Adjusting volume of beep sound with dictation feature

I just figured this out and I wanted to share this with everyone. When texting on my IPhone7, I use the dictation feature a lot. It is the microphone icon next to the space bar on the keyboard. I noticed that when I hit the icon, there is a very loud beep sound, which also beeps again when I'm done dictating. I wanted to lower this volume and couldn't find it anywhere in settings. This is how you do it...

While texting, hit the microphone icon to start the dictation feature, don't talk. Use the volume buttons on the side of the phone to turn the volume up or down. Hit the icon again to disable the dictation feature. Then try hitting it again to test the volume of the beep.

Ta-Da! I hope this helps someone.
