Keypad (Gen 2) how to increase volume of alarm speech + tones

I'm 3 weeks into configuring my system with two keypads for 3 entry doors (among other things not relevant to this issue). The issue I'm having is that the two audible events (voice notification, and countdown chirp) which occur whenever a door is opened in an alarmed state are FAR too quiet to be effective. I have two kids and two dogs, and when entering the house with them in even a mild-mannered state, it's not possible to hear the keypad sounds over just the sounds of movement over hardwood floor! In more detail, the voice notice volume is ALMOST loud enough, if it could be boosted maybe 25% more it would be sufficient to hear all the time. Unfortunately, the combination of the volume and pitch of the countdown tone (pleasant "whoomp, whoomp) can't be heard unless alone and dead quiet - we hear it at night if someone opens the door to let dogs out, but that's it! How can these events be boosted in volume to be effective enough NOT to trip a police visit? I'm not enabling the professional monitoring I'm paying for until I can guarantee my family won't get SWAT'ed by Amazon!
