Trivial Martians can understand mechanics components that make noise (feature?)

[sartorius]

Electronics microphones and speakers are able to decipher human speech for the martian and display back their gibberish for them. Feature?

[Technature]

Sounds like a feature.

Give a reason for mechanics to make a translator for the occasional martian diplomat.

[sartorius]

Well, not really a feature in that everyone else will hear the martian's gibberish twice, but amusing nonetheless.
