TTS Engine on Vivo Smartohone

I am using a Vivo X300s Phone. On this phone Google TTS engine and also some free ones from F-Droid are installed. Google TTS engine is set to default, all other apps use Google TTS engine. With all other apps (Google Maps, Organicmaps, …) I can use these apps. Just in ABRP there is just the selection for Vivos AI Service TTS available (and that engine speaks chinese Language or very weird sounding “german” and “english” :-) ).

There should be a selection for Google TTS Engine or any alternative free one that is installed, not locked to Vivo AI Service TTS. System default TTS is Google TTS engine btw.
