Dreamcard script problem

[Eric Chatonet]

Hi DOug,

If text to speech is not available on the current system, the text-to- 
speech commands set the result function to an error message.
And we may think that's the problem.
So, you could try something like:

put revSpeechVoices() into tVoices
if it = empty then answer error "No computer's text-to-speech  
capability!"
else etc.

or

revSpeak "All is well."
if the result <> empty then answer the result.

Managing errors is one of the most important things in any software ,-)

Best regards from Paris,

Eric Chatonet.
