Mimic3 Error

[MatthewJSalerno]

Thank you for putting the effort into splitting this out.

Debian 11 64-bit Raspberry Pi 4 (8gb)

I've gotten the stack up and running but when I switch from mimic to mimic3 and any audio response gets generated, I get an error.

I've tried $ mycroft-config set tts.module mimic3_tts_plug

As well as the example config from the mimic3 GitHub page

I've only started tinkering with this and I'll post any progress I make, I'm curious if anyone has gotten this working.

Thanks

Resolved due to an error in my config. Here's a working config.

  "max_allowed_core_version": 21.2,
  "hotwords": {
    "hey mycroft": {
      "module": "ovos-precise-lite",

      "sensitivity": 0.5,

    }
  },

  }
}

Awesome :+1:

I did find an issue when I restarted everything (docker-compose down/up). If the voices aren't cached the mimic3 will fail on startup.

If I log into the container and execute: mimic3 --voice en_US/vctk_low#p283 "test" > /tmp/output.wav it will download the voice data to /home/mycroft/.local/share/mycroft/mimic3/voices/, which gets clobbered on restart. It looks like it needs a volume like Precise-lite with a local clone of https://github.com/MycroftAI/mimic3-voices

@MatthewJSalerno thanks for flagging this, could you please open a new issue with this?

[goldyfruit]

@MatthewJSalerno I created the issue and pushed a change, let me know in #30 if it fixed your issue.

[MatthewJSalerno]

I created https://github.com/smartgic/docker-mycroft/issues/31 which is pretty damn close to the latest commit. I need to clean up my system and then I'll try it out. Thanks.
