Hi. gnome-speech is deprecated since GNOME 3. There is only one reverse dependency left, which is dasher, which also seems abandoned upstream since 2010.
I have no experience with dasher, and can not test it either. It looks like dasher should be removed from the archive. Or does anyone know of an effort to port it to at-spi2 and speech-dispatcher? Does it still work / do anything useful? -- CYa, ⡍⠁⠗⠊⠕
