Running Android Voices in Linux?

[Linux for blind general discussion]

No clue about actually using the voices, but a little Googling would
suggest .apk files are just zip archives with a different file
extension.

So the first thing to try might be:

mv voice.apk voice.zip
unzip voice.zip

to extract the contents of the package.

That said, Googling also suggest some .apk files are encrypted, though
apparently, decoding apk files so the above works can be done with
apktool.
