    The yellow cable goes to a speaker and the other to power source

    Sir . . . . . . . 'po man on a . . . . . . Tightbudget . . . . .


    That all depends upon the numbers that you feed back to us that are on that 14 pin IC chip.'
    You provided a good close up but I am still not seeing its top numbers / I.D. .
    If the audio playback is just a tune it is probably from a preprogrammed digital RAM mask deep with in the unit and with no access for modification.

    HOWEVER if it is a voice recording chip, like you can find being used on premium greeting cards, that's certainly having a possibility for re recording.
    They use a small flat piezo speaker which gives some intelligibility, but amazingly it is also used as a microphone during recording.
    with an even more amazing audio response.

    Thasssssit. . . . . .

    My guess is those are in house manufacturers codes and won't be useful for tracking down the origin of that chip.
