Suggestions for Text-To-Speech (TTS) from Org sources?

Suggestions for Text-To-Speech (TTS) from Org sources?

[Jens Lechtenboerger]

Dear all,

does someone here produce audio via Text-To-Speech (TTS) from Org
sources?  I plan to do that in the context of emacs-reveal to
generate voice-over for reveal.js presentations, with open questions
[1] concerning my initial, experimental approach.

Currently, I like the default model of Coqui-AI TTS [2] and
Microsoft SpeechT5 [3] best.  Any suggestions for free and open TTS
implementations that produce even better results?  Other models of
Coqui-AI?  The solution should work without GPU support, which seems
to rule out Suno Bark [4].

The above models do not pronounce numbers/digits, and they fail to
pronounce most acronyms.  In a preprocessing step I could replace
those.  I use preprocessing anyways to get rid of Org markup that
might confuse the language models.  Anyone here who did that
already?  Maybe gruut [5] in conjunction with SSML [6] handling?

Any other suggestions?

Best wishes
Jens

I've turned OrgMode files into audio desktops

It was pretty simple

Just find the code that reveals what an icon is when you hover over it &
pipe it to some text-to-speech engine & then on to usual routes

Thank you for the reply.  In my case (GNU/Linux), I guess that the
usual text-to-speech engine is espeak.  I find its speech quality to
be disappointing (much worse than the language models that I
mentioned earlier).  I am looking for (near-) human quality...

Emacspeak is a mature Emacs solution for TTS. However, it aims blind
users, not presentations. Still,
http://tvraman.github.io/emacspeak/manual/Quick-Installation.html might
be a good starting point for TTS options.

Thank you for the suggestion.  With espeak this indeed pronounces
numbers and abbreviations but its audio quality it not good enough
for my purposes.  I am looking for (near-) human voices...

using mbrola is probably as good as possible with free software:
https://en.wikipedia.org/wiki/MBROLA

still not perfect, but much better than the builtin voices of espeak or
festival (YYMV).

This sounds promising.  I’ll check it out.

* eSpeak seems to focus on small footprints & a "format synthesis" method

* Suggest using Festival with MBrola:

https://www.cstr.ed.ac.uk/projects/festival/mbrola.html

https://www.cstr.ed.ac.uk/projects/festival/

and/or just install FestivalLite:

apt-get install -f -y --force-yes flite

* Note EmacSpeak {mentioned in another email} is written by OrgMode user &
programmer TV Raman--not sure EmacSpeak will help you at all; but it might
be interesting for you

** Klaus Knopper distributes some very interesting free software that
includes an audio-desktop called ADRIANE that maybe you can look at--I'd
love to hear what you find out if you do:

https://www.knopper.net/knoppix-adriane/index-en.html

** Knopper invented the "run Linux entirely from a cdrom" craze--which
still is very useful in many ways--suggest you give Knoppix & Adriane a look

fenrir-screenreader is also available.
https://nashcentral.duckdns.org/projects/Jenux
uses fenrir by default.
Klaus Knopper's public key I haven't been able to find and none of his
email addresses seem to be working any longer either for the ones I found.
You have a chance of getting a good version of knoppix if you download
with a good bittorrent client and make sure your encryption required is
turned on and make sure of integrity checks.

The knoppix signing keys seem to be around here:

Look here:

  http://knoppix.net/

...and consider buying a CD (yes, that's still a thing ;-) or a stick
to support development.

Why does this happen?

The gpg command given in the faq does not return what the faq claims will
be returned.
Look for the public key of Klaus Knopper:
bash: Look: command not found
bash-5.1$  gpg --keyserver pool.sks-keyservers.net --search-keys "Klaus
Knopper"
gpg: error searching keyserver: Server indicated a failure
gpg: keyserver search failed: Server indicated a failure
bash-5.1$

Hm. Keyservers seem to be a dying species these days. Try

fenrir-screenreader is installable with pip though you may need some
support getting it set up and configured.

espeak-ng is a fork of espeak and can use speechdispatcher.

Thank you for the additional pointers!  I still need to check out
promising combinations of those approaches, also options for MBROLA
(which is not free, but applies a custom AGPL-3.0-but-not-be-sold
license to the voices).  ADRIANE is certainly fascinating.

Best wishes

Re: Suggestions for Text-To-Speech (TTS) from Org sources?

[Jens Lechtenboerger]

Dear all,

some time ago I asked for suggestions concerning Text-To-Speech
(TTS) from Org sources.  Thank you to everyone who provided
suggestions!  In case you are interested, you can listen to sample
results at [1].

Briefly, Emacspeak, espeak-ng, and festival are not good enough for
my purposes.  Maybe I'm missing relevant backend options.  IMHO,
Coqui-AI TTS [2] and Microsoft SpeechT5 [3] are far superior.

Best wishes
Jens

espeak-ng likes to have speechdispatcher on a system and festival likes to
have language-specific voices on it to use.
fenrir which you didn't mention runs in user land and has no kernel
dependencies.

Does this improve the quality of the generated speech?

Indeed.  Which one(s) do you recommend?  I tried
voice_cmu_us_slt_arctic_hts and the mbrola us voices.

I briefly tried that but failed.  Also, I was under the impression
that fenrir does produce speech by itself but relies on some TTS
implementation like espeak.  Is that wrong?
