Add an option to make "ttsSpeak" blocking

I tried to make a voice menu using ttsSpeak and recognizeSpeech, however since 
ttsSpeak seems to be non-blocking it's voice was recognized too. 

I wrote a function that blocks until ttsSpeak is done but I would prefer an 
option that does that for me.

I have the same problem. How did you block ttsSpeak? Thanks

It's just a quick & dirty solution. I made a function "say()" that first calls 
ttsSpeak() and than calls time.sleep(0.5) in while ttsIsSpeaking() is true. HTH
