Subject: Re: AUDITORY Digest - 18 Jul 2009 (#2009-164) From: Jont Allen <jontalle@xxxxxxxx> Date: Sun, 19 Jul 2009 11:52:09 -0500 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>lots of interesting questions. Look at the following paper, for our best guess: Allen, Jont and Li, Feipeng (2009). Speech perception and cochlear signal processing, IEEE Signal Processing Magazine, Invited: Life-sciences, 26(4), pp 73-77, July There is a preprint pdf and a djvu galley, on line at http://hear.ai.uiuc.edu/wiki/Main/Publications/ Also I suggest you look at: S. A. Phatak, Y. Yoon, D. M. Gooler, and J. B. Allen. Consonant loss profiles for hearing impaired listeners, J. Acoust. Soc. Am., (2008) (Accepted with minor revisions 6/9/09) Again, a pdf is available on the website. Also ck out the "Demos" at http://hear.ai.uiuc.edu/wiki/Files/VideoDemos http://hear.ai.uiuc.edu/wiki/Files/ A detailed resp to your important questions would talk an hour, and the issues you ask about are discussed in the papers, hither and yon. Some of the questions are answered in: Feipeng Li and Jont B. Allen. (2009) Manipulation of Consonants in Natural Speech; which as it says, is "In preparation."
