microG only works when signature spoofing is enabled for it, so if you have microG working, then that prerequisite should be met. (Edit: wrong, correction below) I haven't checked every Android distribution, but I can confirm that TTS voice downloads in Speech Services for Google works on LineageOS for microG. The original eSpeak project[1] that eSpeak NG was forked from did get abandoned, and eSpeak also has an older Android implementation[2] that also got abandoned. Edit: I'm surprised that microG works at all without signature spoofing, but based on your experience, I assume that Speech Services for Google needs either Play Services or microG (with signature spoofing enabled).
