Below are some links to demonstrations of the vocoder in pop music. The vocoder is an instrument which splits the input speech into source and filter parameters. In "normal" usage, the original speech signal is reconstructed by generating an artificial source signal (pulse train or white noise, for voiced and voiceless speech sounds, respectively). This source signal is
then led through a filter bank which reconstructs the original filter features.
In pop music, the source signal is replaced by a different signal, from a musical instrument. The filter features are then assigned to the instrument signal. The resulting effect is that of a "talking" instrument.
Several readers have pointed out that the audio demonstrations on this page were not vocoded at all. We apologize for the confusion, and refrain from listing demonstrations here before we've improved our homework for this page. Meanwhile, you can browse the hyperlinks below for true vocoder demonstrations.
