Select piper voice in script

Configuration
1

Trying to get a “start” phrase going for voice control. I have it working but the voice used is different than the one used in my voice assistant.
I have this:

        service: tts.speak
        data:
          cache: "false"
          media_player_entity_id: media_player.google_home_mini
          message: Yes, Scott?
          entity_id: tts.piper

Is there a way to select the voice in that?
