On the new site just opened at the CosmoCaixa of Barcelona called Flash, there is a new installation based on MTG's KaleiVoiceCope technology. This new site, designed by Javier Mariscal, aims at developing scientific thinking among kids by promoting experimentation, reasoning and communication. The installation "La meva veu fa ones" (my voice makes waves) is one of the five installations of Flash.
KaleiVoiceCope is the name of a real-time voice transformation technology where an input voice is analyzed in the spectral domain, some spectral descriptors are extracted from it and based on a set of parameters, a new voice is generated changing the timbre, the amplitude, the pitch, and other spectral and physical characteristics. This transformation allows a wide range of possibilities, for instance, changing the gender of a voice from a male to a woman or transforming a teenager to an old woman but also more exotic transformations are possible like robotizing the voice, converting the voice for using it in a cartoon character or giving the voice an alien character as it was taken from a science fiction film.
