"As for Speers, who still gets nostalgic when he recalls singing the Klingon lullaby “May the Empire Endure” with his son at bedtime, the experiment was a dud. His son is now in high school and doesn’t speak a word of Klingon."Speers, the linguist, puts his skills to work at a company called Multilingua, which writes translation software for more common languages, and also Klingon.
In a similar experiment I "speak-a to Linus, ina da brokena English, so dat he canna learna da' Italian of-a my ancestors", or I "talk with zee Fwench accent, ah, hah, hah ,hah". I am not sure it is working. Every day I myself fight the urge to turn my child raising into a grand sociology experiment. I suppose only an ethics board review and jail time keep me from enacting this dream.
