espeak-ng cannot load mbrola language files

[zapyon]

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-1 mb/mb-de1
 6 de --/M german-mbrola-2 mb/mb-de2
 6 de --/F german-mbrola-3 mb/mb-de3
 6 de --/M german-mbrola-4 mb/mb-de4
 6 de --/M german-mbrola-6 mb/mb-de6
 7 de --/F german-mbrola-5 mb/mb-de5
 7 de --/F german-mbrola-7 mb/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.

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
