I got this shield for an Arduino: https://www.sparkfun.com/tutorials/302

It works with an ESP32 too. Although, does the ESP32 have its own CODEC? The datasheet confuses me:

When one or both of the I2S interfaces are configured in the master mode, the master clock can be output to the
external DAC/CODEC.

Do I need to use something like the ES8388? I need ESP32/8266 access point (AP) function and a way to emit a bell sound to speakers (with their own amp).

The ESP32 microcontroller itself does not have a built-in audio codec. The reference to the master clock being output to an external DAC/CODEC in the datasheet indicates that you can use the ESP32's I2S interface to communicate with an external audio codec chip, such as the ES8388 mentioned.
