Hi,

I just installed the recent Pd-extended (0.43.4) and having problems adding new externals. I tried adding a new path under Preferences, but Pd doesn't seem to recognize the sub-folders. However, if I take out the externals from their subfolders and put all external files under one folder - Pd seems to recognize them.

Is this how it should work? Is there anything I could do to help Pd-extended scan through subfolders? Having all external files in the same library is quite messy.

Thanks,

Hi,

I’m trying to figure out how to go about using Pd to design a procedure for differentiating between a single-voice speech and a multiple-voice conversation in which voices overlap. In other words – the moment of overlap is what I’m interested at. I want to be able to listen to a vocal conversation between two people, and detect when voices collide / overlap.

I guess that spectral-wise there’s a major difference between a speech-based conversation with no overlaps compared with a conversation with speech overlaps, so perhaps one direction to look at is detecting sudden spectral changes?

Any thoughts / ideas / pointers for achieving this are very welcome!

Thanks,
K

any ideas?

As a start, the tool should be able to detect human speech activity within an indoor environment with minimal background noise - say a gallery, an office, etc.
The indoor environment may occasionally include some short mechanical sounds which may be louder than normal/standard human speech.

thanks for all replies.

before delving into detecting speech overlaps, i think i should try building a simple patch for speech and non-speech activity detection. can anyone share a patch that does that? or is there a Pd external for voice activity detection?

how do you get the autocorrelation of the spectrum? is there a Pd object for doing this?

anyone?
