This is Priority.TEXT, so the first message is supposed to be
interrupted and discarded and you should start hearing the
second message ("world") after 0.1 seconds.

Of course in practice, the delay can be longer than 0.1
seconds considering the latencies of stop and new
playback, which depends on the synthesizer,
audio system used etc.

If IBMTTS doesn't do this, it it can have quite bad
effects for the end user experience.

The next step would be to enable module debugging
and try to see where the delay is. Does the module
get a STOP command from the server? Does it react
on it quickly enough?
