[Tts-project] Bug#1018075: Default to espeak-ng-mbrola which has no voice?

[Sebastien Bacher]

Package: speech-dispatcher
Version: 0.11.1-3

Hey there,

I don't really know the speech-dispatcher stack but was trying to help 
debugging https://bugzilla.mozilla.org/show_bug.cgi?id=1753637 in firefox

The issue is discussed in 
https://stackoverflow.com/questions/46617366/speechsynthesis-getvoices-not-listing-voices-in-firefox 
with some details, but it seems the problem is that espeak-ng-mbrola is 
the default output and that has no voice?

$ spd-say -O
OUTPUT MODULES
espeak-ng-mbrola
espeak-ng

$ spd-say -o espeak-ng-mbrola -L
                      NAME LANGUAGE                  VARIANT
$

Should espeak-ng be the default?

Thanks,
