Voicepacks installation on Viomi SE

[rufik]

Viomi SE on release 2023.01.0. I have generated voicepack using this generator, got pl.pkg (polish lang) package. Then I hosted file on https://www.file.io, put link and pl lang code (hash left empty), pressed "Set voice pack" and...nothing happend.
Does this feature work on Viomi SE? Or is there a way to install voice manually?

Hi,
I manually replaced "/usr/share/audio/english" wav files, the robot still think it speaks english while it speaks french to me.

cd /mnt/UDISK/Download
ls # make sure you don't have any .wav file in here, also you can clean up some _tmp files that may be left when trying to install voicepacks through the ui
wget https://builder.dontvacuum.me/pkg/voice/viomi/v6/[languagecode].zip
unzip [languagecode].zip 
mv *.wav /usr/share/audio/english
rm *.wav

That isn't persistent on factory reset
