I'm trying to combine PocketSphinx with the VuforiaSampleDemo app. I have each installed as separate projects in Eclipse running on Ubuntu, which work fine independently.
However, when I try to incorporate PocketSphinx into the other app (Vuforia ImageTargets package) by copying the appropriate code lines and methods across, I get a crash.
It seems the crash occurs when the code executes the line:
recognizer = defaultSetup().setAcousticModel(new File(modelsDir, "hmm/en-us-semi"))
.setDictionary(new File(modelsDir, "dict/cmu07a.dic"))
.setRawLogDir(assetsDir)
.setKeywordThreshold((float) 0.01)
.setSampleRate(16000)
.getRecognizer();
I have copied the assets across from PocketSphinx to the Vuforia app. Can anyone shed any light on this? Thanks.
This is my LogCat output:
