Hi, want to share my script how you make a good tts announcement on sonos.

How it works:

• triggered by an automation like this

          - service: script.turn_on
            entity_id: script.jarvis_speak
            data:
              variables:
                mymessage: |
                  {{ state_attr('sensor.notification_message', 'msg') }}
                myplayer: media_player.sonos_bedroom

• the script is using an input_boolean to flip so that one announcement is done at a time, that’s why I have the “jarvis_announcement_wait” boolean
• it uses "input_number.jarvis_<<room>>_volume to be able to adjust the volume per room for the announcements
• it uses a little “ding” sound prior to the announcement
• it uses piper and with trial end error I figured out how many word per minute “ryan” is speaking so that the script ends exactly at the time when the tts announcement has finished in case there are multiple announcements to be made per room
