Lecture 28 Blog, ECE438 Fall 2010, Prof. Boutin
Friday October 29, 2010 (Week 10) - See Course Outline.
Today we talked about speech signals. After discussing some applications and challenges related to speech processing, we defined the "phoneme" as the basic unit of speech. We described the difference between "voiced" and "unvoiced" phonemes and discussed methods for determining whether a given 5-10 ms block of a sound signal corresponds to an unvoiced or voiced phoneme.
It has come to my attention that some students do not know about the course outline, which lists several references for the different topics we are covering in class, including the relevant pages in the official textbook, whenever appropriate. Some online references are also given. Please check it out!
Relevant Rhea pages:
- speech lecture notes written by one of my students last year
- A student page on digital speech generation
- A student page on speech spectrograms
- A student page describing the difference between male and female voices
