Hi guys,

When ever I use the command "Say" in terminal,it says the words I want it to say,but then gives me this error:

MTBEAudioUnitSoundOutput::PropagateProperty Error -10851,

Should I be worried about this?

Processor 2.7 GHz Intel Core i5

Memory 4 GB 1333 MHz DDR3

Graphics AMD Radeon HD 6770M 512 MB

Thanks again,
