I am using a D1 Mini with a DFPlayer Mini for audio announcements. This is my ESP Home setup:

# Enable fallback hotspot (captive portal) in case wifi connection fails

I used this text to speach site to create the announcements which are saved in mp3 format and placed on a micro SD card in the DF-Player module.
The sounds are then played in automations using:
service: esphome.d1_mini_speaker_dfplayer_play
data:
file: 1
I’ve seated the DFPlayer above the D1 Mini as shown in the pictures below:
This makes a very compact and cheap audio announcer.
