Hello ecebloggers,

Today, Monday 05/12/2008 was the last day of the student project presentations and the day of LPC (Linear Predictive Coding). The session chair was Nate Bourgoine (picture below).

After a little confusion in the beginning, Ivan Elhart (in the picture below), CATlab member, opened today’s presentations with Project 25 MATLAB implementation of compression. He explained the standard he tried to implement for speech compression and he compared his results with Praat.

Yuanli Wang (picture below), who we know as the session chair for Wednesday 05/07/2008, used LPC for compression and synthesis of speech. We had a nice demo where we heard his results.

After Yuanli, another member of CATlab presented. Oszkar Palinko (picture below), presented his work on a wireless microphone. He transmitted LPC coefficients to lower the amount of data transmitted over RF.

The honor of closing the student presentations went to Dan Reynolds (picture below). He implemented audio water marking and his presentation was voted for the best student presentation of the class. He also received a nice book as a reward. Congrats Dan!

Here should be a picture of all of us with a satisfied, wide smile after the end of the ECE 992 Speech class. Unfortunately you’ll get just the description of the picture because my camera battery died, but I’m sure you can imagine it. Here’s some help : )))

All pictures from the presentations can be found here.

Have a good one,

Nemanja Memarovic
