Is there a way to change the pitch of mycroft’s voice? I am using it in a setup where a need a deeper voice.
practically speaking no. Mimic1 has some options but probably not to the extent you may be looking for. You’d probably want to find a TTS voice that suits your needs and then use that service instead.
What options does mimic 1 have?
