Last week I started teaching a Speech Signal Processing course. This promises to be a fun course for me, since it mixes DSP and human speech production, both topics I’m very interested in. I keep track of links relevant to this course here. The latest link I’ve added to this list is a link to SPAN, the Speech Production and Articulation Knowledge Group at USC. They have fascinating movies showing human speech production as it happens. The movies were made using USC’s high-speed MRI technique. There are several movies on the SPAN home page, and for more click on Videos.
A couple of notes on viewing the SPAN videos. First, to see a video of a particular sound being produced, select the sound and then select the speaker (American or Indian English speaker). Second, on one computer I had problems viewing the videos from Firefox, however they worked fine from IE. So if you’re having problems with viewing try switching browsers (or let me know if you have a better explanation as to why the Quicktime plugin works OK on the home page but not the videos page).
