Is it possible to use these cheap sound chips with DCC?

I saw these cheap sound chips on Aliexpress: https://www.aliexpress.com/item/1005003986094059.html

They can record a few seconds of sound, and I kinda thought, would it be possible to hook one of these up to a Lais DCC decoder that I have or similar to play a quick sound?

And you can buy a module here: https://www.aliexpress.com/item/32760347716.html

And here is instructions: https://www.allelectronics.com/mas_asse ... /ME-63.pdf

So you can record and test the chips first in this module I guess, then you take the chip out and solder it to a DCC decoder and a speaker and only use it for playback. So what may be the best way to hook it up to a function pin on a DCC decoder to trigger the sound with the DCC controller? I guess it need much less voltage and stuff at least than what DCC uses.

And yes, I understand this is obviously not as good quality and stuff as a proper DCC sound chip, and can not use multiple sounds and synchronized chuffs etc, but I thought this might be a cheap alternative for just like a locomotive whistle or so and a fun little project since I been been soldering in cheap DCC decoders in my old non DCC ready locomotives.

I doubt a DCC loco decoder would be able to operate the sound chip directly. IMO its highly unlikely a Function output (switched negative to common Positive Blue wire) would work. But a function output could operate either a 12v micro relay and via the relays contact closing operate the sound? Or use a transistor as the switching means.

I don't see them going into 00 scale and below locos, but they definitely would have a use for supplying spot background sounds at points around a layout, or for an overall background soundscape if fitted below a micro layout.

Hm, yeah I thought they could not probably be hooked up directly to a DCC function, any idea how I can try hook it up with a relay or transistor? how the schematic would be? And could a resistor or something be used to lower the voltage from DCC? Cus that's what I done with LEDs before and what's recomended to do.
