Experts from the French national center for scientific research CNRS led by Jean-Julien, Ameture introduced the world's first algorithm that can change emotions invested in voice recording.
In experiment took part 109 volunteers. They were asked to read aloud extracts from the book of Haruki Murakami. Next, the researchers developed a program of changing emotional color of the voice. So neutral voice got shades of fear, sadness, or happiness.
The volunteers listened to his own altered voice on the record, but no one was able to detect the substitution. Almost all felt that their voices were not altered or changed. Even scientists have noticed listening to your own voice upgraded emotional status of people.
