Hello, Cc-ing debian-accessibility at least for information.

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.

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. Samuel
