Consider orang-utans.
In all the worlds graced by their presence, it is suspected that they  
can talk but choose not to do so in case humans put them to work,  
possibly in the television industry. In fact they can talk. It's just  
that they talk in Orang-utan. Humans are only capable of listening in  
Bewilderment.
