Mistake in docs

[michalelektryk]

Steps to reproduce

open API.markdown

Expected behavior

Tell us what should happen
silence.detect_(non)silent() should have different descriptions

Actual behavior

Tell us what happens instead
silence.detect_silence()
Returns a list of all silent sections
silence.detect_nonsilent()
Returns a list of all silent sections

If it indeed is supossed to return silent sections in both cases then I'd rephrase docs a bit
