While I was setting up piper TTS on my desktop, I came across the Kaldi project, which packages various open source TTS models for Android. They have a github page here with all of their releases packaged as TTS engines, which are usable system-wide without an internet connection and have pretty good quality.
If you want to look through that whole list, it's sorted by release version, then architecture, then by language (languages are sometimes ordered incorrectly). Make sure you open any installed engine before trying to change your engine in Android accessibility settings or the settings will crash. Also the apks all have the same package name, so you can only have one engine installed at a time.
I recommend the piper-en_US-glados and piper-en_US-lessac-medium models. Their pronunciation, handling of punctuation, and audio quality are good (the Glados model is robotic by design) and have short generation times.
