How to adjust Siri voice volume on Apple Watch

With watchOS 5, Series 3 and newer owners can adjust the volume of Siri voice responses

With watchOS 5, you can control how loud Siri speaks her responses on Apple Watch.

A louder speaker and a more powerful microphone on Series 3 and newer watches makes it easier to hear Siri’s responses, phone calls, even your music and more, all without headphones.


  • watchOS 5 brings ability to adjust Siri voice volume.
  • This is especially useful on Series 4 which has an improved speaker.
  • You can also choose when Siri speaks in Settings.
  • Siri must download her voice before she can speak.

In order to help Apple Watch wearers customize their Siri experience, watchOS includes a dedicated voice volume control for Siri on Apple Watch Series 3 and newer models.

This wasn’t possible on older watchOS editions.


To reiterate, this feature requires the following:

  • Apple Watch Series 3 or newer
  • watchOS 5 or higher
  • Internet connectivity

If you have a Series 2 or 1 device, this handy feature will be unavailable to you due to hardware constraints so Siri will default to display replies on your wrist along with text or images.

How to adjust Siri volume on Apple Watch

To set the volume of spoken Siri responses separately from the main system volume.

1) Open Settings on your Apple Watch.

2) Choose General from the list.

3) Tap Siri.

4) Scroll down until you stumble upon the heading Voice Volume — Speaker, then tap on the slider below and turn the Digital Crown to adjust how loud or quiet you’d like Siri to be.

If Siri doesn’t speak, watchOS may not have downloaded its voice.

To give the download time to complete, try charging your Apple Watch overnight and be sure you’re connected to Wi-Fi. You can check the status of the download on the watch itself by going to Settings → General → Siri, then scroll to Siri Voice.

Choosing when Siri speaks

To choose when Siri speaks (Series 3 or newer), scroll down to Voice Feedback and choose:

  • Always On: Siri will always speak out her responses, even in silent mode.
  • Control With Silent Mode: Siri goes mum when you set the watch to silent, but continues talking to you when the watch is connected to Bluetooth headphones.
  • Headphones Only: Siri voice feedback is limited to Bluetooth headphones.

Curiously enough, a version of Siri found on iPhone, iPad and HomePod currently does not permit users to set the volume of voice commands independently of the main system volume.
