Hello folks
I have been unsuccessfully trying to configure the ATIS speaker to use a
male voice possibly with lower TTS speed to ease understanding.
Irrespective of any settings, running fgfs with option --log-level=info
generates the following in the printout:
AtisSpeaker voice is
/usr/share/games/flightgear/ATC/cstr_uk_female-1.0.htsvoice
I have tested the default aircraft in several airports including KSFO,
KRHV and LFPG and obtained similar results. Configuration information
follows.
I have FlightGear 3.4.0 installed from the package manager of a Kubuntu
15.10, running on a Dell Latitude E7440 laptop with Intel HDA sound and
Intel HD Graphics 4400 cards and 16 GB of RAM.
Festival is installed along with required voices,
festival> (print (mapcar (lambda (pair) (car pair)) voice-locations))
(en1_mbrola us2_mbrola kal_diphone rab_diphone don_diphone)
and it works, i.e. the following command does produce speech.
$ echo "Flight Gear" | festival --tts --language english
Obviously I run festival server (option --server) before running fgfs.
I have modified the <voices> section of my $FG_ROOT/preferences.xml to
use voice_us2_mbrola throughout:
<voice type="bool">true</voice>
<voices>
<host type="string" write="n">localhost</host>
<port type="string" write="n">1314</port>
<enabled type="bool">true</enabled>

<volume type="double">1.0</volume>
<pitch type="double">100.0</pitch>

<festival type="bool">true</festival>
<htsvoice type="string">cmu_us_arctic_slt.htsvoice</htsvoice>
</voice>
</voices>
These settings affect the voice reading the welcome message but not the
ATIS speaker which remains set to the aforementioned female voice.
Lastly, I have tried to set the /sim/atis/voice property to something
else via:
--prop:/sim/atis/voice=cmu_us_arctic_slt.htsvoice
but that hasn't changed the ATIS speaker voice either.
