Smart speakers and privacy: is Alexa always listening?

What Alexa, Google and Siri speakers hear, what gets saved, and the settings to check.

The short version

A smart speaker listens on the device for its wake word (“Alexa”, “Hey Google”, “Siri”). Only after it hears that does it send what you say to the company to answer. Recordings may be saved to your account, and you can review and delete them, and press the mic-off button when you want privacy.

📅 Checked as of October 2026. Apps and rules change, so check the sources below if something looks different.

How listening works

  • Waiting: the speaker checks the sound in the room for its wake word, locally, on the device.
  • Awake: a light turns on and your request goes over the internet to the company’s computers.
  • Mistakes: sometimes it wakes up by accident on a word that sounds similar, and records a few seconds you didn’t mean to send.
Think of it like this: it’s like a dog that dozes until it hears its name. It perks up at its name, and sometimes at a word that sounds a bit like it.

What changed with Alexa in 2025

Since March 28, 2025, Amazon no longer offers Do Not Send Voice Recordings, a setting on three Echo models (Echo Dot 4th gen, Echo Show 10 and Echo Show 15) that turned your voice into text on the device instead of sending the recording. Requests now go to Amazon’s cloud, which powers its newer Alexa+ assistant. You can still choose not to save recordings and delete your history in the Alexa app’s privacy settings.

Settings worth checking (all brands)

  • Voice history: review it, delete it, or set it to auto-delete. Alexa app: More › Alexa Privacy. Google Home: Settings › Privacy or My Activity. Apple: Siri requests aren’t saved by default unless you opt in to Improve Siri & Dictation.
  • Human review: turn off options that let staff review recordings, if offered.
  • Voice purchasing: turn it off or add a PIN so a TV ad or a child can’t order things.
  • Mic-off button: press it during private conversations. The light shows red (or orange) when the mic is off.
  • Updates: keep the app and device updated, and use a strong Wi-Fi password.

Should I get one?

If hands-free timers, music and calling help you, especially with limited mobility or eyesight, the convenience can be worth it. If the idea of a listening device bothers you, keep it out of the bedroom, or skip it. Both are reasonable.

Quick tips

  • Open your speaker’s app and set recordings to auto-delete.
  • Turn off voice purchasing or add a PIN.
  • Use the mic-off button when you want quiet.
