An exception is thrown while running the LongTextAligner demo in SpeechMarker:377, as sometimes the signal is DataStartSignal.
I tested a solution in which I do the following:
else if (next instanceof DataStartSignal) {
sendToQueue(next);
continue;
} ...
And it seems to solve the problem, however not sure if this is the best way to solve this.
thank you for the report, we'll take a look on it.
Fixed in trunk now, thanks you for the report
