Your Computer As Your Singing Coach

Roland Piquepaille writes "Israeli researchers have developed an electronic ear to coach vibrato technique. Until now, the quality of a vibrato — the pulsating change of pitch in a singer's voice — could only be judged by voice experts. Now, a Tel Aviv University research team 'has successfully managed to train a computer to rate vibrato quality, and has created an application based on biofeedback to help singers improve their technique.' Interestingly, this research could be used for other applications, such as improving automated help centers, where computers could be trained 'to recognize a range of different emotions, such as anger and nervousness.'"

Truly impressive

...every programmer should work with something like this at least once. I did some audio programming work in college, and its a totally different world than the regular web dev stuff I have done, because you're working with the convergence of acoustics and physics with programming. In true signal processing apps, what you are doing has to happen FAST as well, which makes the guys who work in it true wizards, and that's without even considering the subjective recognition stuff that these researchers had to do. Kudos to them.
