Story

The parts list for the talking compass is a Micro:bit with its battery pack, an Amp:Bit by Proto-PIC and a speaker. The Microbit is inserted into the Amp:bit and the speaker is connected to the terminals on the Amp:Bit. Just that easy.

You could use a small mono amplifier instead of the Amp:bit, like one from Adafruit.

The software is written in Micropython.

import speech
from microbit import *

compass.calibrate()
while True:
    needle = compass.heading()
    if button_a.was_pressed():
        if needle > 34 and needle < 79:
            speech.say("I am facing north east!")
            display.scroll("NE")
        elif needle > 80 and needle < 124:
            speech.say("I am facing east!")
            display.scroll("E")

            display.scroll("W")
        elif needle > 305 and needle < 326:
            speech.say("I am facing north west!")
            display.scroll("NW")
        else:
            speech.say("I am facing north!")
            display.scroll("N")
