E-ear measures vibrato
Scientists at Tel Aviv University in Israel have developed an electronic ear to measure a voice's vibrato. Vibrato means the regular changes of height in a tone (in an instrument or singing voice), the 'trembling' of tone height, as it were. Vibrato can make a tone sound warmer.
Song samples of hundreds of students and the evaluations by their tutors have been collected on computers. With mathematical measurements the vibrato styles and quality, as set by tutors, could be correlated. Because of this the computer can now judge the quality of new vibrato voices on its own.
Future Vision by Erwin van Lun on this article
New technology like this can lead to all sorts of new applications. This shows how a coaching brand can develop in the area of singing: we’ll be guided from when we’re a small child and receive coaching without needing an expensive tutor. Another application is in call centers that recognizes emotions in voices and that the scripted text can take into account. Or that, in videos of young new talents, we can find the truly talented people extremely fast. But eventually this is about the automation of listening: brands will be able to understand every detail in a customer’s voice. And for all I know you’ll sing what it is you want.
