RHVoice TTS

I just installed the open source app called RHVoice in F-Droid that gives TTS support to phones without using Google libraries. It seems other apps are not using this as the preferred TTS engine in the missing TTS Accessibility settings.

I read in other threads here that the iode’ gurus were looking for an acceptable TTS engine-is that still true?
