I didn't know whether to laugh or scream when I heard this, so I did them both at the same time. It reminded me of nothing more than Rusty in Orchestraville, which I uploaded on my YouTube channel quite a long time ago (see below).
Peter the Piano is the only instrument that DOESN'T speak in this horrific method of child musical indoctrination. The others "speak" through the miracle of Sonovox, a method which pipes musical sounds directly into the larynx via a small speaker. The person is force-fed the sound, so to speak, then kind of verbally vomits it up. Thus the clarinet or flute or violin or whatever appears to "speak". It doesn't, of course - it sounds stringy and miserable, not to mention creepy. But back in the 1940s, it was the wonder of the ages.
There is a newer, much hipper version of this called a talk box, but I think it's the same deal, the sound of the instrument magically vomited up. Or projected, or broadcast, or whatever it is. The talking piano is much more scary, its "voice" freaky beyond belief. It has to be programmed in a sort of elaborate way. I don't know why anyone would ever want to do this. The piano is a piece of furniture designed to hold up flower vases and look decorative. Anything else is overkill.
