Hi @aviadlevy,

You can do this by setting the tts_platform parameter value to another TTS platform you have installed on your Home Assistant instance.

Wow! I guess I somehow missed that from the documentation.

Thanks for the quick response

It wasn't explained in the documentation so it's not your fault for not knowing. Thank you for raising the issue, I'll add a comment to make it clearer 👍
