So you'd have the track pieces labeled with the sound they make and line them up to pronounce various words, even sentences for larger kits.

The engine has an air compressor or a container of pre- compressed air that it blows into the various resonant chamber as it passes over them.

I'm still trying to find the science museum exhibit that featured these mouth shapes you could put an air tube up to so they'd make talking sounds. Sort of hard to explain without showing that.

I wonder whether, using blocks which speak phonics, a toddler unable to speak could make the blocks say words by lining them up and pushing a "talk" button.
