Description

As reported by Stepan Novotny on https://bugs.debian.org/1101681

Steps to reproduce

spd-say -o espeak-ng-mbrola 'Testing testing 1 2 3'

Obtained behavior

This fails to use the default (mbrola) voice

Expected behavior

This should select an mbrola voice (according to language etc.)

Behavior information

Running spd-say -o espeak-ng-mbrola -y mb-us1 'Testing testing 1 2 3' does get an mbrola voice.

I tried adding voice configuraiton to /etc/speech-dispatcher/modules/espeak-ng-mbrola.conf

   VoiceFileDependency "/usr/share/mbrola/$VOICE/$VOICE"
   VoiceFileDependency "/usr/lib/x86_64-linux-gnu/espeak-ng-data/voices/mb/mb-$VOICE"
   AddVoice "en-us" "FEMALE1" "us1"
   AddVoice "en-us" "MALE1" "us2"
   DefaultVoice "us1"

The above paramters are all ignored.

Distribution

Debian 13

Version of Speech-dispatcher

0.12.0

Contributor guide

Research direction
Investigate how spd say selects default voice when no voice is specified. Trace the configuration loading for espeak ng mbrola module, specifically the AddVoice and DefaultVoice directives, and understand why they are ignored.
