Is indexing supposed to be like per reading block, or like one global? Is
the idea
that you can be reading a buffer, go to another buffer, read some of it, then
back and continue? IE: Index per "reading block"?

Assuming it is global for simplicity, it is still a heavy lift for
implementation on
Mac and Windows.

As they do not natively report back as words are spoken, now
you can get this behavior at an "Utterance" level, by installing hooks and
and tracking those. With that you would need to additionally keep copies of
the future
utterances, even if they already where queued with the TTS.

Considered from the POV of index per reading block, then you need to find
ways to ident
each one and its position and index them and continue reading.

Sounds neat, but at least for my servers, right now, the juice isn't worth
the sqeeze, I
am still trying to get basic stuff like pitch multipliers working on windows
via wave
mangling and other basic features, hehe.
