Please help translate my Chinese seal chop (Characters identified: 詩思妮) While on a recent trip to Shenzhen, China, I came across a booth selling Chinese Chops.  I had one made for me.

The artist asked me to write my name down, CECILE, and he made me this chop.  Since he didn't speak English and I don't speak Chinese, he was unable to tell me the meaning of my chop.

Please, can you translate it for me?  Thank you!!
The characters are


  詩思妮


You can hear them at Google translate (ignore the translation).
