Okay, I was able to get to an archived version of the website:
https://web.archive.org/web/20230530160710/http://www.cross-plus-a.com/balabolka.htm
The download links work.
From that archived site comes the following description of the program:
________________________________________________________________________
Balabolka is a Text-To-Speech (TTS) program. All computer voices
installed on your system are available to Balabolka. The on-screen text
can be saved as an audio file. The program can read the clipboard
content, extract text from documents, customize font and background
colour, control reading from the system tray or by the global hotkeys.
Balabolka supports text file formats: AZW, AZW3, CHM, DjVu, DOC, DOCX,
EML, EPUB, FB2, FB3, HTML, LIT, MD, MOBI, ODP, ODS, ODT, PDB, PRC, PDF,
PPT, PPTX, RTF, TCR, WPD, XLS, XLSX.
Balabolka
The program uses various versions of Microsoft Speech API (SAPI); it
allows to alter a voice's parameters, including rate and pitch. The user
can apply a special substitution list to improve the quality of the
voice's articulation. This feature is useful when you want to change the
spelling of words. The rules for the pronunciation correction use the
syntax of regular expressions.
Balabolka can save the synchronized text in external LRC files or in MP3
tags inside the audio files. When an audio file is played with players
on a computer or on modern digital audio players, the text is displayed
synchronously (at the same way, as lyrics for songs).

Looks like it has some features I would like. That is, if W7 actually
came with more voices other than only one, single female voice
available. It's like fingernails on a chalkboard to me.
I just noticed on the Balabolka website if one scrolls down to where it
says "Microsoft Speech Platform", there are 28 runtime language links
listed -all of which are have female names. A little bit of reverse
sexism here from M$ IMO.
Check out this discussion about the problem and the canned M$ non-reply
from "Ravinath P":

Within that discussion, I found a link to this set of complex
instructions for "Changing Windows Narrator's Voice":
https://www.webbie.org.uk/changingNarratorToUseADifferentSAPI5Voice.htm
and this M$ page, where one can supposedly download additional free
voices from the megacorp:

I've never been able to make any of it work, however.
