Week 8: Mon. Chap. 7, p 220-236. Do 7.8 - 7.10 on your own. We will use pezdemo.m in class Wed. Download from Oncourse, m-code Cool MatLab Demo site (with Pole-zer0) .
Feb. 27, We will meet in in Ballentine 107 STC cluster. Readings are: #1Ingle & #2polezero on Oncourse->Resources->readings.

Week 9: Mon: Chap 8 -> p.267. Before next Wed. class, on the CDRom, do Examples 8.3 & 8.5 and Exercise 8.3 Look at the first Demo movie with one pole. Wed: Chap. 8 ->p 293. Before Monday class after spring break, on the CDRom, do Exercises 8.7 & 8.10. do IIR Filtering Demo and Z to Freq. Demo.

Week 10: Mon: Chap. 8, Readings # 2 & #3 on Oncourse.
Wed March 19 : We will meet in in Ballentine 107 STC cluster for some hands-on lab time. Reading #4 on Oncourse.

Week 11: Guest Lecturer 2008, Michael Brady. Mon: Klatt Synthesizer. Reading (available through IU libraries or when on IU network, is: "Klatt, D.H. (1980). Software for cascade/parallel formant synthesizer. J. Acoust. Soc. Am., 67, 971-995". Click here for the code for the Fortan subroutines for PARCOE.FOR and COEWAV.FOR. Check out this cool speech synthesis article in Scientific American. Wed: Rest Klatt. Good Speech Analysis site for MatLab.

Week 12: Mon: Mostly we skip Chap. 9 in book. DFT in Reading #5 & #6. Lecture will include dfs.m, idfs.m and other code found in Oncourse->Resources->m-code-dkp-> Wed: Topics include FFT and Spectrograms. Reading # 7 and Chap. 9, 355-376. For Class, bring print out of specdkp.m and spectgr.m. Cool Psychophyscis MatLab Toolbox.

Week 13: Mon. April 7 : We will meet in in Ballentine 107 STC cluster to use COLEA at the end of class. LPC readings #8 & #9. Web Site for Colea. Download and unzip Colea somewhere for lab.

Wed: We'll begin with overview of spectrograms from Week 12 (bring printouts) Start lectures on cochlear implants. For a nice lecture on the anatomy of the ear by Jae Hee Lee, check this power point file: jaeheeearanatomy.ppt. Print and read Dorman and Wilson, 2004, Design and Function of Cochlear Implants, Am. Scientist, 2004, vol. 92, no5, pp. 436-445 (through IU liabrary) . Also start Loizou reading: Web site for Loizou's To Cochlear Implants Lab and paper. Click here to get .pdf file for Loizou's figures.

Week 14: Mon: Print your own copy of: Baskent & Shannon (2003) "Speech recognition under conditions of frequency-place compression and expansion", JASA 113, 2064-2076 from

Wed: April 7 : We will meet in in Ballentine 107 STC cluster for hands-on demos. First is for cochlear implants: from Oncourse->Resources->ASSFIN, get Melcoch.m & dilmbin.mat. Then we will start Straight. First read, Click here for tutorial reading 2006, Hideki Kawahara, STRAIGHT, Exploration of the other aspect of VOCODER: Perceptually isomorphic decomposition of speech sounds, Acoustic Science and Technology, Vol.27, No.6, (2006). Note we are saving morphing for next week. There is a Straight demo for today. First, download STRAIGHT(V40_006 (you must be on or IUVPN) and unzip it. Also, download the 4 files in Oncourse->Resources->straight-demo, making straightpath.m work for your environment.

Week 15: Mon: Primary lecture on Straight. Click here for main1999 reading, Kawahara, H. (1999). "Restructuring speech representations using a pitch-adaptive time-frequency smoothing ..", Speech Communication 27, 187-207.

Wed. April 23 : We will meet in in Ballentine 107 STC cluster for hands-on demos. For Straight demos, Click here for a manual. You need tellsam.wav downloaded from Oncourse-Resource->spec. Next we will discuss and demonstrate morphing in class. You should print and read Hisami Matsui, Hideki Kawahara: Investigation of Emotionally Morphed Speech Perception and its Structure Using a High Quality Speech Manipulation System, Prod. Eurospeech'03, pp.2113-2116 2003. on the Straight website. Download and unzip the morphing code and documentation from the STRAIGHT website. Also, download and unzip the file morphing zip in Oncourse->Resources->ASSFIN.
