To use MBROLA voices you have to install:
1. MBROLA synthesizer:
sudo apt-get install mbrola
2. MBROLA voices (i.e. voice database files) e.g.:
sudo apt-get install mbrola-de4
Note, that not all MBROLA voices, which are configured in eSpeak NG, can be
installed as standard packages. More MBROLA voices can be downloaded from here:
https://github.com/numediart/MBROLA-voices/
Files located in .../espeak-ng-data/voices/mb are actually mapping files
between eSpeak NG phoneme names (phonemes) and phonemes used in MBROLA
voice databases. As described here: https://github.com/espeak-ng/espeak-
ng/blob/master/docs/mbrola.md

Title:
espeak-ng cannot load mbrola language files
Status in espeak-ng package in Ubuntu:
New
Bug description:
I tried using all of the mbrola files named by espeak-ng --voices=de :
Pty Language Age/Gender VoiceName File Other
Languages
5 de --/M German gmw/de
6 de --/F german-mbrola-1mb/mb-de1
6 de --/M german-mbrola-2mb/mb-de2
6 de --/F german-mbrola-3mb/mb-de3
6 de --/M german-mbrola-4mb/mb-de4
6 de --/M german-mbrola-6mb/mb-de6
7 de --/F german-mbrola-5mb/mb-de5
7 de --/F german-mbrola-7mb/mb-de7
espeak-ng -vmb-de1 "Test"
gives me:
mbrola: FATAL ERROR : cannot find file /usr/share/mbrola/de1/de1 !
mbrowrap error: mbrola closed stderr and did not exit
Error: Could not load the specified mbrola voice file.
It does speak, though, seemingly using a default voice.
/usr/share/mbrola does not exist.
The files actually seem to reside in
/usr/lib/x86_64-linux-gnu/espeak-ng-data/voices/mb
I doubt that I can solve this via a simple symbolic link because
seemingly the expected directory structure is different: all mbrola
files are in the mb directory; there are no subdirectories like
/de/de1 or similar.
