#16 Hang after init/speak/shutdown and repeating for 2nd time
I am using freetts/(via jsapi) in a component-based IDE
for building web applications targeted towards
building/home automation/security.
In design mode, I allow actions to be invoked on
components. This requires a start/speak/stop cycle.
When I attempt this the second time the system
appears hung.
I have verified that allocate/deallocate are done in
start/stop methods. Yet I get the hang. Is there
something else I need to close/free?
Following is stack trace...I can send 3 method
(start/speak/stop) code snippet if desired.
voice is being started...
Allocating synthesizers...
Loading voices...
voice is started!
<note: voice is successfully spoken here>
voice is being stopped...
voice is stopped!
<note: speaking hangs on this run>

I definitely think there is a bug here.
Code seems to be hanging in freetts.Voice$1.run() where it is
waiting on an output queue. Thread gets started in here but
never stopped.
I have deallocated synthesizer after speaking voice, yet the
freetts code doesn't shut down.
I have an engineStart/speakVoice/engineStop metaphor going
and stopping the engine ain't doing it.
My start code:
javax.speech.synthesis.Voice kevinHQ = new
javax.speech.synthesis.Voice
("kevin16",
javax.speech.synthesis.Voice.GENDER_DONT_CARE,
javax.speech.synthesis.Voice.AGE_DONT_CARE, null);
SynthesizerModeDesc unlimitedDesc = new
SynthesizerModeDesc
("Unlimited domain FreeTTS Speech Synthesizer
from Sun Labs", null, Locale.US, Boolean.FALSE, null);
synthesizer = Central.createSynthesizer
(unlimitedDesc);
if(synthesizer == null)
{
System.err.println(noSynthesizerMessage
("unlimited domain synthesizer"));
return false;
}
synthesizer.allocate();
synthesizer.getSynthesizerProperties().setVoice
(kevinHQ);
synthesizer.resume();
My speak code:
synthesizer.speakPlainText(words, null);
try
{
synthesizer.waitEngineState
(Synthesizer.QUEUE_EMPTY);
}
catch(InterruptedException x)
{
logger.log(Level.SEVERE, "Got exception using voice",
x);
}
My stop code:
synthesizer.deallocate();
None of my code is present in the stack dump I get. Just
some freetts threads hanging around.
Here is abbreviated/relevant portion of stack dump:

Hi Mike:
So sorry for the long delay in this. The good news is that
I'm taking a look at the problem now. :-) The underlying
problem might be in the JavaSound support, which we do not
have control over. I'm curious if you can try the latest
stuff in CVS, though, to see if that works any better?
Will
