My project, Speed Reader, has been approved for the BeagleBoard Sponsored Projects Program. Now I’ll receive a BeagleBoard to prototype a Speech Timescale Modification application for playing audio books. I’m one step closer to building a real application!

Basically, timescale modification of speech is accomplished by first dividing the speech into segments. Then segments are deleted to speed up the speaker rate or segments are repeated to slow down the speaker rate. The two key issues are how to segment the speech and what segments can be deleted or repeated without degrading intelligibility. Speech [...] The first multimedia software project that I’m working on is an application that changes the playback rate of recorded speech, also called time scale modification of digitized speech in the technical literature. Obviously this is more complicated than just playing back digitized speech at a faster or slower rate than it was originally recorded. Doing [...] |
