Good voice Quality / Bad, limited implementation Rated 2 out of 5 stars

The Quality of the voice is very good.

Unfortunately, the TTS (= Text to Speech),
is limited to 1,000 (one thousand) characters, only!.

That means that trying to listen
to a longer article (for a visually-impaired person like me),
makes the IM-TTS impractical:

...copy 1000 chars, paste, listen,
copy another 1000 chars, paste, listen, etc.
Well, it's just not usable in the real world.

There are other free TTS services online,
with 10,000 characters...too bad for IM-TTS...

I would use them
if they had a more generous quota of text,
to be heard ALL AT ONCE.

This review is for a previous version of the add-on (4.10).
