Change TTS model

[JuanJose2325]

Hello, this is my first time here, and I would like to ask a question. I hope this is the right place.

I have OVOS installed on my Raspberry Pi 4, and I would like to change the voice model to one that is in Spanish.

I tried everything, but I didn't get it. I don't even know which voice plugin is being used, as both mimic3 and piper have the ‘apope_low’ voice model with different names, but they sound the same.

I tried to look at ‘.config/mycroft/mycroft.conf’, but for some reason always rebooting the raspberry pi deletes its content, and only the ‘PHAL’ part remains:
{
‘PHAL": {
ovos-PHAL-plugin-wifi-setup": { “ovos-PHAL-plugin-wifi-setup”: {
first_boot": { “first_boot”: false
}
}
}

I tried to install three different OVOS images (the latest multilingual version, the preconfigured English one and the preconfigured Spanish one), and all of them on first boot failed trying to start ‘ovos-listener.service’. The only one that worked was the Spanish preconfigured one, once almost all the contents of ‘.config/mycroft/mycroft.conf’ were deleted, as I mentioned before.

In advance, thank you very much for the help.
