REPORT alovitt:rr07-05/IDIAP Truncation Confusion Patterns in Onset Consonants Lovitt, Andrew EXTERNAL http://publications.idiap.ch/attachments/reports/2007/alovitt-idiap-rr-07-05.pdf PUBLIC Idiap-RR-05-2007 2007 IDIAP Submitted for publication Confusion matrices and truncation experiments have long been a part of psychoacoustic experimentation. However confusion matrices are seldom used to analyze truncation experiments. A truncation experiment was conducted and the confusion patterns were analyzed for 6 consonant-vowels (CVs). The confusion patterns show significant structure as the CV is truncated from the onset of the consonant. These confusions show correlations with both articulatory, acoustic features, and other related CVs. These confusions patterns are shown and explored as they relate to human speech recognition.
