Voice transformations

Alta Voce brings to market high-quality software technologies that shape voice in real-time, to improve communication and social relations.

Whether the voice belongs to a person from a customer care centre, or to your vocal assistant, you need it to be intelligible and expressive. Our cutting edge voice processing solutions are driven by advanced research in cognitive neuroscience, focused on how speech and music create emotions.

As you listen to these examples, bear in mind that all of this is
real-time: you could literally pick up the phone, and have Alta Voce transformations such as these kick in, as you speak – no fixed script, no prior learning. Does this spark ideas ? Get in touch !
