* 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 On Mon, Sep 11, 2023 at 4:02 AM Christian Thäter wrote: > On Sun, 10 Sep 2023 16:39:26 +0200 > Jens Lechtenboerger wrote: > > > On 2023-09-10, Ihor Radchenko wrote: > > > > > Jens Lechtenboerger writes: > > > > > >> does someone here produce audio via Text-To-Speech (TTS) from Org > > >> sources?
