Hello,

Cc-ing debian-accessibility at least for information.

Roland Clobus, le mar. 19 nov. 2024 12:31:15 +0100, a ecrit:

The most striking recording is at step 2:6:1 https://openqa.debian.net/tests/325775/file/bootwalk_2:6:1-captured.wav
which is about 5 minutes long and lists 78 language options.

Yes. One can use arrow keys instead to quickly go over the list.

* Are all these languages supported by the speech generators?

I don't remember if that's 100% the case, in my memory it is at least
very largely covered.

(I've noticed e.g. 'Chinese letter - Chinese letter' being spoken
at 1:00) -> i.e. should the list of languages be reduced for this
specific variant of the installer, because the speech module cannot
read it?

Ideally that could be implemented in localechooser, by looking at the
list of voices in espeak to filter the list.

* Could a different font be used to show the UTF-8 characters, similar to
the text installer?

For the screen reader to work, we have to use the linux console, not
an fbterm. So we are limited to the linux console capability, and thus
cannot display everything at the same time. In practice this is not a
problem because the speech is correct, and the font is switched once a
language is selected.

* The spoken text 'Prompt. For help' does not speak the most important bit, i.e. that the question mark will show the help text

This is

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=690343

forwarded upstream

https://github.com/espeak-ng/espeak-ng/issues/150

* Nowadays newer TTS voices exist that speak a more natural language (e.g. piper https://rhasspy.github.io/piper-samples/), could this be used instead?

The problem is the size. espeak-ng supports a very wide range of
languages with a quite small disk footprint. Piper etc. (we had mbrola
already for a long time) take a *lot* of space. We have packages ready
for including e.g. mbrola voices, but we cannot really include them on
the default images, it's rather for specialized images.

Ideally that could be implemented in localechooser, by looking at the
list of voices in espeak to filter the list.

The next screen typically works fine, so there appears no need for removing some languages from this list.

However, could localechooser use a pre-rendered pronunciation for the language-selection question (activated only when espeak is active)?
E.g.:
# Prerendering of the language file:
echo "Ελληνικά" | espeak-ng -x -v el
# Then the line would become "28: Greek - [[,elinik'a]]"

That'd be complex: espeakup just gets the whole text, it doesn't know
what piece is in which language.

With no upstream activity since 2016, should the text in the installer be changed?

That's a possibility, but the bug really wants to be fixed by somebody
at some point, because such prompts do happen here and there.

Piper has a MIT license and the voices appear to be less restrictive, but I didn't look at it too deeply.

Regarding size: perhaps the netinst image cannot handle the growth, but e.g. a GNOME live image (already at 4GB) can have a bit more.

But it's not just "a bit". Look at the size per language of piper. We
cannot just add a GB of voices for the various languages that d-i
supports.

Or there could even be an a11y live image (or are there already Debian derivatives that handle this?)

Some derivatives do this, yes.
