This project intends to develop a software platform that enables in a smartphone / tablet functionality of the virtual assistant, through interaction with a 3D anthropomorphic avatar that will be able to assume the most appropriate form to the second field of use and preferences of the person it will have installed on your device. The interaction will be vocal will be enabled by speech recognition functionality present in the reference architectures, iOS, and Android, and rendered functional algorithms for semantic search and natural language processing, will include activities necessary to integrate software libraries developed by third parts that may be necessary (for example, those for the realization of the avatar 3D). This platform will be designed and developed to be easily adapted to specific needs and verticalized in various applications.
