Our Vision: Collective AI®

SoundHound’s Collective AI architecture allows for contribution and collaboration among developers where they can extend the functionality of existing Artificial Intelligence domains without needing to access (or even fully understand) them. This results in a Collective AI with comprehensive knowledge, that is always learning, is crowdsourced to domain experts, and is bigger than the sum of its parts.
