MMI speech like dodgy 80s speech synthesizer

[BlingPiece]

Just bought a brand new Audi q3 sportback, and whilst she’s a thing of beauty, the mmi voice sounds like an old computer speech synthesizer from the 80s. 
 

before I bought it I test drove a Mercedes a class and this was streets ahead.

is there any way to change or update it? 
 

cheers
