I ordered two such modules. The past when the female voice is turned on says something about bluetooth, this module simply silent after turning on and makes sounds only when the device is connected and disconnected to it by bluetooth. Volume-sufficient for such sizes, sound quality-average, for such a price category-a very good thing! i recommend.
