Walter Daems submitted the SpeLaTeX package. Version: 0.9 2024-06-12 License: lppl1.3 Summary description: Create PDF documents with hyperlinks to audiofragments Announcement text:
SpeLaTeX is a new package that tries to improve the accessability of PDF files by equipping the PDF that is generated with LaTeX with hyperlinks to audio files that contain the spoken equivalent of the original text, equations, figures and tables. The spelatex package is a part of SpeLbox, consisting (next to the spelatex package) of an Org-mode exporter (not yet available, will be released soon) and a Perl module SpeL::Wizard that contains a script (spel-wizard.pl) to convert LaTeX constructs (including mathematical equations) into proper language to further convert it to audio files using text-to-speech software/services.
The package’s Catalogue entry can be viewed at https://ctan.org/pkg/spelatex The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/latex/contrib/spelatex/

Spe – Create PDF documents with hyperlinks to audiofragments

This package equips the PDF that is generated with with hyperlinks to audio files that contain the spoken equivalent of the original text, equations, figures and tables.

The audio files can be automatically generated using a Perl-script called spel-wizard.pl (part of the SpeL::Wizard module available on CPAN). This script interfaces with locally installed text-to-speech software or with online available (paying) cloud services to generate the audio files. To this end, the chunks of your text are parsed and translated to “natural language”.

Spe is babel-enabled such that your text is read with the correct pronunciation corresponding to your language. So far, it provides the languages English and Dutch, but it will be extended in the future.

You can package your PDF together with the audio-files (in your favorite archive format) and make it available to your users, such that the only requirements to read your text and listen to the audio are a suited PDF reader and media player. Not all readers and players work. Working readers are: okular, acrobat reader, pdfxchange viewer. Working media players are: SoX, totem, vlc.

The package is part of the SpeLbox package, consisting of

  • an Emacs Org-mode exporter, called ox-spelatex (under development, will be released later),
  • the spelatex package itself,
  • a perl script spel-wizard.pl available from CPAN in the SpeL::Wizard module that converts text to speech (doing the magic, parsing your equations).

The package also functions without the Org-Mode exporter, the latter just being there to make use more convenient.

For the text-to-speech conversion, one can use free options (festival, balabolka, ...) or paying services (e.g. AWS polly).
