Speak Text volume in Shortcut Automation.

I recently got iphone 17 (shifted from android) and had a shortcut set up where when I plugin the phone for charging, it would speak text like “charging started” as I usually forget to turn on the power when I plugin. But recently i noticed that when I plug it in, it speaks the text at full volume. Before it used to be according to my media/ringer volume.

Like I have another automation where when it’s 11:45pm my phone will go on silent mode and the media volume is set to 15%. Even after this setting, the charging text it on full volume.

Does anyone know what am I missing?
