Our vision

Voice is one of the most important communication tools. It can be used to infer personality traits, mental states, emotions or intentions like sarcasm. For listeners, it’s like a compass to navigate their social world. We have been studying voices and person perception for years, and now we’re making a tool available for all of you. It’s simple, you can record your own voice and get feedback from our community, or you can simply assess other people voice.
