A Potential bug in the way start and end are counted in the Java codebase.

For the line

Let's consider 16000 hz, speechPadSamples = 10 and audio detected in the first call to the apply method.

In the currentSample it add the windowSizeSamples.
so currentSample = 512

That means if the audio is identified as speech.
speechStart = (int) (currentSample - speechPadSamples)

i.e
speechStart = 512 - 10 = 502

but it should be 0.
