Delete Google Voice History: Full Guide
To delete all Google voice history, go to your Google Account’s “Data & privacy” page, select “Web & App Activity,” and choose “Delete activity by date” with “All time” selected. This removes voice recordings, audio commands, and related text from your Google Assistant and Search activity. Below is a complete breakdown of what voice history includes, how to delete it on different devices, and how to keep it from coming back.
What Counts as Google Voice History
Google voice history includes any audio recording and transcript created when you speak to Google Assistant, use voice search, or dictate texts. This data is stored under your Google Account’s Web & App Activity, which also logs text searches, visited pages, and other interactions. Voice history specifically contains:
- Audio recordings of your voice, stored as .amr or .mp3 files
- Text transcripts of what you said
- Device information (phone model, app version)
- Time and location of the voice interaction
Google keeps these recordings to improve speech recognition and provide personalized responses. The data can be viewed or played back on the activity page, and you can delete individual items or the entire history.
How to Delete All Voice History on Desktop
Deleting everything from a computer takes about two minutes. Follow these steps:
- Go to myactivity.google.com and sign in to your Google account.
- In the left menu, click Data & privacy (or go directly to the activity page).
- Under “History settings,” click Web & App Activity.
- Click Manage activity.
- On the activity page, click the three-dot menu (⋮) in the search bar area.
- Choose Delete activity by date.
- Select All time from the dropdown.
- Click Delete and confirm.
This removes all activity logged under Web & App Activity, including voice recordings and transcripts. If you want to delete only voice items, filter by “Voice and Audio” in the search bar before deleting.
How to Delete Voice History on Android and iPhone
On mobile, the process is similar but accessed through the Google app or the account settings. On an Android phone:
- Open the Google app (or do a Google search in your browser).
- Tap your profile picture in the top-right corner.
- Select Search history (or “Manage your Google Account”).
- Tap the three-dot menu and choose Delete activity by date.
- Select All time and confirm.
On an iPhone or iPad, open the Google app, tap your profile picture, then tap “Search history” and follow the same steps. You can also use the Google Assistant app itself: say “Hey Google, delete my last conversation” or “delete my entire history” — the Assistant will prompt you to confirm.
What Happens When You Delete Voice History
Deleting voice history removes the audio files and transcripts from your account. Google states that it also deletes the associated data from its servers, though copies may remain in backup systems for a short period as part of routine maintenance. After deletion:
- Your Assistant will no longer have those recordings to learn from.
- Personalized voice recognition may become less accurate until new recordings are made.
- Any smart home routines or reminders that referenced specific voice commands will still work, but the command history is gone.
- If you use Google Home speakers, the recordings are stored in the same activity log, so deleting on one device affects all devices.
Deleting does not stop Google from collecting new voice data. To prevent future recordings, you must pause or turn off Web & App Activity entirely.
How to Auto-Delete Voice History
Instead of manually clearing history, you can set Google to automatically delete it after 3, 18, or 36 months. On the Web & App Activity page, click “Auto-delete” and choose a period. This applies to all activity, not just voice. If you want to keep text searches but delete only voice, you would need to manually filter and delete voice items periodically — there is no separate auto-delete toggle for voice alone.
Common Problems and Misconceptions
A frequent misconception is that deleting voice history also deletes your Google Assistant settings or your voice model. It does not. Your voice model (the “Hey Google” recognition) is separate and stored under “Voice Match” settings. To delete that, you must go to Assistant settings and remove the voice model.
Another issue: after deletion, some users find old voice commands still appear in the activity page for a few minutes. This is usually a synchronization delay — refresh the page or wait a bit. If they persist, check that you are signed into the correct account, as multiple Google accounts can store separate histories.
Also, deleting activity from the Google app on your phone does not delete activity from other devices. You must delete from the account-wide activity page to cover all devices.
Alternatives to Deleting: Pausing and Incognito
If you do not want to delete but want to stop new voice history, you can pause Web & App Activity. On the activity page, click “Turn off” under Web & App Activity. This stops all new activity logging, including voice. You can also use Incognito mode in the Google app or Chrome — voice searches made in Incognito are not saved to your account.
Another option is to use the Google Assistant’s privacy mode: say “Hey Google, turn on incognito mode” to prevent the current session from being saved. This is temporary and resets when you close the app.
Privacy and Security Considerations
Your voice history is stored on Google’s servers, protected by your Google account password. If someone gains access to your account, they can play back your voice recordings, which may contain sensitive information. Deleting history reduces this risk. Additionally, Google has faced scrutiny over how it handles voice data, including reports of human reviewers listening to anonymized recordings. Deleting your history does not necessarily remove recordings that were already processed for quality control, but it does remove them from your account.
For maximum privacy, you can also set up two-factor authentication on your Google account and review your activity regularly. Remember that deleting history is not the same as deleting your entire Google account — that is a separate, more drastic step.
Frequently Asked Questions
Does deleting voice history also delete my Google Assistant settings?
No. Your Assistant settings, including your voice match model, routines, and device preferences, are stored separately. Deleting activity only removes the log of voice commands and audio recordings, not the settings that govern how the Assistant behaves.
Can I delete only voice history and keep my search history?
Yes. On the activity page, use the search bar and filter by “Voice and Audio.” Then select all visible items and delete them. This removes only voice recordings and transcripts, leaving text searches intact. However, this must be done manually — there is no one-click filter for voice-only deletion.
Will deleting voice history affect my Google Home devices?
Yes, it removes the recorded commands from all devices linked to your account, including Google Home speakers and smart displays. After deletion, those devices will no longer have a record of past voice interactions, but they will continue to function normally for new commands.
How long does Google keep voice history if I don’t delete it?
By default, Google keeps Web & App Activity until you manually delete it or set an auto-delete period. You can choose to auto-delete after 3, 18, or 36 months. Without auto-delete, the data is kept indefinitely.
Is there a way to delete voice history using a voice command?
Yes. You can say “Hey Google, delete my last conversation” to remove the most recent interaction, or “Hey Google, delete my entire history” to clear all activity. The Assistant will ask for confirmation before deleting. This works on phones and smart speakers.
Does deleting voice history free up storage space on my phone?
No. Voice recordings are stored on Google’s servers, not on your phone. Deleting them does not free up local storage. To free up phone space, you would need to clear the Google app’s cache or delete downloaded audio files, which is unrelated to your voice history.
