Voiceless fricatives

[hmwhite2]

Hi there, I’ve come across some cases where REAPER identifies GCIs during voiceless fricatives. Do you have any suggestions about what may be happening here. I can share the wav file. Thanks!

If I remember correctly, the program places dummy pitch marks at constant hop size in unvoiced regions as well. The output file should include separate information on whether the pitch mark is voiced or not.
