when typing is slower than speaking. It also works within apps: you can search YouTube by voice, look up songs on Spotify by voice, or find videos on your phone's camera roll by voice. The feature is off by default on most devices, which means you have to enable it yourself before you can use it.

Key Takeaways

  • Voice search is built into Android, iPhone, Windows, and Mac devices but must be turned on in settings before you can use it.
  • On Android phones, voice search is usually enabled through Google Settings or by holding down the home button and saying "Hey Google."
  • On iPhones, you enable voice search by turning on Siri in Settings, then saying "Hey Siri" followed by your question.
  • On Windows computers, Cortana (the voice assistant) is turned on through Settings and activated by saying "Hey Cortana" or clicking the microphone icon.
  • Once enabled, voice search works in most apps and web browsers, though some apps require you to tap a microphone icon first.

Enabling voice search on Android phones

On Android phones, voice search is powered by Google Assistant. To turn it on, open Settings, scroll down and tap Google, then tap Manage your Google Account. Tap the Search, information & Voice tab at the top, then tap Voice. Toggle on Voice set up and Hey Google. This lets you say "Hey Google" followed by a question, and your phone will search for it automatically.

If you want to use voice search without saying "Hey Google" first, you can hold down your phone's home button (or power button on newer phones) and speak your question. Some Android phones let you customize which button activates voice search — check your phone's settings under Buttons or Gestures to see if this option is available. Once voice search is on, you can use it on your home screen, in Google Search, in Chrome, and in many third-party apps.

Enabling voice search on iPhones

On iPhones, voice search uses Siri, Apple's voice assistant. To turn it on, open Settings, tap Siri & Search, then toggle on Listen for "Hey Siri". Your phone will ask you to say "Hey Siri" a few times so it learns your voice. After that, you can say "Hey Siri" followed by any question — "What's the weather?" or "How do I reset my password?" — and Siri will search for the answer.

You can also set up Siri by holding down the side button (on newer iPhones) or the home button (on older models) and speaking your question. If you do not want to use the "Hey Siri" voice command, you can still use voice search by tapping the microphone icon in the keyboard whenever you see a search box. This works in Safari, Maps, the App Store, and most other built-in Apple apps.

Enabling voice search on Windows computers

On Windows computers, voice search is handled by Cortana, Microsoft's voice assistant. To turn it on, click the Start button, type Cortana settings, and press Enter. In the Cortana window, toggle on Microphone under the Microphone section. You can also toggle on Hey Cortana to set up voice search by saying those words aloud, though this requires a microphone connected to your computer.

Once Cortana is on, you can click the microphone icon in the Windows search bar (at the bottom left of your screen) and speak your search. You can also say "Hey Cortana" if you have enabled that feature. Voice search on Windows works in the search bar, in Microsoft Edge (the built-in browser), and in some Windows apps. If your computer does not have a microphone, you will need to plug one in via USB or use a headset with a built-in microphone.

Enabling voice search on Mac computers

On Mac computers, voice search is powered by Siri. To turn it on, click the Apple menu, select System Settings, then click Siri & Spotlight in the sidebar. Toggle on Listen for "Hey Siri". Your Mac will ask you to say "Hey Siri" several times so it recognizes your voice. After that, you can say "Hey Siri" followed by a search term or question from anywhere on your Mac.

You can also click the Siri icon (usually in the top right corner of your screen) and speak your search. Voice search on Mac works in Spotlight (the search tool), Safari, Maps, and most other built-in apps. If your Mac does not have a built-in microphone (some older desktop models do not), you will need to connect an external microphone via USB or Bluetooth.

Using voice search once it is turned on

After you enable voice search on your device, using it is straightforward. On Android, say "Hey Google" followed by your question. On iPhone or Mac, say "Hey Siri" followed by your question. On Windows, say "Hey Cortana" or click the microphone icon in the search bar and speak. Speak clearly and at a normal pace — the device does not need you to shout, and background noise can interfere with accuracy.

Voice search works best for straightforward, direct questions: "What time is sunset?" or "Show me Italian restaurants near me." It also works for commands: "Set a timer for 10 minutes" or "Call Mom." If your device does not understand you, it will show you what it heard and ask if you want to try again. You can also edit what it heard by tapping the text and typing a correction.

Troubleshooting voice search if it is not working

If voice search is on but not responding when you speak, check that your device's microphone is not muted. On phones, look for a mute switch on the side of the device. On computers, check that the microphone is not disabled in your sound settings. Also make sure your device is connected to the internet — voice search requires an active connection to send your voice to the company's servers and get results back.

If voice search is still not working, restart your device and try again. On Android, you can also try clearing the cache for Google App: go to Settings, tap Apps, find Google, tap Storage, and tap Clear Cache. On iPhone, try disabling and re-enabling Siri in Settings. On Windows and Mac, restart Cortana or Siri by toggling the feature off and on again in your settings.

Frequently Asked Questions

Does voice search work offline?

No, voice search requires an internet connection. Your device sends your voice to the company's servers (Google, Apple, or Microsoft), which process it and send back results. Without internet, the microphone will not set up or will show an error message.

Can I use voice search in other languages?

Yes. On Android, go to Google Settings and tap Languages to add a language. On iPhone, go to Settings > Siri & Search and tap Language to change it. Siri and Google Assistant will then listen for and respond in that language.

Is voice search private, or does it record what I say?

Your voice is sent to the company's servers to process your search, and companies keep a record of voice searches for a limited time. You can delete your voice history in your account settings. If privacy is a concern, you can turn off voice search and use the keyboard instead.

Why does voice search sometimes misunderstand what I said?

Background noise, accents, and unclear speech can affect accuracy. Speak clearly at a normal pace in a quiet environment. If the device misunderstands, you can edit the text it heard or try again with different wording.

Can I use voice search while driving?

Yes, and it is safer than typing. However, check your phone's laws in your area — some places restrict phone use while driving even if you are using voice commands. Always keep your eyes on the road and set up voice search before you start driving.
