Thank you for posting the extra details (through phone's speaker, Music stream, no background music and non-network voice). It seems that Google Text-to-speech engine is misbehaving on this device. Could you please try some other, non-Google voice to see if it will have the same problem? You could e.g. download Vocalizer TTS engine and install some voices from them. The voices are for purchase, but they let you use each voice for free for 1 week, so it's a good test tool. Or try totally free (though lower quality) RHVoice TTS engine.
If other voices work fine and Google TTS not, maybe uninstalling Google TTS (or uninstalling its updates, if can't be uninstalled completely), then rebooting device and installing it back could help.
I have the same problem, with it changing frequently.
And I can easily turn it off and reproduce it. :)
- Make sure under settings/Audio you have "For Each Voice" "Let music play in the background" checked.
- Leave "use old method" unchecked and Music (default) as your stream
- Easiest way to reproduce it is to start listening with your bluetooth headset.
- Watch the pop-up menu. In my case, I have volume at 4 of 25
- Now change the pitch by one setting. Volume switches to 13 of 15 (again, my settings, ymmv)
- Change the pitch again by one notch. Volume switches back to 4 of 25
- This does NOT seem to be related to the tts engine used, I have Google TTS as well as Vocalizer.
Unfortunately, this volume-flopping happens without you doing anything as well, most often at the start of chapters or in certain circumstances when another source grabs the stream.
For now, Generic can just turn off "Let music play in the background" and all should be well.
