Are there historical origins of “robotic” voices seen in earlier sci fi movies?

While today text to speech technology gets so advanced that synthetic voices come quite close to human ones, during my childhood I got quite inspired by “robotic” mechanical voices in Hollywood sci fi movies of that time.

Now, my question is – was there an original TTS technology which gave input to those movies, or not?

Movies&TV Tour Display Bug [migrated]

In the “Welcome to STack Exchange” (MOvies&TV) opening page for the TOUR, you cannot see the full questions, or answers. It is a weird error to already run into on my first moments on the site & made reading or understanding this introduction page(s) totally confusing especially since I’m just trying to figure out what this site is.enter image description here
Does anyone know who I notify about this bug in the site?
