RapidEars Return Segments

[Matt]

I cannot get RapidEars to return segments, or segment times. It seems that all four of the appropriate delegate methods in OpenEarsEventsObserver+RapidEars.h cause the app to crash. Tested this in the stock sample app with RapidEars added.

I have [self.pocketsphinxController setReturnSegments:YES]; and implemented rapidEarsDidDetectLiveSpeechAsWordArray:andScoreArray:

Without the method implementation, the app doesn’t crash, but obviously I cannot get the results. Anything I am doing wrong?

Here is the relevant output for the case mentioned above:

OK, this appears to be fixed in the upcoming next version of RapidEars, thank you for the report.
