Cannt get Mycroft to use Mimic3

Hello everyone,

so I installed the mimic3 plugin for mycroft on my instance and changed the config according to the instructions on github but mycroft still speaks with the default mimic voice and i cant find the reason why it shouldn’t work.

My setup is a Raspberry Pi 4 8GB with Raspberry Pi OS Lite 64bit (Release date: September 22nd 2022)
I only installed the linux mycroft version and paired it with the website befor I installed mimic3

This is my config.

and I verfied with “mycroft-pip list” that the plugin is installed.

Do you see any errors in /var/log/mycroft/audio.log when starting up?

I getting this error when starting

I had a similar problem. I forget what exactly I traced it to, but it was a problem with how it’s invoking the download process to fetch the voice on first use. The solution for me was to go manually download the voice myself via SSH. Did something like this:

cd mycroft-core
source .venv/bin/activate
./.venv/bin/mimic3-download en_US/cmu-arctic_low

After that I stopped getting the error and mimic3 started working.

Please try upgrading the Mimic 3 package:

pip install --upgrade mycroft-mimic3-tts

Working now. Did it first manually but tested it with a diffrent language with the updated package and that also worked. Thanks for the help.
