Note : If you have used an iPhone, iPad or iPod touch during the initial setup of the HomePod speaker, then various settings have been adopted , For example, if you are using VoiceOver on iPhone, the feature for the HomePod will automatically be activated. If you do not want to do this, you can disable the feature relatively easily.
How to (de) activate VoiceOver on the HomePod
To turn the VoiceOver feature on or off, use an iOS Device logged in with the same Apple ID as the HomePod. Then open the home app and place your finger on the "Home" or "Rooms" tab on the HomePod icon. After a short while more options will appear. Touch Settings.
Now scroll down until you see the entry "Accessibility". Tap on it and then select "VoiceOver". Here you can deactivate / activate the feature by moving the slider to the left or to the right. Upon activation, you also have the option of making additional settings. In the menu, set the speech tempo, the time between a double tap, and audio ducking. Enabling the latter feature reduces the volume of audio playback during VoiceOver output.
