The Rave 3S speaker has a voice prompt function when turning on/off or connecting/disconnecting via Bluetooth.

If you don't wish to activate voice prompts you can download the soundcore app on your phone from Google Play Store or the App Store and then use the app to disable the voice prompt feature. Once you’ve turned it off, you will not hear a sound when turning it on/off or when connecting/disconnecting the speaker via Bluetooth.

Here are more details:

1. Open the soundcore app and enter the Rave 3S interface.

2. Click the Settings button in the upper right corner.

3. Go to "Speaker Prompts" to turn notification sounds on or off.
