Speak node isn't working

[ljmwaugh]

I have configured the TJBot credentials and I have other nodes working (Listening). I know that my speaker works, I can use aplay to play a wav file to the speaker after I stop node-red. I see these lines in the console

I can use the IBM Watson Text to Speech and Play Audio nodes and they work also.
I'm running Raspbian Jessie
