Dear List, I am doing a project involving phonological processing using auditory words and pseudowords. I am trying to find a good non-phonological control stimulus that does not contain recognizable phonemes, but still has similar characteristics and complexity to speech. An ideal solution would be some kind of filtering or distortion that I could apply to my existing word stimuli so that each word is matched with its own control, but I would be open to independently generated stimuli as well. I have tried playing the words backwards, and have experimented a little with band pass filtering, but the results still end up sounding too "phonological." Does anyone know of better options? Since we're doing a matching task, each control stimulus would also have to be unique sounding enough for our subjects to discriminate. Thank you in advance, Livia King
