How to Find and Delete What Your Smart Speaker Recorded

A client asked me to look at her Echo after her teenage son played back a clip of her arguing on the phone. He had found it in the Alexa app, under voice history, timestamped 10:41 on a Thursday night. Nobody had said the wake word. The speaker heard something close enough, recorded a few seconds, and sent them to Amazon, where they sat waiting for anyone with access to the household account.

That is the part most owners never check. Smart speakers are not recording everything all the time, but they do save what follows each wake, including the false ones, and the default settings keep a lot of it for a long while. Here is where those recordings live on Alexa, Google and Siri, how to delete them, and which settings stop them piling up again.

What actually gets saved, and why false wakes matter

Every speaker listens locally for its wake word. When it thinks it heard one, it starts streaming audio to the company's servers so the request can be processed. What happens to that audio afterwards depends on the platform and on settings most people never open.

The false wakes are the problem. A wake word detector is a guess, and it guesses wrong. Television dialogue, a name that sounds like "Alexa", a phrase like "OK, cool" near a Google speaker. In one family home where I reviewed the history with the owners' permission, I counted 23 entries over nine days that nobody remembered triggering. Most were a second or two of kitchen noise. Two were whole sentences of a private conversation.

Amazon labels many of these in the history with the line "Audio was not intended for Alexa." That label is useful, because it lets you see how often your particular room triggers the device. If you see more than a couple a day, the speaker is probably too close to a TV, or someone in the house has a name that keeps setting it off.

Part of why this happens is the same reason speakers struggle with certain words in the first place. Jonah wrote about it in why your smart speaker mishears the same word every time, and the mechanics apply to wake words too.

Finding and deleting recordings on each platform

Menu names drift between app versions, so treat these paths as the current shape rather than exact wording. I checked each one this autumn.

Amazon Alexa

In the Alexa app, open More, then Alexa Privacy, then Review Voice History. You can filter by date range and by device, play each clip, and delete them one at a time or in bulk. On the web, the same screen sits in your Amazon account under content and devices, then privacy settings.

To stop the backlog growing, go to Alexa Privacy, then Manage Your Alexa Data. Under voice recordings, you can choose to keep them until you delete them, keep them for 18 months, keep them for 3 months, or not save them at all. I set client homes to not save, unless they have a specific reason to keep history.

You can also enable voice deletion, which lets anyone in the room say "Alexa, delete what I just said" or "Alexa, delete everything I said today." Think about whether you want that in a shared house. It works both ways.

One change worth knowing: in March 2025 Amazon removed the setting that let a few Echo models, including the Echo Dot 4th generation and the Echo Show 10 and 15, process requests on the device without sending audio to the cloud. Those devices now send voice to Amazon like every other Echo. If you bought one for that feature, the deletion settings above are now your only control.

Google Assistant and Nest speakers

Google changed its default in 2020 so that audio recordings are not saved unless you opt in. Many accounts opted in years ago, often by tapping through a setup screen, so check anyway.

Go to myactivity.google.com, sign in with the account linked to the speaker, and open Web and App Activity. Look for the box labelled to include voice and audio activity. If it is ticked, recordings are being stored. Untick it to stop saving new ones. To delete old clips, filter your activity by Assistant and delete by date range.

Under the same activity controls you will find auto delete, with options of 3, 18 or 36 months. Choose 3 months if you want some history for troubleshooting routines. You can also say "Hey Google, delete what I said this week," which removes the transcript and any stored audio from that period.

Apple Siri and HomePod

Apple stores less by default. Audio recordings are kept only if you opted in to Improve Siri and Dictation. On an iPhone, go to Settings, then Privacy and Security, then Analytics and Improvements, and check that option. To delete what Apple holds, go to Settings, then Siri, then Siri and Dictation History, and tap delete. Do this from the device linked to your HomePod. If several people in the house use Siri on their own phones, each person has to delete their own history.

Deleting history does not make the speaker private

The common advice is to clear your recordings regularly and consider the job done. It is a good habit. It is also only half of it.

Deletion removes the audio file and, on most platforms, the transcript. It does not necessarily remove what the company learned from the request: that you asked for the weather in a certain town every morning, or ordered dog food every five weeks. Those patterns can live on in your purchase history, your ad profile or your account's activity log, each with its own settings. I go through this in more detail in reading a privacy policy before you buy, and the section on retention is the one worth reading slowly.

The microphone mute button is the only setting on a smart speaker that works without trusting a server.

Placement matters as much as settings. A speaker in the kitchen near the TV will false wake far more often than one on a bedside table. A speaker in a teenager's room records a teenager's life. If you have more than one, ask whether every room actually needs one. The differences in how each platform handles shared households are covered in Alexa or Google Home, what differs day to day.

Fifteen minutes this week

Open the voice history for every assistant in your home and scroll back thirty days. Count the entries marked as not intended, or that nobody remembers. If the number surprises you, move the worst offender away from the TV, set retention to the shortest option or to not save, and delete the backlog. Then put a reminder in your calendar for three months from now to check that nobody switched it back during a software update. It has happened to me twice.
