If you leave it as a stereo file and split by silence you'll get a sequence of smaller files in play order, divided up whenever neither person is talking. So essentially both001.wav both002.wav both003.wav (for that your sox command is going to have to contain: "both%3n.wav" I think, though you might need %5n or %7n or something if there's going to be a huge number of these files created). Most of these files should only have one person speaking in them, but clearly there's going to be some with both. I'd then run the sox stats effect on each of those files, piping the output into a script/program. Stats tells you the sound level in each channel of a file. You'd need (by experiment, probably) to find out for yourself what the levels are in a file where one or other person is silent. It should then be possible for your script/program to decide if that stereo file contains only the left channel person speaking, or only the right, or both. I would use that info to rename each of the 'both' files, so eg both103.wav could become voice103L.wav or voice103R.wav or voice103B.wav Then you'd have a set of files like voice001L.wav voice002L.wav voice003R.wav voice004L.wav voice005L.wav voice006B.wav voice007L.wav voice008R.wav voice009L.wav ... To listen to just the lefthand person, you'd want to copy the files with "L" and "B" in their names elsewhere, to get: voice001L.wav voice002L.wav voice004L.wav voice005L.wav voice006B.wav voice007L.wav voice009L.wav ... To listen to just the righthand person, you'd want to copy the "R" and "B" files: voice003R.wav voice006B.wav voice008R.wav ... To listen to the whole thing with both people, just listen to the whole 'voice' set of files. Now, if you think about the "just lefthand person" COPY of the voicennnx.wav files, ie: voice001L.wav voice002L.wav voice004L.wav voice005L.wav voice006B.wav voice007L.wav voice009L.wav ... obviously although these files contain all of the left person's contributions to the discussion, the "B" files do also contain the right person interrupting. If that was annoying then ON THIS SET OF COPIED FILES ONLY you could run on each of the B files the command like: sox voice006B.wav voice006L.wav remix 1 to get a left-channel only copy of what was in the B file. So then you'd have voice001L.wav voice002L.wav voice004L.wav voice005L.wav voice006B.wav chunk 6, both people voice006L.wav chunk 6, left person only voice007L.wav voice009L.wav ... and you could delete this copy of the voice006B file if you were sure you didn't need it.

You maybe need to start by using stat or stats to find things out about sound levels in the files. I'm sure in the past I ran some code that chopped a long file into (shall we say) a series of 5-second mini files, then ran stat/stats on each one, to build up a picture of levels all the way through the thing. If background noise is a problem I think you need to clean that up first, perhaps splitting the channels then cleaning them, then perhaps compressing them (ie reducing dynamic range) - I'm not sure - then joining them back into a stereo file. Then again, increasing dynamic range might make the split easier, even if you compress the audio again later. Do you actually have stereo, or double mono? Can any of the sound of the person on left channel be heard on right channel, and vice versa? > another thing i just thought of, is it possible to split on the silence > of > just 1 channel while the file is still stereo? Don't know... but even if it's not, you could split the whole file into L & R then split L into L fragments, and R into R fragments, and doing that you'd find out (from the sizes/lengths of each fragment) where each channel's split points were. You could then (though I don't see how it would help) merge those two lists of split points into one list and apply those to the original stereo file. -- Jeremy Nicoll - my opinions are my own ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot ^ permalink raw reply [flat|nested] 9+ messages in thread

(It looks like using it on single-channel data is easier/better, and it makes sense to do it this way, because the use of time stamps on the original data means that "silence" regions are not deleted from the data, so portions of interest in the two separate channels retain their original alignment relative to each other -- each speech segment can be handled independently of others, and has a unique identifier to keep track of its position in the overall timeline of the original recording. I haven't used Kaldi at all myself, but this approach to speech detection (using a listing of time offsets, while preserving the full content of the original recording) is a pretty common procedure.
